Below are the screenshots. Notice that Asus signal strength is better (-70dBm). Oleg is almost unusable (-85dBm) - even though "radio power" is 19 in oleg but only 17 in asus! Why:confused:

Here´s asus 1.0.1.2 (I´m "WATERGATE"):
Signal strength ~ -70dBm
http://lh3.ggpht.com/_3jWLaYnz7tw/TF...2/asus1012.jpg

And here´s RT-N16-1.9.2.7-rtn-r1867:
Signal strength ~-85dBm!!!:confused:

Also a speed difference

Here come some poor observations and surggestions from a noob. :)

I see that asus 1.0.1.2 has a speed of 65 and the RT-N16-1.9.2.7-rtn-r1867 a speed of 54.

Is this due to the difference in signal strength?

Have you tried to measure the strength with another computer/network card?

1. Don´t think so - Oleg was configured G only. Maybe that´s it - cause I tested again with asus 1.0.1.2 also G only and then it measured 54. Still stronger signal though!
2. Yes - tested with another laptop (different brand) AND my PS3. Same result...

Best would be if someone could install 1.0.1.2 and confirm if they also get stronger signal....

speed is the (maximum) basic rate measured if I'm correct...

I'm wondering though... why G only?
if you set wireless mode to auto everything is supported :rolleyes:

Here I can still use internet at 50m distance trough trees and walls.
moreover, turning the wifi power up doesn't necessarily increase the network strength

Well - I just tested all possibilities to see if anything would increase signal - and it didn´t, so I just happened to make the screenshot at the "wrong time":o
Nevertheless - I still have lower signal with Oleg than with Asus firmware. Same settings...

With Oleg Firmware (RT-N16-1.9.2.7-rtn-r1639) the wireless signal is only good in the same room - but with Asus Firmware (1.0.1.2) I have strong signal everywhere in my house.
Just to confirm the settings:

This is with Asus firmware 1.0.1.2:
# nvram show | grep power
size: 18028 bytes (14740 left)
wl0_radio_power_x=17
wl_radio_power_x=17

And this Oleg:
nvram show | grep power
size: 14159 bytes (18609 left)
wl0_radio_power_x=19
wl_radio_power_x=19

Everything is default values (factory default after installed).
I have tried other values (30, 50 and even 84) but no big difference!

Is there something wrong with how Oleg handles the three antennas on the N16 - since stock Asus 1.0.1.2 has strong signal and Oleg VERY weak?
I´ve also tried Asus 1.0.1.6 (found on their FTP) and this was ALSO weak signal!
Can somebody check and confirm this?

Quoting myself just to show what I´m referring to
I´m a total noob at this - so I do not know how to check - BUT can there be something with MIMO settings for the antenna?

in the nvram you can change:

Quote:

wl_mimo_preamble=mm
wl0_mimo_preamble=mm

(standard)

moreover you can do some advanced settings with the wl command. (see attachment)

I don't know much about this, so you can break it, or you can make it:o

The last command in the "wl help" looks very interesting:

Quote:

mimo_ss_stf
g/set SS STF mode.
Usage: wl mimo_ss_stf <value> <-b a | b>
value: 0 - SISO; 1 - CDD
-b(band): a - 5G; b - 2.4G

If that value is set to 0 (SISO=single input/single output) then RT-n16 would use only one antenna, right?
Am I the only one with weak wireless signal (with Oleg firmware - Asus stock is normal)???

From your inSSider screenshot I can see that you use different security settings for Asus and for Oleg FW. Try to set up Oleg FW with WPA-TKIP, like it is set in Asus FW.
Just suggestion ...

Been there, done that! I have tested all settings - Asus outnumbers Oleg in signal strength...

Is there any possibility to ad IPTV settings in Oleg's Firmware for Asus RT-N16. Because original Asus FW already has that support, but original Asus FW sucks.

The legacy firmware code sets tx power in mw units, but asus doesn't set tx power at all.
moreower, radio power in ranged in 1 - 1496 mw, not in 1 - 84.
so, check tx power on asus firmware with

Code:

wl txpwr1

and set the value on 1.9.2.7-rtn with

Code:

wl txpwr1 -q qdbm_value -o

keep in mind, qdbm_value is ranged from 1 to 127.

my current values:

Quote:

[admin@rt-n16 root]$ wl txpwr1
TxPower is 127 qdbm, 31.75 dbm, 1496 mW Override is Off

I think they're thinking about the web-admin page wireless-advanced

Quote:

The Radio Power should be between 1 to 84. But default value is recommended.

so when I do

Code:

wl txpwr1 -q 127 -o

it should apply directly?
I haven't seen any difference:confused:
22-08-2010, 13:14
Magna-Flash

Ok - made some tests...

Asus 1.0.1.2:
TxPower is 127 qdbm, 31.75 dbm, 1496 mW Override is Off

Oleg:
TxPower is 51 qdbm, 12.75 dbm, 19 mW Override is Off :eek:

The GUI setting of Radio Power only allows a value of 1-84. 84 entered in GUI gives:
TxPower is 77 qdbm, 19.25 dbm, 84 mW Override is Off

So - the GUI value configs the mW´s... But if Asus 1.0.1.2 defaults to 1496 mW - why can´t you go more than 84mW with Oleg.

PS. Tried the wl txpwr1 -q qdbm_value -o but nothing ever happened. After reboot it was back to 19mW:confused:

time for some more #ifdef then I guess:)
this is a minor bug because of the new wl and how it works, should be an easy fix:D
Probably the best way is to set the bdm value in the web-config instead of the milliwatts, to make it look more obvious compared to the WL models.

LAN to WAN, WAN to LAN throughput

Hi,

what is maximum LAN to WAN and WAN to LAN throughput on latest Oleg's firmware for N16?

I'm thinking about replacing my WL-500G Deluxe because of low WAN-LAN throughput (25Mbit/s only - 100% CPU usage). My candidates are N16 or Netgear WNDR3700. N16 has about 140 Mbit/s throughput in both directions with stock firware, but WNDR3700 has about 400Mbit/s!!!

qdbm = dbm*4, not more not less, used for fine tuning without fractional part.
according wiki page http://en.wikipedia.org/wiki/DBm, we have

Code:

26 dBm 400 mW Access point for Wireless networking 20 dBm 100 mW Bluetooth Class 1 radio, 100 m range Typical wireless router transmission power. Maximum output power from unlicensed AM transmitter per U.S. Federal Communications Commission (FCC) rules 15.219.

wl driver has limitations 0-1496 mW, or 0-31.75 dBm, so switching to dbm would be wrong, 29 dBm is 794 mW, but 31 is already 1259 mW.
so, i would allow mW range up to 400 mW (26 bBm) with 50 by default (17 dBm).
current hardware wl adapter defaults will be used, if power value is 0.

any suggestions?

Yes, dBm and qdBm might be confusing both hence they are both based on a logarithmic scale, I was caught up with something when writing that:o
So it might be a good idea to stick with milliwatts, if it's mentioned on the web-config
If I recall correctly FCC allows a maximum of 1000mW when using 6dB antennas, so I guess it's a good idea to stay under that value by default:)

And the hardware default is the maximum possible value?

I'v changed my mind, dBm is here, and restricted with 1-31 range, 17 dBm (50 mW) as default with proper dBm units hint.

Looks like, last wl driver for 2.4 kernel does the same, and asus fw doesn't change it ever.

Great!
So - to get 1496mW (like Asus stock FW) I just enter 0 as value (in GUI)?

EDIT: Saw your post about going for dBm instead! Even better!! :)
Cause I want to transmit strong ;)

yep, but don't forget that with the higher tx power you'll get the higher level of noise, and your real connection speed could degradate
23-08-2010, 12:31
Magna-Flash

Entered 0 in GUI (Radio Power) and got:

[admin@WL-******** root]$ wl txpwr1
TxPower is 127 qdbm, 31.75 dbm, 1496 mW Override is Off

However - still pretty weak signal compared to Asus 1.0.1.2
Maybe this has something to do with it:

[admin@WL-******** root]$ nvram show | grep power
size: 14992 bytes (17776 left)
wl0_radio_power_x=17
wl_radio_power_x=0

Shouldn´t they be the same? In Asus 1.0.1.2 they both are 17 (wl and wl0):

# nvram show | grep power
size: 17662 bytes (15106 left)
wl0_radio_power_x=17
wl_radio_power_x=17
# wl txpwr1
TxPower is 127 qdbm, 31.75 dbm, 1496 mW Override is Off

Here are two screenshots - one with Asus FW, one with Oleg FW.
I entered the settings in each screenshot. Note that Asus is about 15dB stronger than Oleg. Same position of laptop/router (2m distance)

I don't think I mentioned this before, not sure if you've tried though.
have you tried changing regulatory modes: http://code.google.com/p/wl500g/wiki...egulatory_Mode ?

I'm not sure if the original asus firmware uses 802.11d standard.
I have original FW fobia these days:p

there must be an explanation for this, I mean the power levels are the same and they use the same driver right:confused:

The power values are NOT the same (look again;)) - that´s why I posted the screenshots.
I don´t know the difference between wl and wl0, but in Asus FW they are the same (both 17) and independent of the txpwr1 value.

However, in Oleg FW wl seems to follow the Radio Power value set in GUI.

ex.
A value of 0 in the GUI results in 1496mW txpwr1 and 0 in wl_radio_power_x.

So - my point is, the difference in signal strength maybe has to do with this?!

Re: WAN to LAN and LAN to WAN throughput

Thanks,

I saw the benchmark for Netgear WNR3500L, which has almost the same hardware like Asus RT-N16 (Asus has 128MB RAM, 32 MB flash, Netgear only 64MB RAM, 8MB flash), and WNR3500L throughput is 256/301 Mbps (WAN to LAN / LAN to WAN) with stock firmware. So the probably hardware minimum throughput for Asus should be the same as Netgear one I think.

Nope, it's just a asus stock fw bug...
Please, make sure you're using the same meaningful nvram settings

Code:

nvram show | grep regulation_domain nvram show | grep country_code nvram show | grep reg_mode nvram show | grep maxpwr nvram show | grep pwrsave nvram show | grep mimo_preamble nvram show | grep antdiv nvram show | grep txant

and, afaik, original one runs modern wl driver than we have in our

Code:

$ wl ver 5.10 RC56.46 wl0: Jun 18 2009 13:55:48 version 5.10.56.46

The only value that differed was reg_mode (d in Oleg, OFF in Asus).
I however set it to OFF in Oleg aswell to test - but no difference, still weaker signal.
Neither Asus or Oleg showed any values in these:

Code:

nvram show | grep maxpwr nvram show | grep txant

Downloaded the newly released Asus 1.0.1.7 and I also get weaker signal with that one!:confused:

hmm... perhaps it's just the different version drivers?

to be honest, the new settings made my wifi more stable.
for my wireless ethernet bridge (a WL-500W) the signal increased to -60dBm while it used to be -70
Average ping decreased from 4ms to 2,5ms and the package drop is 0% instead of 3%:p
Jitter is now 1ms instead of +40ms

So overall, that's great for streaming movies (what it is intended for), and now I don't need to drill a hole trough the ceiling for a utp cable:D

btw, I haven't had any wifi dropouts since I increased the wifi power:D

Which version of FW do you use and what is your power setting for movie streamig? I have a lot of problem with 1080p movies, especially at highest bitrate - it stucking.

I use it like this:
Internet <--utp cable--> [RT-N16] < - - - - WiFi - - - - > [WL-500W] <--utp cable--> [asus oplay]
This gives me a bandwidth of 40Mbits/s

with a wificard in my laptop I'm only able to pull 20Mbits/s which is more or less the problem of my laptop motherboard:p

If I put the same wifi card in my big PC I can't really see any difference in speed with cable... I'm able to stream HD perfectly.

I'm using this firmware atm: http://wpte.kicks-ass.net/downloads/...-rtn-r1967.trx

Thank's for reply. My problem is probable just one RT-N16 router which is WiFi connected to Xtreamer, so signal is not so strong in that case. I think so ...

using a wifi usb stick on the xtreamer then?
My O!play air has build in wifi (via usb as well actually) and it was just unacceptable... the player became unresponsive to the remote while playing and everything + no hd streaming whatsoever.
That's why I hooked it up to my old WL-500W which works highly stable now, but in the end: a little cable is always the best.;)

streaming from samba works fine, but I usually use upnp since it works (noticeably) faster.

Yes, samba is default for sharing files, but I use NFS, which is faster and more stable, but not enough to stream 1080p without the problem.
