There is an upstream bug and a regession in the 3.x kernel. Some people have had luck disabling wireless n.

Depending on which driver you have, try applying this setting to iwlwifi or iwlagn, use lsmod to see which module is loaded for you.

Code: Select all

sudo rmmod iwlwifi
sudo modprobe iwlwifi 11n_disable=1


make it permanent by adding

Code: Select all

options iwlwifi 11n_disable=1

to .conf file in /etc/modprobe.d/
