If I close the lid to my computer and leave it for a couple of hours. Ubuntu prompts for password again when loggin on again.
Password is already filled in and is correct.
It doesn't happen if I just close the lid and immediatly opens the lid and logs on again though.
As a work around I restart network-manager and the wifi resumes in a couple of seconds.
I'm running 12.04 and this affects me aswell.
