Ubuntu – How to get the Lenovo T61 to connect to a wireless network


I have a Lenovo Thinkpad T61 and the wireless works just fine so I installed Ubuntu straight away only to find that the wireless will not connect, it will see the networks but just not connect. Has anyone managed to solve this all the forums seem to relate to Ubuntu 9.04 and before.

Edit:Sorry about that, I didn't realise that there were 2 models mine is the Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection. Any help is much appreciated.

If the machine is running 11.04 or 11.10 you need to disable "n" by running this in a terminal:

gksu gedit /etc/modprobe.d/options.conf

and adding this line to the file:

options iwl4965 11n_disable=1

Reboot and try to connect again.

Ubuntu 12.04LTS solves this problem (I will update if this changes).

Edit: So far versions after and including Ubuntu 12.04LTS do not have this issue with the Intel 4965 wireless card.
