My problem is that I am unable to discover new wireless networks using the network manager. There is no option to do so under tray, and System > Preferences > Internet and Network > Network Connections, yields only previous connections, as shown here: screen shot of Network Connections window
Wifi connects automatically to previous wireless network connections (on one now), and can detect new networks from
nmcli . When restart in presence of new wireless network (e.g. at coffee shop), I get a popup in top right that says “wireless networks are available” but no option to connect.
It really just seems like there is no direct way in Bionic Beaver/MATE to open the list of available wireless networks, because I did not have this problem prior to upgrading from Ubuntu 16 (which is where the network connections I do have came from) and I can connect to old networks Wifi automatically and/or discover new networks via command line. I’m sure this is something simple that I am missing, however I am new to Linux/Ubuntu and would appreciate any input.
I am running Ubuntu 18.04.1 LTS MATE 1.20.1
