Setting up a Belkin Ethernet router as a range extender effectively doubles the size of your wireless network. However, you cannot have two routers connected to one network without disabling the DHCP server on the one you want to use as the range extender. Turning off the DHCP server prevents the router from assigning IP addresses to the equipment connected to the network. This process is then left up to the original router in the network.
Connect the Belkin router to a computer via an Ethernet cable. Plug one end of the cable into the LAN port located on the back of the Belkin router and place the other end of the Ethernet cable into the Ethernet port located on the computer. On desktops, the Ethernet port is on the back. On laptops, the Ethernet port is located on the side.
Place a pin into the reset hole located on the back of the router to complete a master reset. This clears out any filtering or bridging that could negative effect the router. It also allows you to use the default login information to access the router settings.
Open a web browser and enter the default router IP address into the address field. The default address is 18.104.22.168.
Click on "login" at the top of the page. Enter "admin" into the username and leave the password blank. Press "Enter" on the keyboard to load the router settings.
Locate the SSID filed on the "Basic Setup" page. Give the router the same name as your main router. So if the SSID for your main router is Belkin_Home_Router, the SSID for the router you want as a range extender should be Belkin_Home_Router.
Locate the DHCP server settings on the "Basic Setup" page. Disable by clicking the "Disable" radio button. Click on "Save Settings" to save the router settings.
Remove the Ethernet cable from the router and the computer. Connect the Ethernet cable to a LAN port located on the back of the main router. Plug the other end of the Ethernet cable into the WAN port located on the router being used as a range extender. The network is complete.
