How can I find the MAC address of my wireless card in Vista? I want to
limit access to my wireless router by MAC address.
The MAC address is printed on a label on the wireless card itself, or you
can go to the Command Prompt and enter IPconfig /all that will show you the
MAC of the wireless card used by the computer.
If you want to know the MAC address of the router, then it's on physical
label on the outside of the router somewhere in the area of the serial
number that's on a label.
