[Wireless Router] How to find the best DNS server?

To ensure a fastest DNS server on your ASUS router could provide a smoother and faster internet browsing experiences.

Here is an easy way to find the best DNS server.

Step1: Connect your PC to ASUS router via Wi-Fi or Ethernet cable.

Step2: Open a web browser and enter your router LAN IP or router URL https://www.asusrouter.com to the WEB GUI.

Note: Please refer to How to enter the router setting page(Web GUI) (ASUSWRT)? to learn more.

Step3: Key in your router's username and password to log in.

Note: If you forgot the username and/or password, please restore the router to the factory default status and setup.

Please refer to [Wireless Router] How to reset the router to factory default setting? for how to restore the router to default status.

Step4: Go to "Network tools" > "Network Analysis"

Step5: In “Network analysis” tab, select “Ping”.

Target: Enter DNS server you would like to diagnose. (For example, google DNS server is 8.8.8.8 or 8.8.4.4, Cloudflare DNS is 1.1.1.1 or 1.0.0.1, or Open DNS is 208.67.222.222 or 208.67.222.220) you can find other DNS via search engine keyword search.

Count: Enter a number in count to run a number of times diagnose, generally, we suggest 4.

Hit the "Diagnose" button and wait for result, for 4 counts will take 4 seconds.

In result, you will see “time(ms)” value as shown below, which means the latency to the target DNS server.

Step6: You can test many DNS servers and to see which have the lowest time(ms). Our example, when diagnose OpenDNS, it shows higher time than Google DNS. Which means Google DNS is faster from our location, therefore we can apply Google DNS as the primary DNS to the router.

Note: DNS server latency is varied by your location and ISP, so there is no one DNS server that will always be best for you.
