			In Linux, joining a wifi network automatically, or from the command line, or otherwise without a visual desktop, is not a trivial task - even in 2017.

			This page contains some notes on a few techniques for connecting to wifi networks, developed from experience with Raspberry Pis and other Linux computers with wireless devices built in (mostly laptops/virtual machines).
