After upgrading to linux-3.2.2-1, my wireless connection stopped working. It "connects", but I can't get an IP address through dhcp. Assigning an IP manually doesn't do the trick, I can't even reach the router through ping.
Downgrading to 3.2.1-2 fixes the issue.
I suspect this may be a regression but I couldn't find any information or reports of other people having the same problem anywhere.
I should note that I can establish a working connection when running the new kernel by using an external USB wireless device, so this probably has to do with the modules/drivers of my network card (?).
This is the ouput of some commands when running the new kernel (wlan1 is the device mentioned avobe):

You must not have searched very long then, because you've missed not one, but two threads:

I did search quite long in fact. But I didn't search in the forums, I used google.
Anyway, thanks for the links.
