Hi, I’m running opensuse 11.2 on my Asus 1000H, today I found the new kernel Kernek-Desktop 2.6.31.8 will cause system lock down when I try to connect to any wifi assess point. I updated to 2.6.31.8 from Opensuse-11.2-update days ago and today it’s my 1st time to try to connect to wifi with this new kernel.
Downgrade to 2.6.31.5 will solve this problem.

What wireless device?
It’s RT2860
I have the same problem with kernel 2.6.31.8 but I am using an rt2870. So downgrading the kernel worked for you huh? I’ll have to try that.

That driver had problems with power-saving mode. Is it helped with the command
sudo /usr/sbin/iwconfig wlan0 power off
If your device is not named wlan0, make the appropriate change.
I have the same issues here, my Netbook is an Asus EEEPC 1000 .
My wifi is the rt2860sta.
I solve this doing the kernel downgrade.
I upgrade again and try the “iwconfig wlan0 power off” , don’t supported.
I read the documentation of iwpriv: /usr/share/doc/packages/rt2860/iwpriv_usage.txt and there talk about the option PSMode.
There is no possible to view the PSMode status, but they permits change

I just can’t say if work because here on my Job don’t have any Net to try connect… at night I will test in Home and post here if this work arround works
Hi All,
after test the command:
, both still freeze the computer… so I downgrade my kernel, again…
Just for curiosity , with your guys, when upgrade the kernel your devices name change ? between ra0 <-> wlan , then in some upgrades back to ra0 … this is annoying and always happen with me…
In kernel 2.6.31.5 my device name is ra0 , in .8 is wlan0 , in version 2.6.29 is wlan … arrrrrrrrrrrg!
Yeah I notice the same thing with the wlan <->ra switch, although I haven’t tried 2.6.29. I noticed in the updates today there was a patch for the kernel but not an update to something like 2.6.31-9 just an addon patch to the kernel. Does anyone know where I could find the release notes for that see if this issue was affected?
