Ethernet not working

[kristofk]

Hi,

 

So I noticed that my wired ethernet connection isn't working and my PC is using wireless connection instead. I tried multiple cables but it doesn't fix the problem. How can I troubleshoot if the connector itself is broken on the motherboard? (The router is fine too.)

If you have an Intel network card. The way I usually check If I have network problems is this: Device Manager > Network Adapters > Link Speed > Diagnostics, I usually run all 3 tests. Also try reinstalling the driver for your network.

Have you tried turning off and on again?

This might sound silly but have you disabled the wireless nic? or at least disconnected from the WiFi? Then tried with a cable?

1. Look at the ethernet port. There should be at least one indicator light next to it, which lights up when there is connectivity. If there is no light then you dont have the indicator led or there is a hardware issue.

 

2. Look in windows network center (bad translation ?), there should be a local area connection there. If there isn't, go in device manager and check if your ethernet adapter is recognized.

If there is a yellow triangle next to it, try to restart your pc. If the triangle stays there, reinstall ethernet drivers.

 

3. Disable wifi to make windows use the ethernet connection. (wifi has priority for some weird reason...)

 

If it is still not working, make sure your cable is okay and the ethernet adapter is enabled in bios. If it is enabled but windows can't find it, then you have a faulty mobo.

You should also try another port on your router.
