The motherboard that I?ve got is an Asus P5W DH Deluxe, and it comes with a wireless antenna built in. Recently though I got a new router, the Belkin Pre-N, and a new wireless card to go along with it since everyone said you really needed both of them to really unlock the potential of the Pre-Niness. Prior to installing the new card on my desktop, I uninstalled the drivers for the MB antenna, but lately I?ve been wondering, what would happen if you had both going at the same time? I know it sounds like a weird idea that would probably just result in Windows getting confused and the two antennae running interference on each other?s connection, but has anyone ever tried this? Does anyone know what would happen?
