RT73 recent problems

karabaja4 · 2009-11-24 07:46:54

Ok, something is really fishy here. My RT73 card:

[deadbeef ~]$ sudo iwconfig wlan0 essid my_essid
[deadbeef ~]$ sudo iwconfig wlan0 key s:my_password
[deadbeef ~]$ sudo dhcpcd wlan0
dhcpcd: version 5.1.3 starting
dhcpcd: wlan0: waiting for carrier
dhcpcd: wlan0: carrier acquired
dhcpcd: wlan0: broadcasting for a lease
dhcpcd: wlan0: offered 192.168.1.247 from 192.168.1.1
dhcpcd: wlan0: acknowledged 192.168.1.247 from 192.168.1.1
dhcpcd: wlan0: checking for 192.168.1.247
dhcpcd: wlan0: leased 192.168.1.247 for 1800 seconds
dhcpcd: forking to background
[deadbeef ~]$

So far so good. But internet doesn't work. Also:

[deadbeef ~]$ ping 192.168.1.1

On a same computer my atheros pcmcia card works with no problem (ath0):

[deadbeef ~]$ sudo iwconfig ath0 essid my_essid
[deadbeef ~]$ sudo iwconfig ath0 key s:my_password
[deadbeef ~]$ sudo dhcpcd ath0

And, I tried to compile rt73-k2wrlz-3.0.3, after some patching so compile would work on 2.6.31.6 - it connects beautifully on my RT73.

Why, are kernel-integrated RT73 modules broken or am I missing something?

I've done some unsuccessful bridge experiments on wlan0 recently, could it be that I left something somewhere, some option or hidden route for that specific interface?

What does iwconfig show after the ping fails?

So, judging by your replies, I'm pretty much doomed?

knedlyk · 2009-11-26 16:01:32

Could you try wicd or network-manager with wpa_supplicant? I had the similar problem, rt73 wifi card didn't work with the iwconfig commands, but worked perfectly with wpa_supplicant.

Strider · 2009-12-06 20:43:51

I do not know if this is related but my connection from my rt73 dongle to my wireless router seems to drop from time to time. It is most likely to happen after a certain period of inactivity (like it has to 'wake up). A ping to my router does than show times of more than 4 sec in the beginning which than drops to 0.5 ms after a few pings.
I tried to change channels but the problem remains. What it did do was set the power management to off (iwconfig wlan0 power off) and that gave a serious burst to my connection. Before that I had more than 2 ms ping to my router : it is now dropped to 0.5 ms. I discovered this by comparing ping under Arch with ping on Vista (my machine is dual boot). In Vista ping showed times of '< 1ms'.

But still my connection drops from time to time ... :-)

karabaja4,

how dit you get rt73-k2wrlz-3.0.3 compiled ? I'm also on 2.6.31-6 but it fails to compile ..

Problem miraculously solved by update to kernel 2.6.32. This confirms my suspitions that 2.6.31.6 kernel modules were somehow screwed up, at least for me.

@Strider, compiling rt73-k2wrlz-3.0.3 - http://forum.aircrack-ng.org/index.php? … 0#msg33360 (there are a few changes to code/makefile).

Strider · 2009-12-09 20:21:04

I updated my kernel to 2.6.32 also. My problems are MOSTLY gone now. I'll see if I can find some usefull options with my router which is wireless N while my dongle is wireless g. Might be a source of problems too
