How to Configure a Router to Work With a DSL Modem

A network router allows you to connect multiple computers to a single incoming DSL connection. The router serves as an arbitrator between the computers on the local network and the Internet, tracking which computer sends each Internet request, and routing the resulting information back to each one. Most routers are shipped with default settings, which will allow them to work properly for home and small business users out of the box with minimal configuration.

Things You'll Need

• Ethernet or wireless router
• Two Ethernet cables

Instructions

1. Disconnect any computers which are connected directly to the DSL modem.

2. Power down the DSL modem. Wait two minutes, and power it up again. The indicator lights should cycle through demonstrating a successful connection negotiated with the Internet service provider.

3. Connect an Ethernet cable from the data-out port on the DSL modem to the incoming data port of the router, and power the router on. The router should also display a cycle of indicator lights indicating a successful connection.

4. Connect an Ethernet cable from a data-out port on the DSL modem to a computer. Open your network control panel or system preference pane and confirm that your computer is set to "Automatically Configure" or "Use DHCP Networking" (depending upon your operating system). Your computer should be assigned a numerical IP address from the router; the router's IP address will be displayed after "Router:" in the control panel.

5. Open a Web browser window and go to the router's address. For example, "http://192.168.1.1." You will be prompted for a username and password; enter the username and password you have previously assigned to the router, or the defaults as indicated in the manual.

6. The configuration page for the manual will appear. Many routers will have a tabbed interface to present many different configuration settings. The settings you are most likely to need will be on the first page, such as turning on wireless access to the router or enabling WPA encryption for wireless access. The default settings will suffice for most home users. Consult your router's manual for details on the other settings, and why you might want to change them.

Tips & Warnings

• If your computer does not negotiate an automatic connection with the router, try resetting the router's firmware. Your manual will have instructions on how to do this. Most routers are reset by inserting a paperclip into a recessed hole on the back of the router and holding it pressed for 2 to 3 seconds.
