When you type a Web address into a browser, your router silently sends the website to a Domain Name System server. The DNS server looks up the IP address and sends it back. Since a lookup must be performed every time you access a Web page, the speed of DNS lookups affect the speed of your Internet access. Instead of using the DNS servers from your Internet Service Provider, you can set up the Google Public DNS service on your router to potentially improve browsing speed.

Launch a browser and type the router's local IP address to access the configuration pages. For example, type "" and press "Enter." Sign in to the router with an administrative username and password.

Select the menu option that enables you to change the router's network settings. For example, choose "Network" or "WAN" from the Setup menu.

Locate the WAN configuration options, which should enable you to specify an IP address, subnet mask, gateway address and one or more DNS addresses. Replace the first DNS server address with "" Replace the second DNS server address with "" If there is a third DNS server address option and it contains a value, either erase the contents of the field or replace it with ""

Save your changes and reboot the router. Launch a browser from a computer that connects to the Internet through the router and verify that you can successfully browse the Internet.
