I'm running Ubuntu 12.04 on a Compaq evoD500.
My computer randomly loses connection while the other computers in the house are still connected, so I know the problem is specific to my box. The other boxes are running windows XP.
I think Network Manager might be the problem and would like to try wicd, but I'm concerned that I might not be able to revert back to Network Manager if I need to.
Let me know if more info is needed. Thanks.
