I've recently returned to the openSUSE fold after a prolonged absence. I installed openSUSE Leap 15.1 and, when at home, was able to connect to my home wifi network.

I took my laptop to the office so that I could get it to perform all necessary updates during the day but am unable to connect to the office wifi - either the secured or the open networks.

The default network manager can see the networks and appears to have a good signal - solid blue bar above the signal strength indicator. Unfortunately, this is accompanied by a yellow question mark. I can click on the signal and select the network. I get a 'Configuring interface' message below the chosen network, then it stops and 'Never used' appears below the network.

I'm pretty sure that there's a simple solution - but I cannot for the life of me find it.
