How to Change DNS Settings on Your Router

by Tommy N. Updated Apr 12, 2026

Changing your router's DNS server can improve browsing speed, enhance security, and bypass ISP restrictions. Popular alternatives include Google DNS (8.8.8.8), Cloudflare (1.1.1.1), and OpenDNS (208.67.222.222).

Step-by-Step Guide

  1. Login to your router — go to 192.168.1.1 or your router's gateway IP.
  2. Find DNS settings — look under "Internet", "WAN", or "Network" settings.
  3. Enter new DNS servers — replace the existing values with your preferred DNS. Primary: 8.8.8.8, Secondary: 8.8.4.4 (for Google DNS).
  4. Save and reboot — click Apply and restart your router for changes to take effect.

Tips & Best Practices

  • Google DNS: 8.8.8.8 / 8.8.4.4 — fast and reliable
  • Cloudflare DNS: 1.1.1.1 / 1.0.0.1 — privacy-focused, very fast
  • OpenDNS: 208.67.222.222 / 208.67.220.220 — includes content filtering options

  • Use 5GHz for speed near the router, 2.4GHz for range
  • Change the default WiFi name to something unique and non-personal
