Yesterday I bought a linksys AE2500 usb network adapter. So I set it up on the computer downstairs from the router, roughly 30 ft distance. There is a desktop running a linksys pci card directly next to it. So I fire the computer up it see's the network but it won't connect to it. Then I take the computer up to the room the router is in and it connects. The range on the adapter says 300 ft and I do realize that there are walls and other obstructions that cause that number to fall but I find it hard to believe that the adapter is out of range but I can't think of anything else to explain it. Anyone have any suggestions? Thanks.
