I occassionally visit a friend who has a WiFi network with MAC filtering. He has his mini-pci card MAC address on his WiFi Router. He won't enter my MAC address on his Router (he's had so much trouble he won't change anything!) but will tell me the MAC address he uses. Can I mimick his MAC address on: my mini-pci card, PCMCIA Netgear card or USB Netgear stick?
