From within the Mate terminal I entered: nmtui which opened a window which gave me 4 options, the second one to activate a connection which I pressed. This opened a window which said Wired connection 1 and below that was the name of my ESSID name I chose my ESSID and it said connecting a few seconds later it said could not activate connection activation failed. The wifi network could not be found. -- <dhoffjr@att.net>
