How to use a wireless cable modem router as a repeater

When you use a wireless cable modem router as a repeater, you set it up as a secondary router so that it extends the wireless signal of your first device located nearest your Internet modem. This is especially helpful in large homes or buildings with thick walls where the Internet signal weakens in certain areas of the structure.

Open the Internet browser on a computer that is located nearest the main wireless router. This is the router that connects to the modem and brings the Internet into the home or office.

Type in the router default IP address. This is usually 192.168.1.1, but some routers may have a different IP address and you will need to check with the instructional manual to find it.

Click the "Wireless Settings" tab and write down the username, password and the wireless network mode being used. This mode could be "B,""G,""N" or "Mixed."

Set up the second wireless router modem in an area where the Internet signal begins to weaken. Connect a network cable to the first network port on the wireless router modem and connect the other end to the network port on a computer. This is only for set-up purposes.

Click the "Basic Setup" tab when the router IP window appears. Select the "Network Address Server Settings" (DHCP) and check the "Disable" box. This will allow the modem router to get these settings from the main router.

Turn on this computer and open an Internet browser. Enter the default IP address for the router, which is 192.168.1.1., unless otherwise noted in the router instructional manual.

Click the "Basic Setup" tab when the router IP window appears. Select the "Network Address Server Settings" (DHCP) and check the "Disable" box. This will allow the modem router to get these settings from the main router.

Locate and click on the "Wireless Settings" tab in the top toolbar and change the username and password to those used on the first router. Do the same for the "Wireless Network Mode." This is the information you wrote down.

Remove the network cable as the repeater is set up. Connect to the wireless connection using the icon in the taskbar next to the time. Open any website you want.

Select the "Wireless Settings" tab on this router. Change user name and password and the "Wireless Network Mode" settings to those you wrote down.
