New MT and lots of new Problems

Sun Feb 11, 2007 12:28 pm

Hello
I started me new MT becouse me last mt (2.8) is too slow and sometimes get creazy :) So i think its time to change for new version 2.9 and new hardware P4 1.8 and new wifi cards:
Wlan1: Ubiquiti SuperRange 2 (SR2)
Wlan2: Senao NMP-8602-PLUS-400
But when i started this new MT i get lots of problem (I have last version 2.9.39) this is me problem:
1. Strangely "Signal Strenght (dBm)" < look the screen shot
2. Problem with negotiatiate good link speed like 5.5Mbps (On old Mt have no problem with negotiate 11Mbps here is problem with 5.5)
3. And old problem with "Data extensive loss" in log and other like this:

12:27:12 wireless,info 00:00:00:00:00:00@wlan1: disconnected, got disassoc: sending station leaving (8)
12:27:17 wireless,info wlan1: data from unknown device 00:00:00:00:00:00, sent deauth
13:38:22 wireless,info 00:00:00:00:00:00@wlan2: disconnected, extensive data loss
13:38:34 wireless,info wlan2: data from unknown device 00:00:00:00:00:00, sent deauth

Hi, I'm having some of that problem.
I'm using MTK APs with Edimax Clients and I get a lot of disconnection messages.

I'll post results then.

Thanks.

Try to change antena a or antena b in wireless config. Maybe you select wrong antena on wireless card.

Which channels are you using? TX power? How close are antennas to eachothers?

Replace the senao radio with an R52.

The router board with the senao is flaky in many different ways.

hy,
in your first screen shot , you can note that your signal to noise is 61 dB, ... I think that this is too high.

Try to search a channel with noise floor around -88/-90 on the wlan2, maybe this can solve your disconnections.
