The wireless card is 'Centrino Advanced-N 6205 [Taylor Peak]' in ThinkPad T= 520. Its probably not 'em' driver related but I left it there because these are = the commands that I actually execute. The MAC in the above script is generated (but with first three octets from = real OUI). Regards, vermaden --=20 You are receiving this mail because: You are the assignee for the bug.=
