Aspire 5100 wireless problem

Hey,
Just bought me a brand new Acer Aspire 5100 and the wireless module is acting kinda funny. It just keeps deconnecting and reconnecting… Anybody got a clue?
I,m thinking it might be a driver problem, but I,m still at lost as to where to look…
I’m about to bring it back to the store… Deal or no deal, there *is* a limit… =)
Thanks
