Dell 7480, new to Linux. I installed Ubuntu 20.04 along side Win10 and it seems to work except for the Wifi in Ubuntu. Secure boot and Fast startup are disabled.
I thought it was only problem when I did a 'restart' instead of a 'shutdown' from Windows (where Wifi always works), but that isn't the case anymore. It worked for a while though, so I've used Wifi in Ubuntu many times. It also worked fine running live from the USB. If I have a network cable plugged in when I boot Ubuntu then remove it, the Wifi works.
I think I saw something about this type of problem somewhere but can't find it anymore. I ran these commands/diagnostics:
sudo lshw -C network
