Find your wifi adapter mac address without ifconfig

Tuesday, June 11th, 2019

In the latest version of Ubuntu (19.04), ifconfig is not installed by default anymore.

If you need to find your wifi mac address while you have no network connection, you cannot install ifconfig so you need a different way to find your wifi mac address:

Do `cat /sys/class/net/<network_connection_name>/address` to display the wifi’s mac address.

On a default installation, <network_connection_name> is most likely wlo1. If it’s not, use tab completion, in all likeliness there are only three files in the net folder: the wired network adapter, the wifi adapter and the loopback address.
