G Router Domain Name Server (DNS) Setup
When you type a Web address into a browser, your router silently sends the website to a Domain Name System (DNS) 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 DNS settings on your router to use a third-party DNS server such as Google Public DNS or OpenDNS.
Why Change Your DNS Server?
Changing the DNS server to Google, Cloudflare, or OpenDNS can help if you are experiencing network connectivity issues due to the DNS server of your Internet service provider being constantly busy or going through problems. This can be achieved by logging into Router Settings, for which you need to know the Username and Password that are required to login to your router.
How to Set Up Google Public DNS on Your Router
Here's a step-by-step guide on how to set up Google Public DNS on your router:

- Log into your router's administrative interface.
- Look for the DNS settings or NGC settings section.
- Change the primary and secondary DNS server addresses to 8.8.8.8 and 8.8.4.4, which are the IP addresses of Google's Public DNS servers.
- Save the changes and restart your router.
