No network connection

All of a sudden there is no network connection using Wiley MATE. I was typing an email is Gmail using Firefox while downloading updates and computer crashes. I start up and log in and launch Firefox and computer crashes again. Then everything works normally. NOW I cannot get computer to connect via WI-FI. Why is my computer attacking me like this???


run “dpkg” per the update guide (a network cable connection is required for it to work!):
