This wikiHow teaches you how to use an old router as a network switch. This is useful if you want to connect multiple devices to a wired internet connection. You will have to reset the router to factory settings and change some settings of the router.

Steps

Use a Router As a Switch Step 1

Step 1. Plug the router into a free power outlet

Plug the router you want to turn into a switch (we'll call this the 'switch router' from now on) into a free power outlet. You should see the power light illuminate.

Step 2. Press and hold the reset button on the switch router for 30 seconds

Look for a small button labeled 'Reset' and hold it for 30 seconds until all the lights start flashing for a few seconds. You should see the power indicator light up after a second or so. This will reset the router to factory settings.

Depending on the brand of your old router, you can use a pen or a bent paperclip to press the Reset button

Step 3. Connect a crossover cable from the LAN/Ethernet port to your active internet router to the LAN/Ethernet port of the switch router

The switch router does not use the 'WAN' or 'Internet' ports, so nothing should be accidentally connected to it

Step 4. Connect your computer to the switch router using an Ethernet cable

Connect the computer to an open Ethernet port on the switch router and make sure that your computer is not receiving WiFi signals from the first router. It's a good idea to turn off Wi-Fi on the computer for testing purposes.

If you are using a DSL or satellite internet connection, you may need to use the configuration CD that came with the router to set it up with proper authentication

To find the default login information, refer to the user manual or search online for your router's model number

Step 7. Change the switch router's IP address

This prevents the router's IP address from conflicting with the first router. For example, if the first router has a default IP address of 192.168.1.1, then you can change the second router's IP address to something like 192.168.1.2, as long as it's not assigned to another device.

You can usually find the option to change the IP address under 'Home', 'Setup' or 'LAN'. Please refer to the user manual to change the IP address of your specific router
