With kernels with a version greater than 3.8.12 I can't connect to my university's WIFI (eduroam: https://www.eduroam.org/) anymore. Networkmanager just times out after 90 seconds.
My wifi-card is:
Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)
With kernel 3.8.11 or older it works with the same userland.
I've tracked down the issue to commit 63b77bf489881747c5118476918cc8c29378ee63 (http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/net/wireless/iwlwifi/dvm/sta.c?h=linux-3.9.y&id=c30f37f8f1f8d06c142d67ba74955fd48b5cf5a4)
If I revert that patch it's working fine again. Therefore I'd guess that it's a regression on the kernel side.
can you please send the logs of the driver?
please load with debugs:
modprobe iwlwifi debug=0x1001
Is there an easy way to enable debugging if I'm using a monolithic kernel?
I don't really see how...
you can play with the code to enable debugging hard coded...
You also need to make sure that you have CONFIG_IWLWIFI_DEBUG set
Pass "iwlwifi.debug=0x1001" on the kernel command line (without the quotes)
Actually, the parameter should also be writable in sysfs:
echo 0x1001 > /sys/module/iwlwifi/parameters/debug
(if the file doesn't exist, you don't have CONFIG_IWLWIFI_DEBUG set)

log with commit reversed: NetworkManager works
I've attached two logs:
The first is with the problem. NetworkManager can't get a connection and times out after 90 seconds.
The second is with essentially the same kernel but the commit reversed (via patch -R). Connection is established and works well.
Note: in both cases there is a connection to a open WIFI before trying to establish connection.
Command used to establish the connection was is both cases:
nmcli con up id <networkname>
I am afraid I will need a bit more logs:
Please send again a working scenario along with a failing one.
Here are the log - due to size constraints I've uploaded them externally:

fix for EAP
please try the attached patch
I can confirm that your patch fixes the issue for me.
I am still having this problem.
I applied the patch on gentoo-sources linux kernel, 3.9.4.
I use wicd.
can you try 3.9.6?

> can you try 3.9.6?
Ok, it seems to be OK with it. At least for the first attempt (after the first reboot with the new kernel).
Thank you for the suggestion.
