Perhaps I'm on crack, but I've never encountered a MAC address of the format "127.0.0.1". That is typically known as an IP address. A MAC address is the physical ethernet address of the card. It typically has a format like: ether 00:d0:09:1e:be:04 While some cards allow you to change the MAC address, and this is certainly a problem for networks which use MAC-based authentication, I don't think that's what you were doing. -gabe On Mon, Aug 0 , 2001 at 05:21:08PM -0400, Russell Handorf wrote: > Traditional authentication with wireless lan's consist of the following > simplified procedure: > 1).
