iwl 4965 + WPA

Hello everyone!

I had an issue with my iwl 4965 failing to connect to my WPA protected network.
I read several posts regarding this issue on the forums, but none had found a solution.
Since I have one, I will post it here.
This issue was tricky, because it was hard to reproduce - it only happened when connecting to Pre N WPA protected wireless networks, which is my case.
Fortunately there is an option for the driver that can be passed during modprobe: 11n_disable=1
In order to test if it's working for you just do it the simple testing way:

# modprobe -r iwlagn
# modprobe iwlagn 11n_disable=1

Check if it works. If it does, just add the following to /etc/modprobe.conf to make it permanent:

#Make Intel wireless card work with WPA on pre N routers:
options iwlagn 11n_disable=1

Good luck.
I had a hard time finding this info, so I hope I can help other people by making it easier to find.

Oh, and BTW, this is also supposed to work on cards such as the iwl 3945 and other. As far as I know the issue should not be present on iwl 5100 and above...

Edit: Thank you,vi3dr0, for correcting the typos!

Re: iwl 4965 + WPA

There is a typo in first two lines - module name is iwlagn.

Wonder why my 4965 is just working without any issues

Re: iwl 4965 + WPA

I can say it falls back frequently to about 150 Kbps here though... I'll see if it helps any here, thanks for the hint.
