Okay, so I recently purchased a Motorola WR850G Wireless Broadband Router. Along with that I have a Motorola WU830G Wireless USB Adapter. When I enable encryption on my router I am able to connect fine with the several PCI Wireless cards after I have entered their MAC addresses into the router (so it only accepts them), but when I try to enter the USB Adapter's MAC address it says that it is "illegal." What is up with this!?! It recognizes the USB Adpater's MAC Address when my router is open with no encryption and I am able to connect fine. I have also lowered the encryption for the USB Adpater so everything should be working fine, but this **** "illegal" thing has me puzzled. I've contacted Motorola and their reply was "Why don't you try searching Google!" I've already tried that, dumbasses. Anyway, help would be extremely appreciated. Thanks!
