How to Configure Wireless Router With DSL Broadband Modem

DSL broadband is one of the most popular broadband connections now a days. This tutorial explains the steps to configure a wireless router with DSL broadband connection. Configuring a router with DSL modem is different from configuring a cable modem with router.  As you know, broadband connection is divided in to two.
  1. Cable broadband

  2. DSL broadband
This tutorial explains universal procedure to setup wireless router with DSL modem and at the end of the tutorial you can see links to product based router configuration guides.
  1. Make sure you can go online with your modem

    Before connecting wireless router to your network, you must ensure that your modem is working properly and you can access Internet though your modem.

  2. Find the IP address of the DSL modem

    Second step is to check the IP address of the DSL modem. You can find the modem IP address from command prompt using the command ipconfig. To learn more about it, visit the link below.

    Here I assume the the modem IP address is 192.168.1.1

  3. Configure Wireless Router

    • Disconnect the Modem from the computer

    • Connect Wireless router to your computer using Ethernet cable

    • Power on router and log in to the Wireless router using its default IP address. You can find the default IP address of the wireless router using the same procedure to find the IP address of the DSL modem. Here I assume the IP address of the wireless router is 192.168.1.1

    • Log in to the router setup page by using the IP address 192.168.1.1. Enter default user name and password when it prompts. Normally it would be admin. If it is not working refer the router user manual.

    • Give Router a different network address IP Address from Modem

      We need to change the third octet of the IP address of the wireless router. On the setup page change the router IP address to 192.168.2.1 and save settings.


      Reason for changing the IP address of the router from 192.168.1.1 to 192.168.2.1 is router and modem IP must be in different sub networks. Third octet of the modem and router IP addresses must be different.

  4. Connect modem to the network

    To connect modem to the network, follow the steps below.

    • Connect modem to the WAN port of the router

    • Connect computers to the LAN ports of the router

    • Power on modem and after 30 seconds power on router.

  5. Power Cycle The network

    It is recommended to perform power cycle after completing the router configuration. To learn more about it, visit the link below.

Note: In some DSL modem the IP address may not be 192.168.1.1 , It may be 192.168.X.1 where

X = any number between 0 to 254 other than 1. In this case we can directly connect modem to the router as the network will work fine.

How to Avoid IP Address Conflict With DSL Modem and Router

While configuring a wireless router with DSL broadband modem, it is very important to select IP addresses for both devices in different subnets. For example if the modem IP address is 192.168.3.1, router can have an IP address of 192.168.X.1 where X can be any number from 0 to 254 except 3. The third octet of the router IP address cannot be the same number as in modem IP address.
