BleepingComputer.com: Damn Wireless! Or Is It Damn Vista?!?

Ok here is my problem:

A couple weeks ago I bought a new laptop.
It keeps cutting in and out with wireless. Sometimes it says "limited or no connectivity" but that always means it is about to cut out. Sometimes if I hit Refresh it will come back up right away but other times no. I have spoken to vorizon (my fios provider) and determined that there is nothing wrong with the router, plus all other computers are working fine with the wireless, including my super old laptop that needs an external card to connect.
It's a Acer Aspire with Windows Vista Basic.

Please help!
