I checked that the "/home/wchan/wl500w/broadcom/src/linux/linux-2.4.37.10/include/asm" is missing. should I manually create a symbolic link to asm-mips? :confused:

i.e. ln -sf asm-mips /home/wchan/wl500w/broadcom/src/linux/linux-2.4.37.10/include/asm

Seems to be you have slightly different host environment, try to
make kernel
from src/gateway before "make"

Something goes wrong on your host env. This link should be created automatically by kernel's Makefile. Also check .config file presence in kernel directory.

I did the symbolic link then try the make kernal again. Now I got this error and I am completely lost.

should I try the RTN version of wl500w instead? Does RTN version has better support for usb sound?

lly

26-11-2010, 07:53

Does RTN version has better support for usb sound?
Generally - no, since 2.6.22 is very old kernel and usb sound support on router is not our primary task. Of course, some parts of sound subsystem definitely newer in 2.6.

snowx

26-11-2010, 17:54

back to the compilation then... how do I proceed? Any clue?

Unless you get some knowledge about Makefiles & linux kernel , you can't proceed. ".config" you mentioned are totally different. kernel's default config stored in src/linux/linux/arch/mips/defconfig-bcm947xx and later copied to src/linux/linux/.config

Is the rtn build stable? how does it compare to the 2.4 version?

Please read info at http://wl500g.googlecode.com/ - it's beta.

If someone can describe to you all difference between 2.4 & 2.6 kernels in a few words, he(she) will be true hero.

I think you've gotten me wrong. I just want to know the difference between the rtn and the d build of wl500w. Not the difference between the two kernel version. The components that concerns me are the webcam support and wireless stability.

As you can read in forum, wireless driver provided by Broadcom in binary blob, so we can't modify it.
Single major difference between rtn & d branches is ... kernel 2.6. Key points is here - http://code.google.com/p/wl500g/wiki/News

Hi wpte,

I was thinking about oleg and USBoIP ...

but I've also found an opensource one with beta support for windows (so it's cross platform)

this sounds very interesting. I was looking for such sw two years ago for the MGB100 but couldn't find anything free (no, there was one abandoned version in japan); still was hopeing that AVM would release/leak the code for the fritzbox

So, I was experimenting to link httpd with mini-lzo.
http://www.oberhumer.com/opensource/lzo/#minilzo

it only adds around ~5kb to the binary, while it can decompress webpages.
If we pre-compress the webpages, it's possible to save around 40-50% of the total size, which is around 300kb.

good idea?:D

Since webpages resides on root filesystem(squashfs) which already has lzma compression support, IMHO it will take no effect.

Yes, I was thinking about it while I should have remembered that part:o

Hey, I'm using the new firmware, with a WL500GPv2.
I was wondering if it would be possible to see a list of all attached devices.
I saw the DHCP leases, where you find a MAC address an IP and some host name.
When you click at wireless, you see (I think) the devices attached, but just with MAC address. Could it be possible to also show the hostname and IP?

Also, another question, if I would like to packet sniff everything what goes through the router (so LAN & WAN), what would be the best way to do this? (If possible of course)

Many thanks for this great firmware!

I was thinking about oleg and USBoIP since things like sane don't work that fast... only 1 A4 sheet in 5 minutes on 300dpi:p
So I guess usb over ip is a lot faster.

obviously you got the fantastic closed source solutions: http://usb-server.com/index.html
but I've also found an opensource one with beta support for windows (so it's cross platform)
There is USB/IP (http://usbip.sourceforge.net/) open source project with working solution (http://www.nslu2-linux.org/wiki/HowTo/UseUsbIpOnTheNSLU2) on OpenWRT. Server side includes two kernel modules and userspace daemon.

Windows client is ready (http://citylan.dl.sourceforge.net/project/usbip/usbip/usbip-win-preview/usbip-win.zip), kernel modules for RTN-fork too (http://www.wl500g.info/attachment.php?attachmentid=7509&d=1294685813). But userspace daemon with two dependencies still hard to compile.

Since r2486 revision rtn fork supports USB/IP (http://sourceforge.net/projects/usbip/), which helps you to use USB devices without specific linux drivers at all!

USB/IP project now has restrictions with some compound USB-devices. We tested a number of USB-devices. Successfully:

USB-HDD. R/W speed is ~5,5MB/s at ~60% CPU load,
Canon printer with CARPS drivers,
D-Link DBT-122 bluetooth dongle,
USB mouse.

Won't work:

USB-sound card (http://www.dealextreme.com/details.dx/sku.22475),
ZTE MF626 3G-modem.

To use USB/IP it is necessary to tune a server part on a router and a client part on the PC where the USB-device will work on.

1. Tuning of the server part.
The server part consists of two kernel modules and a userspace daemon.
1.1. USB/IP modules are included in modules-1.9.2.7-rtn-rÕÕÕÕ.tgz. Download and plug them:

$ cd /opt
$ wget ftp://core.dumped.ru/rt-n/2486/modules-1.9.2.7-rtn-r2486.tar.gz
$ tar -xzvf ./modules-1.9.2.7-rtn-r2486.tar.gz
$ modprobe usbip
1.2. The userspace daemon is compiled as a ipk-package. You can attach a corresponding repository and do not think about manual updating. It is necessary to add following lines in a file/opt/etc/ipkg.conf

src/gz wl500g-d http://wl500g.googlecode.com/svn/ipkg/optware-d
src/gz wl500g-optware http://wl500g.googlecode.com/svn/ipkg/optware

and install the daemon:

$ ipkg install usbip

Start the server part:

$ usbipd -D
Now we have to look at the list of USB-devices which can be exported:

$ usbip_bind_driver --list
List USB devices
- busid 2-2 (2001:f111)
2-2:1.0 -> none
2-2:1.1 -> none
2-2:1.2 -> none

- busid 1-1 (04fc:0c25)
1-1:1.0 -> usb-storage
The last USB-device 1-1 is a USB-HDD. Do not use uspip with it! Now it is necessary to make the device 2-2 accessible on the client side:

$ usbip_bind_driver --usbip 2-2

2. Tuning the client part.
The client part for Linux exists and is packaged in most of popular distributions. Windows client is here (http://sourceforge.net/projects/usbip/files/usbip_windows/), lets make it work.
2.1. Install USB Bus enumerator driver with USBIPEnum.inf. If successfully installed, the device will be named "Virtual USB Bus Enumerator" in section "System Devices" on Device Manager.
2.2. Starting the userspace part. Usbip.exe must be started with Local Administrator credentials.
Lets look what devices are exported by the server:

C:\usbip>usbip.exe -l 192.168.0.1
usbip dbg: usbip_network.c: 229 (tcp_connect ) trying 192.168.0.1 port 3240

usbip dbg: usbip_network.c: 249 (tcp_connect ) connected to 192.168.0.1:3240
- RTRouter
usbip dbg: usbip.c: 423 (query_exported_devices) exportable 1 devices
2-2: unknown vendor : unknown product (2001:f111)
: /sys/devices/pci0000:00/0000:00:04.0/usb2/2-2
: unknown class / unknown subclass / unknown protocol (e0/01/01)
: 0 - unknown class / unknown subclass / unknown protocol (e0/01/01)
: 1 - unknown class / unknown subclass / unknown protocol (e0/01/01)
: 2 - unknown class / unknown subclass / unknown protocol (ff/ff/ff)
We see earlier exported device 2-2. Now connect it:

C:\usbip>usbip.exe -a 192.168.0.1 2-2
usbip dbg: usbip_network.c: 229 (tcp_connect ) trying 192.168.0.1 port 3240

usbip dbg: usbip_network.c: 249 (tcp_connect ) connected to 192.168.0.1:3240
usbip dbg: usbip.c: 147 (query_interface0) exportable 1 devices
usbip dbg: usbip.c: 164 (query_interface0) 2-2: unknown vendor : unknown product (2001:f111)
usbip dbg: usbip.c: 165 (query_interface0) : /sys/devices/pci0000:00/0000:00:04.0/usb2/2-2
usbip dbg: usbip.c: 166 (query_interface0) : unknown class / unknown subclass / unknown protocol (e0/01/01)
usbip dbg: usbip.c: 186 (query_interface0) : 0 - unknown class /unknown subclass / unknown protocol (e0/01/01)
usbip dbg: usbip.c: 186 (query_interface0) : 1 - unknown class /unknown subclass / unknown protocol (e0/01/01)
usbip dbg: usbip.c: 186 (query_interface0) : 2 - unknown class /unknown subclass / unknown protocol (ff/ff/ff)
usbip dbg: usbip.c: 189 (query_interface0)
usbip dbg: usbip_network.c: 229 (tcp_connect ) trying 192.168.0.1 port 3240

usbip dbg: usbip_network.c: 249 (tcp_connect ) connected to 192.168.0.1:3240

new usb device attached to usbvbus port 1
Then there should be a driver installation dialogue of the device connected to the router. The device will be visible in the Device Manager as if its connected not to a router, but to windows PC:). Don't close the window with the usbip.exe started!

3. Shutting down.
To shut down USB/IP correctly, it is necessary to execute above listed step in reverse order.
3.1. On the client side open a new cmd.exe window and type:

C:\usbip>usbip.exe -d 2-2
3.2. On the server side (the router), disconnect USB/IP driver from USB devices:

$ usbip_bind_driver --other 2-2
** (process:385): DEBUG: write "del 2-2" to /sys/bus/usb/drivers/usbip/match_busid
** Message: bind 2-2 to other drivers than usbip, complete while using USB-device!

Then stop the daemon:

$ killall usbipd

4. Notes.

All the hard work for USB/IP adapting is done by theMIROn (http://www.wl500g.info/member.php?u=18446) è lly (http://www.wl500g.info/member.php?u=7094). Thanks guys!

dunno if that's a debug message, but I modprobed usbip.ko

devices are detected properly and while mounting:

** (process:5888): DEBUG: 1-2.1:1.0 -> usb-storage
** (process:5888): DEBUG: unbinding interface
** (process:5888): DEBUG: write "add 1-2.1" to /sys/bus/usb/drivers/usbip/match_busid

Yes, it's a harddrive connected through an usb hub.
I umounted the hdd first obviously.
The other harddrive is connected straight to the router, but I don't think it's a good idea to force umount /opt and share it over usb:p

anyway, I've tried the rtn version of the wl-500w firmware.
Now, is this supposed to work or is it for future development?
When I flash it with the restoration tool the device won't reboot after 10 minutes, and when I re-apply power myself it doesn't look like the router is going through a boot process at all:confused:

If you compile rtn FW for WL500W yourself, I suppose it's incomplete automation in Makefile.top - your kernel MUST be MIPS32R1

If you compile rtn FW for WL500W yourself, I suppose it's incomplete automation in Makefile.top - your kernel MUST be MIPS32R1

well it seems like the logic is correct:

$(LINUXDIR)/.config: .config
cp $(LINUXDIR)/arch/mips/defconfig-bcm947xx $@
$(call SwitchConfParam,$@,CONFIG_IPV6,$(if $(CONFIG_IPV6),y,n))
$(call SwitchConfParam,$@,CONFIG_CPU_MIPS32_R1,$(if $(filter WL%,$(MODEL)),y,n))
$(call SwitchConfParam,$@,CONFIG_CPU_MIPS32_R2,$(if $(filter RT-N%,$(MODEL)),y,n))

which should switch:

# CONFIG_CPU_MIPS32_R1 is not set
CONFIG_CPU_MIPS32_R2=y

I can try to manually set it to R1 to be sure:)

I just manually selected it yes, and works:)
I noticed that my WL-500W which I use as wireless ethernet bridge has a better sensitivity now and higher throughput :D

Now I know that my automatic building script doesn't work because I first do "make" which builds vor mips32r2, then I run something like "make install MODEL=RT-N16" so that's not going to work:p
So the error is with me, allthough I didn't test if the logic in the makefile works:)

Upgraded to RTN firmware on the WL500gP today.
Got everything working but cannot figure out how to get sound working.
Attaching a USB soundcard does not load a kernel module and there's also no /dev/sound
I want to try to get ESD working
Can anybody tell me how sound support is now implemented and what to do?

Sound kernel modules are available in the modules.tar.gz file ;)
The RTN firmware already includes sound modules:

/lib/modules/2.6.22.19/snd-hwdep.ko
/lib/modules/2.6.22.19/snd-mixer-oss.ko

Attaching a USB soundcard does not load a kernel module and there's also no /dev/sound
I want to try to get ESD working
To make any USB Audio Class 1.0 standards compiant soundcard work do:
1.1 Try to load kernel modules automatically

insmod soundcore
insmod audio
1.2 If it fails due to "modules.dep" absence, load modules manually in those order:

insmod soundcore
insmod snd
insmod snd-timer
insmod snd-page-alloc
insmod snd-pcm
insmod snd-hwdep
insmod snd-rawmidi

Mine (http://www.dealextreme.com/details.dx/sku.22475) works fine.

There is no ESD-daemon, just OSS.

It seems to work :-) Thanks a lot for the instruction.
I guess it is not initialized automatically due to the abscence of the waveserver. I got ESD from: http://home.in.tum.de/~pustka/WL-500g_as_wireless_soundcard.html
In Kernel 2.4 it just caused an endles beep when playing.

Is it still needed to recompile firmware to make use of both serial ports of the asus wl500g deluxe with the new firmware? I only found a 5 year old thread about recompiling the kernel, but I have never recompiled a kernel before, so I would like to know if this is necessary, and how I should accomplish this.

Please try r2837, will bug appear? If yes, try to turn off fastnat by

I can't flash firmware atm since the router will crash after firmware flash & shutdown.
Anyway, I thought fastnat was disabled by default, I turned it off and rebooted which solved the problem:)
All my internet is tunneling through openvpn again:)

Unfortunately, Broadcom's fastnat isn't as smart & flexible as can be imagined. theMIROn tries to improve it, but it is not so easy task.

Yeah, I've seen the conversation on google code.
Isn't fastnat just faster because it isn't completely compatible with some networking things?

I think the fastnat patch is good since you have more performance, unless you use something like openvpn:p
Also not many people have that internet speed, yet:)

I think the UPnP deamon is dead again:)
On several computers that used to work with upnp it simply won't show up anymore.

And when I run my little tool that discovers the devices using this broadcast string:

string req = "M-SEARCH * HTTP/1.1\r\n" +
"HOST: 239.255.255.250:1900\r\n" +
"ST:upnp:rootdevice\r\n" +
"MAN:\"ssdp:discover\"\r\n" +
"MX:3\r\n\r\n";
the router simply does not respond to that packet, other devices do tho:)

killall upnp

i=`expr index $line "="`
let i=i-1

nvram unset $rule
done
upnp -D -L br0 -W ppp0

That seems to work, probably because killall says there's no upnp running.
I do have it enabled in the web-admin.

I edited your script a bit so that it knows what lan and wan is:

#!/bin/sh
killall upnp
for line in `nvram show | grep "forward_port" | sed "s/ //"`
do
i=`expr index $line "="`
let i=i-1
rule=`expr substr $line 1 $i`
nvram unset $rule
done
upnp -D -L `nvram get lan_ifname` -W `nvram get wan_ifname`

Thanks.
I also happen to know this one http://koppel.cz/cdmawifi/english/ which adds USB modem support. It is the only ready to use firmware capable of transforming an old WL-500g into a 3G router that I know of. But development stopped in 2008 too.

I recently found a new firmware from IIy WL500gpv2-1.9.2.7-d-r2624.trx,
everything works perfectly also choose samba is finally corrected, but I have a big problem: if I connect to ssh ce MC and root disk is displayed incorrectly and I can not browse folders with no view and copy the file.
I see the following directory structure shown (as in the picture attached) for example
/tmp"
/etc"
/dev"
and it is not possible to work... in the previous version of Oleg, the problem don't, all correct.
What is wrong?
Even had an idea, of that can be used by another character set, but I'm not sure.

What is wrong?
It is a known bug in MC, appeared on busybox target systems only. Fixed in current stable versions (I use 4.7.5).

An old Oleg FW has very old busybox which hasn't some new features used by MC fishfs.

I use my WL-500W as a wireless ethernet bridge to my RT-N16.
so you plug in ethernet cables and it'll send the packages over wireless to the RT-N16.:)
I noticed:
- the connection is always alive, under the -d firmware it would stop working sometimes.
- Better sensitivity of the network
- Higher throughput

so yeah, you could say so:)

I'd like to play around with tcp_vegas a bit so I loaded the module with modprobe, but somehow the files don't appear in the /proc/sys directory:

echo 1 > /proc/sys/net/ipv4/tcp_vegas_cong_avoid
-sh: can't create /proc/sys/net/ipv4/tcp_vegas_cong_avoid: nonexistent directory

the log shows that vegas is registered tho:

kernel: TCP vegas registered

also the available methods show vegas:

cat /proc/sys/net/ipv4/tcp_available_congestion_control
cubic reno vegas
any ideas?:)

doc: http://neal.nu/uw/linux-vegas/

Never mind, I think I got it working in the other way:p

modprobe tcp_vegas

cat /proc/sys/net/ipv4/tcp_available_congestion_control
cubic reno vegas

#setting it to vegas
echo vegas > /proc/sys/net/ipv4/tcp_congestion_control

wow.. I thought broadcom driver is not compatible with 2.6 kernel but this means it is? Does moving to this firmware from the regular 2.4 based images released over at http://code.google.com/p/wl500g have any impact on apps that are installed or is it a straight upgrade?

no, nothing will have to change on your harddrive(s), nor the flashfs.
I only had some problems with the nvram (web-admin) settings, apart from that the installation of the k2.6 firmware is as smooth as a rock;)

Can anyone tell me how to install WL500gpv2-1.9.2.7-rtn-r2972.trx? I have no problem with the -d release, but that one doesn't seem to flash. The power light starts blinking and then it gets stuck. Obviously into a WL500 GP v2. Thanks.

have you tried the firmware restoration tool?
flashing might take a while with it, sometimes like 5 minutes:)

The one from Windows? (un)fortunately I use a MacBook. I tried with a virtual machine but obviously it messed up. Now I installed Win7 in a partition and that may help in case.

What i did has been to upload the fw from the web interface. it works fine (and fast) with the -d release. With the -rtn I don't know what it happens.

I managed to unblock the router using the wl500g-clear-nvram.trx and wl500g-recover.trx via tftp, fortunately I've found some instructions in the ww-drt site.

So, my only guess is that it really should take 5 minutes to install? How do i know if the firmware has been installed? I am not sure because I messed up, but I thought that in one try I left the router on for 10 minutes or so, but I can remember wrong. Anyway, what do you suggest? The Windows tool?

wpte

24-06-2011, 19:23

Michelasso

25-06-2011, 00:28

Well you could use the mac osx build in tftp client to upload the firmware.
In the end... that's all the windows tool does:)
If you're running a VM of windows you could try to bridge the network adapters, that way it might work as well:)

That's what I did indeed (upload via tftp). Still the rtn version seemed to not load. I check the M5 number and it is correct, so it isn't a file corrupted problem. I will try maybe tomorrow, waiting few 10 minutes this time. I know how to restore the old firmware anyway if anything goes wrong again. Thanks. I'll let you know.

Michelasso

27-06-2011, 09:27

Nothing. I am totally unable to install the rtn release of the wl500gp v2 fw. I tried also with the restore utility from Windows and it got stuck waiting for an IP address. I gave a static IP address (192.168.1.2) to Windows and same thing. Uploaded via tftp, binary mode (octet) it got uploaded (I enabled trace as well) and that's it. Left on for 10-20 minutes, nothing happened.

How do you guys flash the rtn version?! I need it because I read it might fix a problem with the WiFi (that in my case it can disappear for weeks, but the light is on and then sometime it reappears). This is very frustrating.

I'm sorry it doesn't work for you:(
I only have a wl-500w and a rt-n16, both just flash fine trough the web-interface.
Also the wl-500gPv2 should be compatible with the rtn branch.

You've also tried restoring to factory defaults before flashing?
have you also tried newer builds: http://wpte.kicks-ass.net/downloads/Oleg%20Firmware/Nightlys/1.9.2.7-rtn/3101/wl-models/ ?

I flashed the WL500W-1.9.2.7-rtn-r3121.trx on my asus wl-500w this weekend. Everything seems to be working great but I see one issue. UPnP no longer works. None of my programs that use upnp for opening ports are able to do so. Even transmission (running on router itself) is not able to open the incoming port and shows it as closed. On checking the Status & Log -> Port forwarding page, it is completely blank, not even a single port forwarded, which is strange because I run a lot of services on my PC, PS3 and router that forward ports through UPnP and earlier this page used to be filled with atleast 15-20 ports always.. I've enabled UPnP (yes, report wan address) under IP Config->Miscellaneous. Any ideas?

Have you tried resetting the router to factory defaults to check if it's not a configuration problem?
Also, if this tool (I made) can find it nothing should be wrong: http://code.google.com/p/csharp-upnp-portmapper/ (it's still very simplistic)

Also you could try these settings:
IP Config - Miscellaneous -> Efficient Multicast Forwarding: Disabled
Wireless - Advanced -> Enable WMF? Yes

Your firmware version has a upnp patch that stopped the upnp daemon from crashing (an issue I experienced myself)
You can use this script to reset the upnp daemon:

#!/bin/sh
killall upnp
for line in `nvram show | grep "forward_port" | sed "s/ //"`
do
i=`expr index $line "="`
let i=i-1
rule=`expr substr $line 1 $i`
nvram unset $rule
done
upnp -D -L `nvram get lan_ifname` -W `nvram get wan_ifname`
(thanks to ryzhov_al for this script)

WMF is about wireless multicast only, it's not related with UPNP.

You can use this script to reset the upnp daemon:
FW has miniupnpd, not upnp as daemon, script is useless.
And, that's why leases are not saved after restarts.

Ok, another installer, and not even a dedicated upnp-nat program

WMF is about wireless multicast only, it's not related with UPNP.
When I disabled it I couldn't find any media server wirelessly anymore, since that happens using SSDP (what upnp uses) it is a thing to try out.

Hi wpte/theMiron

I tried all your suggestions.
Efficient multicast forwarding and WMF are already disabled.
When I run wpte's tool, it is able to map the ports well..

However, when I run the tool suggested by theMiron, it gives following output:

TEST 1 - Operating System Support - PASSED
TEST 2 - SSDP Service Running Check - FAILED
TEST 3 - SSDP Service Automatic Check - FAILED
TEST 4 - UPnPHost Service Running Check - FAILED
TEST 5 - UPnPHost Service Automatic Check - FAILED
TEST 6 - UPnP Framework Firewall Exception Check - PASSED
TEST 7 - Adapter #0 - 192.168.0.7 - PASSED
TEST 8 - Get External IP Address (Result: x.x.x.x) - PASSED

These are all run on my PC. Router is connected directly to my ISP's cable without any modem in between and gets the external IP assigned correctly. Also, I downloaded utorrent and ran that and that is also working fine for adding ports through upnp.

However, the programs that I run on my router itself (e.g. transmission) are not able to open the ports through upnp and the port always shows up as closed. I'm very confused by all these results :(. Unfortunately I'm pretty naive with upnp/nat-pmp etc and couldn't debug anything more. Please let me know if I can provide any more information.

add them (ports) to the vserver or to post-firewall directly

shantanugoel

add them (ports) to the vserver or to post-firewall directly
Yeah, I can do that but I have set transmission to use random ports..I can set it to use fixed port for now and get by this issue but just interested in seeing if the problem can be fixed..

Anyways, I did some more searching around and debugging. Used a tool from http://bitlet.org/upnp and it reports no UPnP enabled gateway devices found. Also ran transmission with debug logging mode and saw that UPnpDiscover and UPnP_getValidIGD calls were failing. Searching for this on transmission forums lead me to this ticket https://trac.transmissionbt.com/ticket/3452 where they mention that this problem started happening when they "fixed" their code to use proper return values from UPNP_GetValidIGD. Earlier they were just checking for >1 and now they check specially for 1.

miniupnp says:

/* UPNP_GetValidIGD() :
* return values :
* 0 = NO IGD found
* 1 = A valid connected IGD has been found
* 2 = A valid IGD has been found but it reported as
* not connected
* 3 = an UPnP device has been found but was not recognized as an IGD
so miniupnp is getting confused and returning 3, basically not finding any valid IGD. Searching on miniupnp forums, it is mentioned that this is a router problem, not a miniupnp problem.

Just thought of providing this information in case you can make some connections :)

theMIROn

13-07-2011, 15:26

please try following (on the router):
1. killall miniupnpd
2. edit /etc/miniupnpd.conf:
search for

listening_ip=...
...
allow 1024-65535 ... 1024-65535
...

and insert lines as following:

...
listening_ip=127.0.0.1
listening_ip=...
...
allow 1024-65535 127.0.0.0/8 1024-65535
allow 1024-65535 ... 1024-65535

that was the only post I made about the problem.

I'm not quite sure, I just use upnp-nat every now and then and noticed it didn't work:p

shantanugoel (a few posts back) had issues, I remember that before that I had no problems with miniupnpd. after that there's only this update: http://code.google.com/p/wl500g/source/detail?r=3169 as far as I can see in the svnlog.

the configuration seems correct as well:

presentation url is on the same port as my web-admin, that's ok I guess?

Anyway, I checked it just now, and suprisingly it works:confused: there is no more message about the sub network either...
I didn't change anything either:o

shantanugoel

yeah..the issue I had with miniupnpd was that programs running on router itself are not able to open any ports but programs running on my PC can open ports. Using 127.0.0.1 in listening_ip in the configuration didn't solve the problem as well but I noticed that if I run miniupnpd with the listening IP specified on the command line as 127.0.0.1 instead of specifying in config file, then the programs running on the router are able to open ports.

100% cpu usage already fixed in r3479 ;) It is a bug inside miniupnpd. I would be glad if someone opened a problem at miniupnpd's forum, I haven't enough time for it.

True root of problem should be investigated, but I can't reproduce this bug myself. Probably, recipient close other end of pipe too early and miniupnpd either don't parse response correctly or it is an hole in workflow...

My bad, I looked over that update:o
I've only had it once as well... it's a rare problem I guess...
Looks like a problem with the upnp request parsing, I don't understand why they don't use the intel upnp toolkit (it's a bit bigger in size I guess) since it has been running completely stable here in C here.
I experiment with it to control the QoS rules based on what programs the client PC is running, so that you'll always have optimal rules :D

I've noticed it only now, but cannot guess what it is. Nothing was connected to the router at that time not even via OpenVPN although it was running.

Do you have some idea what's causing this or how to figure it out (what client it refers to)?

Some client send command to unlisted interface or it is a bug inside miniupnpd.
I can add debug print about sender IP to miniupnpd only.

P.S. Unfortunately, miniupnpd is far from ideal daemon...

I've stopped twonkymedia and the messages disappeared. After starting it again they have appeared immediately.

I'm not familiar with UPnP protocols, but twonkymedia really issues SSDP M-SEARCH command.

Probably, we have to add "listening_ip=127.0.0.1/8" into miniupnpd.conf

As I can see in miniupnp sources, there should be one diagnostic string more in syslog.log, like:

SSDP M-SEARCH from 0.0.0.0 ST: ???"

Are you logging errors only? Could you provide output of following comands

ps|grep syslogd
nvram get log_level_x
?

I've stopped twonkymedia and the messages disappeared. After starting it again they have appeared immediately.
Maybe there is something wrong with my configuration even though it's nothing special compared to the factory twonkymedia-server-default.ini.

Anyhow, thanks for quick responses.

Hmm... what version do you use?

I'm not familiar with UPnP protocols, but twonkymedia really issues SSDP M-SEARCH command.

Probably, we have to add "listening_ip=127.0.0.1/8" into miniupnpd.conf

I've implemented the entire basic UPnP stack for control points(the clients) and devices(servers in common computer language:p) while working on a uni project.
I've done a quick capture with wireshark and this is what I got:

M-SEARCH * HTTP/1.1\r\n
MX: 3\r\n
ST: urn:schemas-upnp-org:device:RemoteUIServer:1\r\n
HOST: 239.255.255.250:1900\r\n
MAN: "ssdp:discover"\r\n

I guess that's the ssdp m-search package you're talking about.
My comment on this: It's a correct package according to the UPnP Device architecture document:

M-SEARCH * HTTP/1.1
HOST: 239.255.255.250:1900
MAN: "ssdp:discover"
MX: seconds to delay response
ST: search target
(without the line endings, but they're supposed to be windows style)
All the required values are defined, but in theory shouldn't follow the exact same order.

So in my quickly formed opinion this is a bug in the way miniupnpd handles it's m-searches.
blocking out the local host could work, unless you have a bad network and packages bounce back :)

I've solved the issue via adding ip=192.168.1.1 to twonkymedia.ini.
In this way it's restricted to LAN interface. I don't know if it's any issue, probably not.
Please correct me if I'm wrong.

I'll skip checking this issue further in upnp as I'm not familiar enough with it.

Btw. twonkymedia version is 6.0.37.

I'm not sure ecaddict... an m-search is just a udp broadcast so an ip should be resolved by the control point (miniupnpd in this case), setting an ip for the device shouldn't make a difference:confused:

M-SEARCH has a multicast target address, but sender(source) address in packet is?

To be sure to do this, we must know that sender IP neither anycast, nor multicast. Right?
Since I haven't twonkey, I ask wpte & ecaddict for information.

M-SEARCH has a multicast target address, but sender(source) address in packet is?

Yes, the ip-endpoint is set at 255.255.255.255:1900
then an ipv4 socket is created with udp and datagram (http://en.wikipedia.org/wiki/Datagram_socket) settings.

then twonky sends the m-search message 3 times (according to upnp spec)
and reads the responses back.

It's importand that if you have multiple devices on 1 host that either way you solve the problem of multiple sockets on 1 interface with a root device (which could act like a sort of switch) or like most programs do because of compatebility issues: do not bound on the socket but simply send and receive data.

In my programming I've never had to use the ip of the device... well... only for serving the service, but not for m-searches and responses:confused:
In wireshark the ip of the twonky m-search just popped up as my router ip, as expected.

I can confirm that running the following commands:

killall miniupnpd
cat >> /etc/miniupnpd.conf << __EOF__
listening_ip=127.0.0.1
allow 1024-65535 127.0.0.0/8 1024-65535
__EOF__
miniupnpd
ps afx | grep miniupnpd

makes it unnecessary adding the ip=192.168.1.1 to twonkymedia.ini so that the strange logs disappear.

I don't know if this information is any help to you.

Seems like an easy fix tho.
This could explain why twonky didn't cause the messages after it knew the ip the broadcast on...
It's too bad the developers didn't include this by default, on a port-forwarding application it would be a good security feature in my eyes.

I just use the script wengi proposed in his how-to:

#! /bin/sh

/opt/etc/init.d/rc.unslung stop

sleep 10s

for i in `cat /proc/mounts | awk '/ext3/{print($1)}'` ; do
mount -oremount,ro $i
done

swapoff -a

sleep 1s
I have used that for a long long time without any issues:)

I have to note that the reboot without the harddrive attached did feel like it took longer than normal.

Hi,

Currently i'm using USB 3g modem in rt-n16 with the latest firmware.
i need to send some AT commands before making the connection and similarly after making the connection. With the help of additional AT commands option i could send pre-connection AT commands successfully. But i couldn't able to send AT commands after successful connection. Is there any way its possible?
I tried setting up post-firewall, but it was not successful.
Any help or some hint much appreciated :)

I've succeeded with post-firewall script and now new problem is, post-firewall event doesn't fireup when the pppd(3G) connection disconnects and reconnects automatically. Any help here?

Basically i want to execute an script, after successful wan connection, similar to wan-up in tomato and i'm not sure whether this is possible here or not?

Hello guys,

I have a strange problem. After upgrading to rtn 3702 on my ASUS WL-500g Premium, mounting order of my partitions went FUBAR. I have three, SWAP, OPT and data partition, all was set in the FStab in previous version of the firmware. But after an update, the partitions get mounted automatically to some default mountpoints, and I am unable to locate the fstab in the /etc to specify the mount order. Remounting them manually of course solves the problem, but this is real pain in the ass to do after each reboot...

Any help appreciated.

ryzhov_al

11-02-2012, 14:19

You may try to mount partition by its labels. Here is an example:

$ cat /etc/fstab
LABEL=SWAP none swap sw 0 0
LABEL=OPT /opt ext3 rw 1 1
LABEL=STORE /tmp/store ext3 rw 1 1
LABEL=DOWNLOADS /tmp/downloads ext3 rw 1 1
#LABEL=DOWNLOADS /tmp/downloads ext4 rw,barrier=0 1 1
Firmware tries to mount first avaliable partition at /tmp/mnt/diskX_Y and symlink it to /tmp/harddisk automatically.

You have to read forums FAQ/tutorials more attentively. Flashfs content can be lost if upgrading from firmware with big difference in .trx size. You simply have to backup/restore it.

Moreover, fstab for 2.4 kernels (1.9.2.7-d) incompatible with 2.6 one (1.9.2.7-rtn).

Does the Asus provide a "/etc/sysctl.conf" (I couldn't find one)?

No, it not included for size reason. You have to directly write to:

/proc/sys/net/core/rmem_max
/proc/sys/net/core/wmem_max

With this, it seems that my router is not reachable via Web-IF (ssh works, though).
After reboot, no message like this and everything is fine.

you may try to re-compile whole firmware with SLAB allocator turned on by default in kernel, maybe it'd help (by default SLUB is selected).

it helped me to reduce load on my wl500gP equipped with BCM43222.

Regarding the ports-problems --> what is the preferred way to enable UPnP?

Thanks for help,

Check Virtual Server in WEB interface, I do not trust uPNP, better forward certain ports to your computer/router.

Well you can easily configure this in post-boot

echo 256960 > /proc/sys/net/core/rmem_default
echo 256960 > /proc/sys/net/core/rmem_max
echo 256960 > /proc/sys/net/core/wmem_default
echo 256960 > /proc/sys/net/core/wmem_max

I've even added some extra settings:

echo 0 > /proc/sys/net/ipv4/tcp_timestamps
echo 1 > /proc/sys/net/ipv4/tcp_sack
echo 1 > /proc/sys/net/ipv4/tcp_window_scaling
echo 30 > /proc/sys/net/ipv4/tcp_fin_timeout
echo 30 > /proc/sys/net/ipv4/tcp_keepalive_intvl
echo 5 > /proc/sys/net/ipv4/tcp_keepalive_probes
echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle
echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse

turning off the tcp_timestamps actually gives me 200-300KB/s extra speed:eek:
note that this might break some traffic, but timestamps are hardly used in my experience:D

True... but it's easy :)
If you run a tight ship when it comes to security, you should be good. If you don't it's not that smart.

btw, does anyone have experience with a 3TB harddisk and oleg?
Can I just create one giant 3TB partition? I know windows has troubles with it, but I'm not sure about linux :)

there is a GUID support inside 2.6.22.19 kernel firmware by default, it should work I think.

about NAT ports, well you just need to forward certain applications which you really need, ofc you need to use latest version and patch them.

It doesn't depend on the OS alone. The filesystem (http://en.wikipedia.org/wiki/List_of_file_systems) is imho more important.

ext4 for example supports volumes up to 1 Exbibyte where ext3 supports max 16 Tebibyte per volume...

I'm waiting silently waiting for my RT-N66U to get oleg as well (not trying to rush the devs;) )

well, RT-N16 is based originally on 2.6 I believe, that's why it works ok, but with wl500gP situation is different, the most stable situation with this router is on 2.4.20 kernel, low CPU load, irq usage etc. But the problem is I can't use it due closed-source wi-fi driver which is only available for 2.6 branch.

I partially solved some issues with SLAB allocator and tuned kernel config a bit, but I think it's still not perfect under load.

For example I'm running few openvpn tunnels on 2.4.20 kernel they were eating 0.20 0.10 maximum load, but on new firmware with 2.6.22.19 0.50,0.35,0.22.

Also there is huge load when you're downloading something from LAN, on default options CPU is reaching 100% load. If I didn't alter kernel config it'd be useless (i can't open any site and can't use anything).

Actually my wl500gP equipped with BCM43222 as I noted before + I flashed WL500W firmware, so it's like yours WL500W.

Regarding opkg I just tried it and I think I'd stick with oleg's optware, just because I'm so used to it and I don't want to break existing packages.

Good news for the people that use OpenVPN!

If you keep an eye out on the changelog of Oleg firmware you might have noticed r4318 (https://code.google.com/p/wl500g/source/detail?r=4318).
This update finally fixes fastnat to work with applications like OpenVPN. This means everyone should be able to turn on fastnat without any problem!
theMIROn (http://wl500g.info/member.php?18446-theMIROn) who worked on this issue managed to fix it, and I'd like to thank him for that:)

For the people who don't know what fastnat is: fastnat is a piece of code to speed up the routing between wan and lan (nat).
Even if you have no super speed internet fastnat will save you some cpu load you can use on a whole lot of other things:p
So does it affect the OpenVPN performance? YES!

I did a little benchmark and came back with these results:
fastnat on:
down 8.00
up 6.36
fastnat off:
down 7.83
up 6.20
Results from http

So if you update your firmware to r4318 or later you are good to go.
note: this update is only available in the rt-n firmware with linux kernel 2.6.

So how do you check if you have fastnat enabled?

nvram get misc_fastnat_x
This line should produce the answer "1" (without the quotes).
If it doesn't here is how to turn it on:

nvram set misc_fastnat_x=1
nvram commit
Now reboot your router after this and it should work.
If you wish to turn it off again, just replace the 1 by a 0.

Actually my OpenVPN instance is running on the gateway-router.

My WL-500gP is running in access-point mode, so fastnat won't give me any performance benefits, if I would run the OpenVPN Service there right? :confused:

In AP mode the router works like a switch, so there's no lan-wan routing, just switching which is already fast;)

I'm playing around with EXT4 since I'm planning on buying a new 3TB harddisk.
My other harddisk is wearing out a bit so I want to replace it before it breaks down;)

I properly looked into the configuration of the kernel before thinking about going over 3TB.
I've seen UEFI was enabled which should allow the GTP partition system for >2TB disks.
For some reason I could never insmod the EXT4 module though I did insmod the dependencies before trying.
It always reported something about a missing symbol.

I decided to build a firmware with EXT4 build in rather than a module and found out while trying to mount, that one option should be enabled as well.

CONFIG_LBD=y
This will allow Large Block Devices to work. After applying this as well I found that mounting EXT4 worked fine.:D

wpte

Let me bump this:o

Do you guys think it's a good idea to go for a 3TB EXT4 formatted disk?

Also I think flashfs is not working on the current firmware. Is the firmware getting bigger again?;)

using r4680

I created the partition like this:

mke2fs -t ext4 /dev/sdb1
on the router.

I tried to make the ext4 partition with gparted :p
and it uses the command:

mkfs.ext4 -j -O extend -L "" /dev/sdb1
Also gave me the same error.

Either way the drive shows up at my pc correctly and is usable

on r4656 it seems to work. I'll try higher revisions tomorrow

Yes, with kernel-2.6/150-fs-ext4-updates7.patch removed it seems to work fine.
I've just compiled the modules, and loaded them up.

When I place the modules in /opt/lib/modules/2.6.22.19 it even automatically modprobes them, nice :)
I did unload the old modules by rmmod ext4, crc16 and jbd2.

I must say I like ext4 on the router so far. It seems to give a better performance in big file and directory situations. In ext3 it takes a long time to even list the files for some reason.
Also I was able to get about 0.5MB/s extra speed trough samba.

Eventually I want to move my /opt partition onto a ssd (with mlc memory) to save some energy and make my harddisk live a bit longer.

Only debugging can help. Did you try the same on regular Linux workstation or Windows?

Yes I did a full check (sector by sector) of the drive before I dumped all my data on it;)
I'm copying again, and I have a bit of a nasty memory leak feeling.
If it's a leak, the leak is probably small because the used memory is increased bit by bit very slowly.

lly

08-11-2012, 13:43

I've transferred over 400GB already, but I did noticed some hiccups.
EXT4 seems to work well overall, good performance etc.
But after a while (seems almost random) I get a segmentation fault in cp, the drive becomes inaccessible and the router is not able to umount it, even when the drive is removed.
I don't see any oops, maybe I should turn extra debugging on?
The router is also not able to reboot after the segfault.

In case of you can't reboot, it seems to be kernel problem.
It can be either ext4(jbd2) specific or common writeback/bdi interfaces problem. I never hear that somebody did such stress-test on router, 400Gb is really huge amount of data!

Best of all, if you able to prepare reproducible minimal test-case.
If problem is ext4 specific, than switching to ext3 will help. To enable ext4 debugging you have to recompile ext4.ko, jbd2.ko kernel modules with CONFIG_EXT4_DEBUG=y & CONFIG_JBD2_DEBUG=y

Also, please try r4652 - it is a small chance that I miss something in latest backports.

Anyway, "cp" shouldn't crash silently - please try to use gdb to get type of fault.

pff 400gig is nothing:p
But that's a total I copied. First I copied about 70GB when cp crashed, then after a hard-reboot I copied the rest without any problem.
I didn't found any corruption of the filesystem btw.

I remember that I had an incident with an other drive as well (a test ext4 drive). It was just spun down for a long time, it worked for days but then I wasn't able to umount or access it. I'm not sure if this is a stress problem.

I will run the cp command with gdb this time, and try the latest revision;)

Still going strong. I've been using my 4TB EXT4 disk as primary storage location for a few days now.
Soon I'll make a switch for /opt as well to an ssd so I'll have less wear on my big harddrive:D

I've no complaints but I'd like to give some feedback performance-wise.
I still use the debug-enabled modules maybe that's what causing extra load, but this is my load graph from the last week:
9343
You can clearly see a load increase while I didn't do anything different than usual.
Again no complaints from my side, I'm happy with EXT4, but it's interesting for people who may want to switch.

In the weekend I'll start using the debug-less modules again I guess, since everything has been running smooth.

My guess that is is due to our old bdi(backing device interface) kernel subsystem. Modern kernels has per-device bdi, our still use single kthread. Hope, I able to backport per-device bdi in futer, but it requires a lot of time & efforts.

I really think it was the debugging version that gave me the extra load.
yesterday I upgraded the modules, including the firmware and it seems to be pretty much the same load as it used to be again:
9348
The graph displays an entire week again.
So EXT4 means (almost) no extra load :D

Hi,

I installed WL500gpv2-1.9.2.7-rtn-r4667 on my WL500gP-v2 router.

I copied the root filesystem onto a usb disk. I checked "flashfs status" which says enabled. My USB device appears as /dev/disks/diska/part1, which is listed in the nvram as the boot_dev.

I was expecting this to continue booting from my attached USB stick as a previous Oleg's firmware version did.

Unfortunately, my USB disk no longer mounts as the root filesystem boot up. Instead, it is mounted a few seconds later in /tmp/mnt/disca_1

Please can someone tell me what I have missed?

Thanks,

Chris.

rootfs? the rootfs is installed on your router with the firmware image. Or do you mean optware?
Anyway, with the new version of the firmware you need to make a fstab to configure automatic mounting of usb drives.
Wengi has a great tutorial for this: http://wl500g.info/showthread.php?10307-How-To-Install-and-Configure-Olegs-firmware&p=60931#post60931 (part about fstab)

I followed the instructions at http://oleg.wl500g.info/ under section "Root file system on the external USB drive", but changing the boot_dev path to the new location, i.e. /dev/discs/disca/part1.

I was expecting the root file system to be pivot_mount'ed from the temporary rootfs to the persistent permanent copy on my USB stick. This used to work with the Oleg verison of the firmware under 2.4.x but no longer works on the 2.6.x kernel.

I see... that's pretty old stuff, I'm unsure if that's still supported.

Nowadays we have the Oleg based firmware for enthusiasts: https://code.google.com/p/wl500g/ which you have installed.
It uses a new toolchain, new uclibc etc etc.
So even if it's supported you might need to make a new rootfs stick because it's newer software:p

Usually people use a wengi-like tutorial like I've shown you in my previous response to install software on a disk mounted to /opt
Basicly you have a repository installed on that disk and you can install and update software on the fly. The rootfs on the router will just run next to that.
You have the ipkg repository as described in the wengi-howto, but also the new entware repo which uses opkg: http://code.google.com/p/wl500g-repo/
It allows you to install things like bash, lighttpd, mysql and a lot more. If you're familiar with debian linux boxes you probably know something like "sudo apt-get install ..." this is exactly the same.
Do I make sense a bit? ;)

Also another thing, you probably know these already, on this page the custom userscripts are explained: https://code.google.com/p/wl500g/wiki/UserScripts

wpte

07-12-2012, 23:51

question:
Is it possible to use the toolchain with ccache (http://ccache.samba.org/)?

I've added "export PATH=/usr/lib/ccache:$PATH" to my .profile
Also I've added the soft links to ccache like this:

ln -s /usr/bin/ccache /usr/lib/ccache/mipsel-linux-gcc
and so on for all the compilers, like mipsel-uclibc-cpp

The thing is, when I check the cache with

ccache -s
the files don't seem to get cached or hit at all...
only now and then I see some increases in the numbers

which gives a proper result however:

$ which mipsel-linux-gcc
/usr/lib/ccache/mipsel-linux-gcc

I'm positive ccache since I compiled the toolchain with it, and it seems to build a lot quicker now;)

I upgraded from old Olegs firmware to "renewed Oleg's firmware", WL500gp-1.9.2.7-rtn-r4772 on my WL500gP V1 router.
In old firmware I followed Wengi tutorial, formated my 80GB drive to swap, opt and data partitions, installed ipkg and instaled another software.
recently i bought webcam and tried to get it working (Logitech quickcam for notebooks) - not well supported ind 2.4 kernel, so I upgraded to 2.6 kernel.
Now the webcam is detected, but cannot get images from it (maybe problem of cam server). No problem at all, just minor glitch, I will try/use RaspberryPi for that.
But.
After upgrade (and few glitches with firmware restore tool, because i used improper firmware version - Wl500gpV2 for my V1 router:), I restored my nvram settings anf flashfs, got my connection to internet working, but my USB disk doesnt automount. I fixed my boot scripts in /usr/local/sbin to correct paths, modified fstab to new /dev/discs/disca/part1...3 paths. But still no automount. When I manualy start my post-boot, pre-mount, post-mount, post-firewall scripts, it works as expected.
In /tmp/syslog.log afted detecting USB disk by usbcore, drives get assigned sda1..3 simlinks in /dev and after that moment I can see in my log only ntp and dns updates.

Any thoughts/suggestions?

Thnax in advance.

Hi all,

please I need help with my new 3Tb drive, I cannot get working it :(

I know there is some discussion few pages before, but I am unsuccesfull. Can you recommend me the firmware I need to use?

Also I created partitions on my PC (but under windows7 with Acronis Disk Director, 3 partitions, 512MB linux swap, 1GB linux and the rest 2,7xxTB linux).

I dont know how to mount them?
Tried new fw (WL500gpv2-1.9.2.7-rtn-r4923.trx from "https://code.google.com/p/wl500g/downloads/detail?name=WL500gpv2-1.9.2.7-rtn-r4923.trx&can=2&q=").
I am normally using wengi tutorial but it seems that "/dev/discs/disc0/part3" is changed to something like "/dev/sda3"??

fdisk -l shows me:

Disk /dev/sda: 801.5 GB, 801569726464 bytes
256 heads, 63 sectors/track, 97071 cylinders

Device Boot Start End Blocks Id System
/dev/sda1 1 266306 2147483647+ ee EFI GPT

On PC i see 3 partitions.

Please advise me FW and how to mount the partitions.

Thanks very much

Edit: for many hours of laborating I discovered, that it is adapters that not support over 2TB discs :(
So my advise for future for others... The only way around this problem is to get an external enclosure/adapter that supports over-2TiB disks.

21-04-2013, 08:20

EDIT: I have to read post to the end, first I didnt notice the edit with enclosure unsuported disk size:)
But you could try to format partitions so they dont overlap max. supported size, my disk is maybe 1TB, but I cloned my old 80GB disk after its failure and never resized paritions...

For anybody looking to information to automount disk afer upgrade:

I am normally using wengi tutorial but it seems that "/dev/discs/disc0/part3" is changed to something like "/dev/sda3"??

try running mount, in the output you wil see list of mount points, "/dev/discs/disc0/part3" should be /dev/sda3. (on my WL500gp, or /dev/discs/disca/part3 on my RTN-16)

Edit /etc/fstab:

#device Mountpoint FStype Options Dump Pass#
/dev/sda1 none swap sw 0 0
/dev/sda2 /opt ext3 rw,noatime 1 1
/dev/sda3 /mnt ext3 rw,noatime 1 1
for comapatbility with my old scripts I added this command to post-mount script:

if [ ! -d "/tmp/harddisk" ]; then
ln -s /mnt /tmp/harddisk

The unfinished part in sdk5110 branch is ... kernel. Broadcom modifications couldn't be applied "As Is" due to they move open-source fast-NAT into closed ctf.ko blob :( theMIROn's advice is to follow Broadcom and replace BCM_NAT.

I archived the files in /opt, formatted this partition in ext4 as in instructions, connect the modules from the modules-1.9.2.7-rtn-r5066-MIPS32r2.tgz, corrected fstab, restored the files from the archive back, and reboot the router... ext4 partition is not mounted and is not displayed in the mount, df -h, and ext4 support in /proc/filesystems appeared. In what may be the reason that the section is not mounted? (

Router Asus RT-N16 c iOS 1.9.2.7-rtn-r5362. Some logs:

Does not mounted. Maybe have more some logs what I should to see? :(

Maybe in this case the reason is the same as described wpte, here (http://wl500g.info/showthread.php?18004-New-oleg-firmware-version&p=255515#post255515)?
