BleepingComputer.com: Internal Wireless Card

Hi

Currently have a internal wireless network card that I use to connected to a router in the next room. I have just started to use this, as I was using a netgear USB wireless connection to connect to the router, to cut a long story short I want to use the internal card.
I can connect to my wireless network however it only stays connected for approx 10 minutes. I have the standard aerial connected to the router and internal card, and am wondering if by purchasing a new bigger aerial if this may solve my problem.
If there is anything else you can recommend me trying first please yell out!!!



thanks :D
