Default Wireless card failing after a while

Hello All,

I've been having some issues on my IBM netfinity server toybox. For some reason the networkcard stops working while there is no apparent reason. Sometimes it happens during transfers, sometimes just while it's idle. In /var/log/messages I get the following notifications.

I'm using Debian etch and the RT61 drivers from ralink.

normal behavior is like this (/var/log/messages):

Jan 5 15:25:49 Netfinity kernel: a1:35:d0:01:7e:07:28:61:e0:5b:2b:82:ce:c5:aa:b8:

Jan 5 15:25:49 Netfinity kernel: 47:80:09:1d:cc:4e:6a:aa:
Jan 5 15:41:41 Netfinity -- MARK --


but when things go wrong I get the following:

Jan 5 17:25:55 Netfinity kernel: TxRing0 PBF=22222422, HwIdx=18, SwIdx[19]=00.00.00.00.DmaIdx[18]=00.00.00.00.d9:62:94:af:0e:30:33:58:ad:3f:09:a9:b c:f9:a9:fc:

Jan 5 17:26:05 Netfinity kernel: 89:74:56:fb:90:bc:01:b9:


and the above keeps going till shutdown.

Anyone any experience with this? I've used this card before in another machine with the same drivers and that machine didn't have any problems. Difference is that this machine is an SMP machine (2x 600MHz, 2GB Memory).

The card itself will remain visible in ifconfig, so it's not really going down, it just doesn't transfer anymore. When I do '/etc/init.d/networking restart' then the issue is resolved again.
To me it seems like he can't associate anymore with my wireless router, maybe because of an WPA (PSK/TKIP) issue?

Any help is appreciated.

Thanks,

Tom Raus

Could be -- under WPA the router will periodically change the encryption key --
this problem could be occurring when that happens, ie your card isn't resynching
to the new encryption key for some reason. Does your card support WPA? When you
used it before was your network using WPA as opposed to WEP?

On the machine where it was working properly before the same exact conditions
where true. It was the same network with the same encryption with the same
driver and the exact same operating system. That machine never had any
problems at all. It could be that it fails the sync but there is little I can
do about it. If I was better at scripting I could write a script that
restarts my networking devices (it's only a home server so it's not that big
of a deal).
