I want to switch from my free usb modem (Efficient Networks 4060) that came with my bellsouth fastaccess service to an ethernet model (Efficient Networks 5250.) However, when I try and connect my pc to the 5250 I can't connect to my dsl service. Is it possible that this model has a mac address that I must register with BellSouth before it can work with my service? If so, how do I get it? Thanks for any help.
