I’m a new user of Ubuntu MATE. Installed 16.04 LTS from de DVD, got my wifi working and have been happy and very content user since a couple of weeks. Then last week got the message that there were updates. followed instructions to install them and now my wifi isn’t working anymore. Cannot find the info to get it working again and would appreciate your help.
Read that I needed to do following command, but after that I’m lost.
