Bug Description

Hi,

I installed Ubuntu 12.04 Desktop i386 on my Lenovo Thinkpad X61s.

Wireless is very very slow, quite impossible to do the updates, internet surfing very slow etc.

Regarding bug #1018423 I tested kernels 3.5 rc5 and 3.6 rc4 with no better result.

Thank you for you help on this very annoying problem.

I found this : http://forums.gentoo.org/viewtopic-t-910606-start-0.html

I tried the following :
1) create a new file /etc/modprobe.d/iwl4965-disable11n.conf with the following content:
     options iwl4965 11n_disable=1
2) Reboot

It seems to be a good workaround as I am now able to do apt-get update and install new packages.

I will try to remove the manually installed 3.5rc5 kernel.

Works well also with standard 3.2.0-30-generic-pae kernel from ubuntu repositories.
