Make sure the pin on the BNC connector is not bent or broken. It could be a faulty antennae if you just purchased it I would be asking the manufacture for some explanation. I have not had the privilege of using an onboard wi-fi card accept in laptop applications. I do however know that performance between two different cards can vary tremendously depending on the distance between the router and the card and the obstacles between them IE: walls, windows, and electrical wiring. Also your cordless phone will cause interference too depending on the wireless technology.
