Check Ethernet Cable

Ethernet cables have a secure mechanism, but occasionally they can come loose. Ensure that your Ethernet cable is securely connected to both your computer and the router. Any loose connections could lead to disruptions in the network. For dongle users, confirm the dongle is fully inserted into your computer’s port.

#2: Inspect Cable Health

Inspect Cable Health

If a loose connection isn’t the issue, inspect the cable for bends, rips, or visible damage. A damaged cable may result in a poor or non-existent connection. To rule out the possibility of a faulty cable, consider swapping it with a known-working Ethernet cable and try plugging the cable into different ports on both your computer and the router or switch.

#3: Restart Your Devices (Network & PC)

Sometimes, a simple restart can resolve connectivity problems. Reboot your computer and router to refresh the network settings.

Restart your devices
  • Start by powering off your computer, router, and any network switches. Ensure that all devices are completely turned off by unplugging their power cables.
  • Wait for 1-2 minutes, allowing any residual power to dissipate.
  • Now, power on the router and any network switches. Once these devices are fully operational, proceed to turn on your computer.
  • Finally, check if the Ethernet connection is now functioning. If the issue persists, follow the next troubleshooting step.
