Now that we have provided an overview of the scenarios where using an Ethernet Cable for connecting to a router is advisable, we will guide you through the process step by step.

To proceed, you will require two Ethernet cables. You will need one for linking your modem to the router and another for connecting your device (a laptop, PC, TV, etc.) to the router.

Here are the steps:

  • Step 1: Start by unplugging the power cable from the back of your cable or DSL modem if your wireless router is connected to a power outlet.
  • Step 2: Connect one end of the ethernet cable to the Ethernet port on the back of your DSL modem or cable. Like phone cables, make sure that the tab extending from the side of the connector faces in the direction of the cutout on the side of the ethernet port. Push it in until you hear a click.
  • Step 3: Now connect the end of this ethernet cable to the port labeled “Cable/DSL ” “Internet,” or “WAN” on your router’s backside.
  • Step 4: Grab another ethernet cable and connect one end to any remaining ports numbered 1-4 on your router’s backside. Feel free to choose any port; these numbers are just for reference.
  • Step 5: Finally, plug the end of this ethernet cable into an available port on the back of your router.
  • Step 6: Reconnect the power cables for both the DSL modem or cable and wireless router, and you should be up and running with internet access on your computer within 30 seconds.

Troubleshooting Network Issues

Dealing with and troubleshooting network issues can be frustrating, especially when you rely on a Wi-Fi connection. However, it’s always a good idea to have an Ethernet cable handy if you encounter connectivity problems. This cable can be really useful for resolving issues or maintaining a connection while you work on finding a solution.

Moreover, we suggest using an Ethernet connection when conducting our internet speed test. Simply connect your computer directly to the modem using the cable. Then use the connection to assess the performance of your router.
