Problem: Your computer says "Network Cable Unplugged" but you have checked that the ethernet cable is connected properly from your computer to your router or gateway. The ethernet light for your connection is off. And you only have one computer and one ethernet cable.
The scenario above indicates either a computer-related issue, a modem trouble or a broken ethernet cable. Now, how will you determine the actual root cause of your connectivity problem?
Simple: perform a loop test.
Here's what you need to do:
- Disconnect the ethernet cable from your computer.
- Plug the end of that cord to another ethernet port at the back of the router/gateway. Let's say you plug one end to Ethernet Port 1 and the other end to Ethernet Port 2.
- Check for the light indicators for Ethernet Port 1 and 2. If they're on, then the problem is with the computer.
- If the light indicators for Ethernet Port 1 and 2 didn't lit up, try the other Ethernet ports at the back. You can try 1&3 or 3&4 and other possible combinations. If the lights still didn't turn on, probable root cause is a broken ethernet cable. If some of the combinations lit up, then, you're facing an Ethernet failure on some of the ports of your gateway/router.
