How to Install a Router to Use With a DSL Internet Connection

by Jeff Grundy

Digital Subscriber Line revolutionized the way people connect to the Internet. Before DSL, most Web users suffered with painfully slow dial-up connections that often took several seconds to load even simple graphics in a browser. Modern DSL connections not only enable much faster loading of Web pages, but also allow you users to stream videos and movies, and can support multiple users simultaneously. However, by default, most DSL connections allow only one connection port or interface per telephone line. If you want to share a single DSL connection with two or more computers, you must connect them to a router, which routes and splits the Internet connection between the PCs on demand and as needed.

Shut down your computer and switch off the DSL modem. Disconnect the RJ-45 cable from the computer that leads to the DSL modem if connected. If you have not connected the computer to the DSL modem previously, plug one end of the RJ-45 cables into the "LAN,” “RJ-45” or “Ethernet” port on the rear of the modem.

Plug the other end of the RJ-45 network cable into the “WAN” or "Broadband" port on the back of the router. Connect the AC adapter to the router and plug the other end of the power cable into an electrical socket.

Connect an RJ-45 cable to the computer and then to one of the "LAN" or "Network" ports on the router. Connect other computers to the router with RJ-45 cables as needed.

Power on the DSL modem first, followed by the router and finally the computer. Wait for the computer to boot and log in to Windows with your username and password if prompted to do so.

Launch your Web browser, type the router's control panel IP address into the Address Bar and press the “Enter” key. Depending on which model router you own, the control panel IP address might be "" or something similar. If you do not know the default IP address for your router, check the user guide or manual for the device.

Log in to the router control panel interface with the default username and password. You can find the default username and password in the user guide. On a few models, there may be a sticker on the device that displays the default username and password along with the IP address for the router.

Click the "Basic Setup," "Internet Setup" or other similarly named menu option in the control panel. This page or tab contains the settings you must configure to use the router with your DSL modem. If the modem control panel features a setup wizard or auto installation menu option, click it to have the router detect and configure settings for the DSL connection automatically.

Enter the username and password for your DSL account if required to connect to the Internet. Select the connection type for DSL account if the router did not configure it automatically. For most DSL accounts, you should select "PPPoE" as the connection type.

Click the "Save" or "Save "Settings" link or button in the control panel. Click "Reboot" or "Restart" when prompted to save the configuration settings and restart the router.

Open a Web browser and use the router connection to surf the Internet as you normally would.


  • If you connected your computer to the DSL modem before adding the router, disconnect the cable from the plug into the WAN port on the rear of the router.
  • In most cases, DSL modem users access the Internet with a dynamic IP address. However, if your phone company assigned you a static IP, configure the “Static IP Address” option in the WAN or Basic Settings area of the control panel. Enter the static IP address you received from the phone company along with the WAN Gateway, Primary DNS and Secondary DNS addresses. If you do not have this information on hand, call your phone company and customer service for the details.
  • You should change the default router password after you configure your DSL modem connection. To do this, click the "Advanced" or "Security" menu option in the router control panel, and then click “Access Control” or "Change Password." Type a new password for the router in the “New Password” field, and then again in the “Confirm Password” field. Save the password settings and restart your router. When you attempt to log in to the router control panel again, the router prompts you for the new password.


  • If after entering the default IP address, the router's control panel page fails to load in the browser, there could be an address conflict with the DSL modem itself. Most modern DSL modems use a nonstandard IP address, so conflicts with routers are rare. However, many older DSL modems used IP address commonly used by routers as the default gateway, such as "" or "" If the IP address for your DSL modem conflicts with that of the router, disconnect the RJ-45 cable leading from the modem to the router, then open the control panel interface from the computer. Change the IP address for the router to something other than the default. For instance, if the DSL modem uses "" as its IP address, change the router IP value to "" or something similar. You can usually change the IP address for the router on the "Advanced Settings" tab or page of the control panel interface.
