You must be connected for this to work. 1. do a 44 from the applications menu. This opens up the network manager. 2. select the network to which you are connected with the up/down arrows. 3. press the options key, or do a ctrl-o. This opens the options menu. 4. select 1 for details. 5. use up/down to select mac address. I think it is the first selection. This will be a 12 digit hexadecimal number. Good luck.
