Question Ethernet doesn't have valid IP config

[ChiefKrieg]

My friend's sister turned their internet off without his knowledge/approval. He got it back on and working but his PC's Ethernet doesn't work anymore. We have tried the basic fixes you see along google such as reinstalling the driver, clearing out caches, and changing the ipv4 IP manually. Also have powered on/off PC and Modem.

what do you mean turn it off?
is the internet working on any other device?

Yes internet itself is working in regards to Wi-Fi but the ethernet to his PC isn't giving a connection. By turning it off I just mean powering it down and back up again.
