I have a fresh install of ubuntu 12.04 on my Thinkpad T400. Everything works fine except wireless connection.
The problem with wireless connection is that my internet stops working ever 2-3mins (even though I still seems be connected with my wireless connection). My internet starts automatically after 2-3mins
Based on some of the suggestion on similar problems I have done following already
1) Set IPv6 to ignore 2) Power Management was set to off
But no luck with above two steps...
Any help would be highly appreciated.
