How to view previous inputted MAC Address for WiFi network I have a Belkin Router and accidentally changed the MAC Address for the Wireless Area Network. Is there a way to retrieve previous inputted MAC Address using Terminal?

I'm looking around system and network logs but I can't find previous records of MAC Address for my WiFi network.
I think by restarting your machine its MAC address will restore to its original value. If not you can get your hardcoded MAC address by executing this command in the terminal:

networksetup -getmacaddress [your network interface, e.g. en1]
