WiFi Working, Wired connection not.

[John McLovin]

Yesterday I wanted to move from Windows 10 to Linux (again) but I had bad luck I guess with the network-manager and its current version.

My WiFi is working without any problems but the Ethernet (wired connection) is not working. Tried (installed and fully updated) Pop OS 20.10, Kubuntu 20.10, KDE Neon based on 20.04 same problem on all of them. Not working from Live USB too. Went back to Windows 10 - everything works without any problems.

Tried some debugging: taking out the cable and plugging it back. No luck.
Restarting the laptop - not working.

Laptop model Acer ES1-512 if it matters.

On network, I have Broadcom and Atheros - not sure which one is for the ethernet.

P.S: Whine Kubuntu was loading (the text window) I saw with red Failed - network manager online or something like that, can't really remember the whole thing.

sounds also more likely a kernel issue than a network manager service one
