Ethernet not working when I restart my PC?

Silverbackk · July 21, 2020

Hi, I recently built a new high end PC and I'm having an issue when I restart, where I have no Ethernet connection. However when I shut down and turn it back on it works fine? I have also tested the WiFi connection and that seems to work fine after a restart. So it's just Ethernet that's having issues. I'm wondering If its the cable itself causing problems? I would much appreciate any suggestions before routing a new 20m lan cable.

I have tried resetting network settings and un-checking the save power options in device manager for my Ethernet (no luck).

Any advice/help is much appreciated.

open up CMD if you use Windows OS , ( run it as administrator ) type in

netsh winsock reset

ipconfig /flushdns

and try one more time.
it may help you.

Have tried that and it hasn't worked unfortunately. I also reset the network again and tried a new Ethernet cable. still not working?

I managed to find a fix for this issue. After a bit of searching it seems to be a common problem with z490 boards with Intel LAN. I updated the I225-v driver to 1.0.1.7 and it has fixed the problem for me. Hope this helps someone.
