Comment 1 Stanislaw Gruszka 2012-10-16 10:38:15 UTC 
Please add this iwlwifi module debug option:

echo "options iwlwifi debug=0x0803" > /etc/modprobe.d/iwlwifi.conf

and install this kernel, with additional patch:

http://koji.fedoraproject.org/koji/taskinfo?taskID=4591540

Then try to reproduce the problem and provide output of dmesg:

dmesg > dmesg.txt

(attach dmesg.txt file here).
Comment 2 Stanislaw Gruszka 2012-10-18 11:42:18 UTC 
Please test this kernel (with proposed fix for the problem) and report back:

Comment 5 Edouard Bourguignon 2012-10-18 16:38:45 UTC 
It's working very well now with this test kernel. Before I had ping loss just after AP association, now it's fine, and ssh connections don't lag anymore! Thank you!
