Connecting to Eduroam is something we managed a workaround for a little while back, but wasn’t a massive priority as we usually use Ethernet (and didn’t want to upset university IT too much!). From memory the trouble comes from interactions between the current version of raspbian-openflexure and wpa_supplicant with Eduroam - I think it’s possible to install Network Manager* on the Pi and then disable wpa_supplicant to allow it to take over, then login as normal. @JohemianKnapsody am I remembering this correctly?
