I use a acer aspire one netbook.
Everything was going fine until I updated my OS from 9... version of Ubuntu to 11.04. Since then my wireless internet connection keeps disconnecting and I need to restart my system everytime when this happens. I re-installed the broadcom wireless driver twice already and the issue still exists to bug me. I have a dual boot with Win XP and the wireless works fine on that, so the question on whether the problem lies in my wireless router is ruled out.
Can you please help me with this...
