Description:
On a fresh install of Linux Mint, I am connected to the internet through a wired connection. Even though the internet is working just fine, Linux Mint shows the network status as "cable unplugged." I am also receiving errors in Software Manager when trying to download a package that I am offline. I can use apt at the command line to download the very same packages without issues.

The laptop is a Thinkpad T490. Here are my system specs:

The "cable unplugged" part is weird. You have a fairly common and reliable I219-v chip, and since it is evidently working partially, my guess is bad cable, bad wire pair in the cable, or bad connection on either end.

Potentially? I've had this same cable plugged in for a very long time, it's never given me problems and Windows has never reported anything strange with it. Nonetheless, I can try a different cable and see if it helps.
