[TriLUG] Updated to Ubuntu 20.04 and no wifi

[Matt Flyer via TriLUG]

Saying module not found to suggests that the driver may not be
installed.  See this link: [Solved] WiFi not Working in Ubuntu Linux
(itsfoss.com) [1] 

Apparently this is a big problem with Broadcom cards, but others as
well.  You will need a network connection, such as a wired, and then can
check for"additional drivers" under software & updates. 

Maybe you'll get lucky and it's an easy fix.
