Comment 6 Wietse Muizelaar 2012-02-04 16:09:33 UTC 
I have the same issue, it started when I updated my Fedora16 system to kernel vmlinuz-3.2.2-1.fc16.i686.PAE.

On vmlinuz-3.2.1-3.fc16.i686.PAE; the system works fine.
Comment 7 Wietse Muizelaar 2012-02-12 14:42:07 UTC 
vmlinuz-3.2.3-2.fc16.i686.PAE and vmlinuz-3.2.5-3.fc16.i686.PAE work fine for me, so for me this isn't an issue anymore.
Comment 8 John W. Linville 2012-02-13 15:03:30 UTC 
Alexey, can you replicate this issue after upgrading to kernel-3.2.5-3.fc16 (or later)?
Comment 9 Jim Perrin 2012-02-13 15:07:34 UTC 
I am also seeing this issue with f16, on a dell e6420 laptop using intel 6300AGN wireless adapter. 

WEP and open wifi seem to work fine.
Comment 10 Jim Perrin 2012-02-13 15:08:29 UTC 
Sorry, using the kernel-3.2.5-3.fc16 kernel. I've not yet tried a more recent one.
