Windows 10: Ethernet Cable Suddenly Stops Working

Hi needing some help… A couple of weeks ago my Ethernet cable stopped working suddenly. I checked ports and they are fine. I used another cable and it started working again. Now the new cable has stopped working suddenly like the other. Any ideas what I can do to solve/stop this happening? I do have a switcher which is receiving internet fine however when using the cable in the 4 ports on the switcher none of them work with that cable.

Ethernet cable not working.

You need to solve your problem one step at a time, e.g. like so:

• Connect your CAT5 cable directly to your router. If it does not work, replace the cable.
• Connect the cable to your TP-Link wall plug. If it does not work, reconfigure or replace the wall plug.

 

Ethernet connection suddenly stopped working

I'm using windows 10 professional. I have a router given by mu ISP. It has wifi and 4 Ethernet ports. Wifi is working fine (my phone is connected to it), but Ethernet just stopped working, suddenly.
I tried with a different Ethernet cable no luck. I already had newest drivers installed. I reset the network, and after that did a clean install of windows again, no luck. However, when I go to command prompt, I try to ping google.com and it works.
I really really have no idea what could be the problem.. everything was working fine (for years) until today..

 

Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.
