When I installed Ubuntu on an HP laptop recently, I got a message that I didn’t have the drivers for my internal Intel wireless chip. It was at this point that I realized the laptop also didn’t have an Ethernet port. The installer told me to put the drivers on a flashdrive. Thankfully the error spelled out enough for me to find the drivers online. There were a few different versions and I put them all on the stick.

Bluetooth didn’t work, but I realized that was fixed by just enabling the service with systemctl.
