If you see the No Internet access message, it can be due to a loose Ethernet connection to your PC or the router. Disconnect the cable from your PC and router’s port. Then, reconnect the cable and watch for the click sound to ensure it’s firmly connected.

Your router has multiple ports. The Internet port is used to connect your router to the modem. Make sure the cable is connected to the Ethernet port and not the Internet port.

Try to connect using a different Ethernet cable. This will help you determine if the issue is with your cable or something else. If you are shopping for a new cable, explore our guide on choosing an Ethernet cable for your wired connection to make the best decision.

Additionally, try to use a different Ethernet port on your router. If it works, you may have a faulty port requiring attention.

4. Perform a Power Reset for Your Modem and Router

You can create a new connection with a quick power reset. Useful to fix issues triggered by a temporary glitch.

Note that your Internet will be temporarily unavailable during the power reset. Make sure to pause any activity that relies on an active Internet connection.

To power reset the modem and router:

  1. Unplug the router’s power brick from the wall outlet.
  2. Next, unplug the modem power brick from the power source.
  3. Leave the network devices idle for a minute or two.
  4. Plug in the power adapter for the router and then for the modem.
  5. The modem and router may take some time to power on fully. Wait for all the lights to stop blinking.
  6. Once done, check your PC to see if the Ethernet connection is restored.
