It used to be a hassle to get a wireless adaptor working with the Raspberry Pi. But these days both the Raspberry Pi 3 and the Raspberry Pi Zero W have one already on board, and getting wireless networking working is much easier.

The Raspberry Pi 3 already has an on-board wireless adaptor.

But what if you want to add a second wireless adaptor in monitor mode?
