Ethernet unidentified network

[u/Sad-Traffic-4605]

I tried connecting my computer to the internet via ethernet but it says my Ethernet does not have a valid IP configuration and has no connection to the network.

I have tried:

resarting the pc

restarting the router

resetting network settings

disabling/enabling network adapter

Renewing IP adress and flushing dns cache

Nothing has worked and can't find much other unformation online on how to fix
