I'm having the same problem. In other versions of Ubuntu that does not happen to me.
Whenever I connect will my network wireless the connections is lost past few seconds and I must restart my router to have active network.
My wireless card is the same as your and my router is DD-WRT firmware.
I think the problem has to do with the wireless card, because with cable connection everything works fine.
