I installed Ubuntu Server 20.04 on a spare laptop. Long story short, it did not have any way to connect to my WiFi network unless I either first went through the guided installation with an Ethernet cord attached, or went through some excruciating troubleshooting steps involving setting up hardware via obtuse CLI commands and arguments. I tried the latter just to see if I could without looking things up on my phone/separate computer, and even with a bit of cheating I still gave up and tried again with the cord plugged in.
