Ubuntu – No ethernet connection available in Ubuntu 20.04

driversdual-bootethernetinternetnetworking

I just installed Ubuntu 20.04 on a clean SSD alongside windows to do C development and when I first booted, there was no internet connection yet my ethernet worked perfectly in windows.

My network controller is the realtek RTL8125 2.5 gb and is labelled "UNCLAIMED" when I run the lshw -C network command. I can access the internet using a USB tether to my phone but nothing I have tried so far has fixed the problem.

Would appreciate any help

i had the same exact issue. i was missing drivers for the Ethernet.

Go to Realtek site from the actual Ethernet provider. Download the "2.5G Ethernet LINUX driver r8125 for kernel up to 5.6" and follow the install instruction.

You should be able to use wired connection once your done.
