SOLVED Wireless stopped working in kernel 3.2.0.1 in Wheezy.

Postby Peppe » 2012-02-26 08:08

My Acer 522 has been running fine until the new kernel 3.2.0.1 was relesed to Wheezy.
Now, the wireless adapter AR9485 Wireless Network Adapter which uses the ath9k driver seems to work fine, it connects to the accesspoint and i get an ipadress but i can't ping anything my router or anything on the net.
If i revert back to the 3.1.0.1 kernel the wireless fine again.

So the real question if it's a bug in the 3.2.0.1 kernel or some thing needs to be changed to get the wireless working again.

I'll inclued some info when I ran the 3.2.0.1 kernel.

Re: Wireless stopped working in kernel 3.2.0.1 in Wheezy.

I also suffered problems with the wireless device (Atheros AR9285) after updating the kernel to 3.2 from Backports and from Testing a couple of weeks ago. That being said, I only have issues with WEP encryption; open networks or those using WPA work fine. Too bad that, as a laptop user, you'll never know when you'll need to connect to a WEP one.

This must be a regression. The error messages from my system are the same as those from yours. I also had to revert to the kernel 3.1, which, by the way, now loses the connection to WEP networks sporadically; something that didn't happen before updating to the kernel 3.2.

You'll find lots of messages if you search the terms "deauthenticating" "by local choice (reason=3)", but I found no definitive answer. Some say that you should disable IPv6, others that you have to kill wpa_supplicant, others that the problem is caused by Network Manager. I tried the first two options without luck and then chose to keep my applications and just use a previous kernel.

I have tried a usb wireless adapter and it is working fine with the 3.2.0.1 kernel.
So i suspect this is a bug in the 3.2.0.1 kernel and atheros and I'm hoping that this will be solved in a newer kernel in the future.

Thanks for the feedback!

Regards, Peter

EDITED:

It would seem that the latest update included a new kernel and the wireless interface seems to work now.
