I saw earlier you mentioned it’s an Optiplex, so I’m assuming this is an onboard NIC.
I’ve never had an onboard NIC not work out-of-the-box in Linux. Wifi, sure, but usually just certain chipsets with proprietary/closed firmware. Dell usually uses Intel NICs and they’re usually pretty solid and well supported.
Check to make sure that the NIC is enabled in BIOS.
If you have/had Windows on this PC, did it work there?
Does the NIC show in lspci
or ip a
?
Try an external USB NIC. Or an internal PCIe one if you’re comfortable with that.
I managed to find Extra History via Nebula, and it’s one of my new favorite channels…but I’ve found a lot more favorites from YouTube, definitely.
One thing I do love is finding a new channel I like that has years of backlog.
