The wireless was working fine under 18.04 and earlier LTS's, but at some stage became intermittent (dropping out at 4am for example) and needing a reboot. Upgraded to 20.04 and it worked for a short time but then failed and has never worked since.By 'not working' I mean the device driver is not loaded correctly so the wireless card is not seen by Linux which means nothing can be done through it. Ethernet is fine. I've googled and seen many solutions which don't work for me (re-installing network manager for example). Any help appreciated. It's a relatively old Gigabyte NUC GB-BXi7-5500
[update on booting under 16.04 added at end]
