WAN port dies - fixing speed

[Oleg]

We need some info on this terrible problem, so Antiloop as well as number of other guys have reported, that fixing port speed fixes the problem.
So, the idea is to prove this finally.

Anyway, please try to fix port speed to 100full, 100half, 10full or 10half. Try to find one, which fix your problems.

Please note, that fixing port speed will slow down boot-up for the first time. This is due to the fact, that partner on the other side of the link will need to determine port speed and connection type by itself.

Also, it's possible, that link will never be established (possible reason for that is dumb device on the other side). Wait several minutes before claiming "it does not work".

Another option, pereviously reported on the forum is that wl500g does not boot with forced speed - just disconnect WAN port cable and power off/on unit. It's safe.

Never happened to me.

Modem brand and type: Zyxel prestige 650R-31 (Analog ADSL modem/router).

Anyway, please try to fix port speed to 100full, 100half, 10full or 10half.

Do mean something like

wlanutil eth1 ethsetx speed 4

(100full, in this case)?

Try to find one, which fix your problems.

I have tried all possible speed settings and the wan port still dies after some time of heavy traffic. Interestingly, the transfer speed I experience isn't influenced by the speed I set with wlanutil.

wlanutil eth1 ethsetx speed 4

I mean changing it from web interface or with et utility by exusting something like this from the shell prompt, or Main_AdmStatus_Content.asp:

et -i eth1 speed 100full

Please re-test, it should have impact on performance.

I mean changing it from web interface

Well, this setting isn't available to me as my wl500g's "Operation Mode" is set to "Router" (my wan port is connected to another segment of my home network, not to an adsl modem or anything like that...)
Therefore I took a look at /init/ethernet

if [ -n "$x_ConnectionSpeed" ] && [ "$x_ConnectionSpeed" != "0" ]; then
        wlanutil ethsetx $1 speed "$x_ConnectionSpeed"
fi

and thought setting the Connection-Speed is done with wlanutil.

I'll post my results when setting the speed with the et utility after some tests.

Setting the speed to 10half, 10full, 100half or 100full with the et utility,
there were no crashes even after transferring a few GBytes of data.
Using the auto setting eth1 dies (and can be recovered with et -i eth1
promisc 0) after some hundred MBytes.

Test setup:
[pc2]-eth0 <~~~> eth1-[wl500g]-eth0 <~~~> eth0-[pc1]
pc2 uses a Realtek 8139C for the connection to the wl500g,
test traffic was created with netio-1.17

Well, Antiloop reported the same - any forced speed fixes problem for him. Added new poll option - any speed fix.

For me, WAN Port die issue only happen on downloading with BT. When the transfer rate reach 8xx KB, it MUST die within 5 mins. (My internet connection is 10mb/10mb VDSL) Actually I'm ASUS fan, but this product really makes me DISAPPOINTTED.

can you please confirm that you have tried all speeds and not only AUTO ?

e.g. when i'm testing i have 2,5Megabyte/sec download and then it does not die when using a fixed speed setting

try firmware 1.8.1.9, in that firmware the speed settings work from webinterface in earlier 1.7.x.x versions it does not work or not correctly

i tried to use 1.8.1.9. but the problem still occurr. So, i changed to use 1.7.5.9 cr-5 with the QOS. actually, it work if i limited in a slow speed. But i don't think that it's not a good way to fix the wan port die problem.

By the way, i'm very very appericate the working in web site. I'll try to
upgrade it back to 1.8.1.9 and try all port speed.

THANK YOU VERY MUCH

@ jcbos
can you please confirm that you have tried it correctly (e.g. with new 1.8.x.x firmware) to test if line dies when using a fixed speed ?

Man, It was a long one. I don't remember all that was put there. It is a pity because there was some good info there for helping to diagnose this problem. If I remember later I will try to post it again.

Here are the results from tests I preformed about two and a half months ago:

After I entered in telnet “et -i eth1 speed ....” (where the dots have to be replaced with auto or full10 or half10 or full100 or half100. I transferred up to 9 big files (+/- 700 MB from WAN to LAN using ASUS M3700N as FTP server on WAN side and a PC as FTP client on the LAN side)

et -i eth1 speed auto
RESULT: WAN dies in a few minutes

et -i eth1 speed full10
RESULT: after 20 minutes the WAN is still alive

et -i eth1 speed half10
RESULT: after 20 minutes the WAN is still alive

et -i eth1 speed full100
RESULT: doesn't work at all (WAN light doesn't even go on)

et -i eth1 speed half100
RESULT: doesn't work at all (WAN light doesn't even go on)

BTW: I have a 1120/352 Kbit/s internet connection connected with a SpeedTouch 510 an the WAN side

Hi, I've already tried setting the speed of my router but it still seems to drop off every now and then when I use BT. After it disconnects (PPPoE dropping off), I would have to do a manual disconnect then a connect and then do the et -i eth1 promisc 0 command to get the PPPoE connection back up again. I'm very annoyed at this and it would be greatly appreciated if a fix can be formulated for this.

I am currently using the 1.8.1.7-1 firmware.

I don't know if the following log would be useful or not, but these seems to be generated when my PPPoE connection dropped off.


Oct 14 14:46:03 (none) local2.notice pppd[2821]: Serial link appears to be disconnected.
Oct 14 14:46:03 (none) local2.warn pppd[2821]: Couldn't increase MTU to 1500
Oct 14 14:46:03 (none) local2.err pppd[2821]: Couldn't increase MRU to 1500
Oct 14 14:46:03 (none) user.emerg PPPoE: Disconnected
Oct 14 14:46:09 (none) local2.notice pppd[2821]: Connection terminated.
Oct 14 14:46:09 (none) local2.warn pppd[2821]: Doing disconnect
Oct 14 14:46:39 (none) local2.err pppd[2821]: invalid packet
Oct 14 14:46:39 (none) local2.err pppd[2821]: Failed to negotiate PPPoE connection: 9 Bad file descriptor


Also, I don't know if this is related, but sometimes, I get this line:

Oct 14 12:58:27 (none) user.warn klogd: ip_conntrack: table full, dropping packet.

can someone tell me what it is?

Thanks in advance
