Update Kernel 3.3.0-4.fc16 breaks Intel Wireless-N 1000
Last modified: 2012-04-03 20:33:27 EDT
Description of problem:
The updated Kernel 3.3.0-4.fc16 breaks connectivity with Intel Wireless-N 1000. I am able to connect to my W-Lan (WPA2-PSK) but after 10-20 seconds it disconnects and reconnects normally again just to disconnect again. This cyclus keeps repeating as long as the Device is active.
In the time the connection is actually connected it works normal.
It works without (significant) problems under Kernel 3.2.7-1
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Boot kernel 3.3.0
2.Connect to WPA2 protected Wlan
3.Observerve continued disconnects
Unstable and unusable Connection.
Stable connection like in Kernel 3.2.7
lspci -s 03:00.0:
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000
P.S.: This is my first Bug report so it is probably not so well made.
Can we see the output from 'dmesg' after a few disconnects?
Have you tried using the 'wd_disable=1' option when loading the iwlwifi module?
ok just discovered one oddity:
It seems to only occur when I use the Speedport W722v at my girlfriend's place, while the Speedport W701v at my home works fine.
So the problem Is still that with 3.3 the connection is unstable but that is Access point dependent.
The bad part: it will be about 2 weeks before I can reproduce the error to cap dmesg.

dmesg output after 6 reconnect circles
This is the dmesg output after 6 reconnect circles. The module iwlwifi has not been loaded with special options.

dmesg with one additional circle with wd_disable=1
This is the dmesg output after the iwlwifi module has been reloaded with wd_disable=1 and one reconnect circle has happend.
I attached the requested output. Reloading the module with "wd_disable=1" did not change the reconnecting behavior.
ok the kernel version 3.3.0-8.fc16.x86_64 fixed it.
OK, thanks for letting us know.
