Ok, this is my situation: We have, or will soon have 2 PCs and 1 Mac that I need to hook-up to a wireless network where all 3 computers can be online at the same time. My question is, what company makes the best wireless routers that will work with the Airport Extreme card? I am soon ordering a new iMac and I figured having an Airport card installed is a lot easier than having an external reciever. I have recently heard that Belkin and Linksys are the best and that Netgear and D-Link arn't that good. Is that true? And is there a difference in speed between a USB adapter and a PCI card to recieve the wireless signal?
