I was using my ethernet just fine, all of a sudden my computer crashed and I had to restart it after some random BSOD (I unplugged the WIFI adaptor and that's when it happened) after that, I had to reboot my PC in safe mode (turns out the WIFI adaptor was the culprit as it had some compatibility issues with Windows 10 so I got a new one) after rebooting my computer, my ethernet connection says "Unidentified connection" I have tried everything, updating my drivers, cmd commands, restarting my router and computer countless times, using device manager and uninstalling and reinstalling the network driver but to no avail.

I did, it said that your ethernet doesn't have a valid IP configuration. But even after trying all the netsh commands and changing my IP and DNS as well as resetting my tcp/ip, it doesn't seem to work.
 
1) On your keyboard, press the Windows logo key and X at the same time, then select Network Connections. 2) Right-click your network adapter and select Properties. When box pops up-3) Click the Install… button. -4) Select Protocol and click Add- 5) Select Reliable Multicast Protocol option and click OK to install the protocol. Restart your computer and see if internet come up.
 
Does the ethernet work in safe mode with networking


The IPCONFIG command might give you a clue. Do you get ip addresses or is the port

You could try to boot a USB linux image. These run completely off the USB stick and will not affect your windows install. This mostly is to be sure the hardware is good.
Unfortunately all you will know is the hardware is good but does not tell you what windows has messed up. At some point you consider reinstall rather than to try to find it.
