What DNS does
- DNS translates domain names into the IP addresses your device needs to connect to a site.
- A slow or unreliable DNS resolver can make browsing feel broken even when the connection itself is fast.
A real troubleshooting pattern
- After a Verizon router change, certain websites became noticeably slow. An Orbi system was tested and removed. Changing DNS to Cloudflare improved the problem, indicating the issue was more related to name resolution than a need for more Wi-Fi hardware.
A useful test order
- Check whether the problem affects all devices or one device.
- Compare speed tests with actual website behavior.
- Try a known public DNS resolver on one device before changing the whole network.
- Flush local DNS cache if appropriate.
- Check IPv4/IPv6 behavior and router DNS settings.
- Only replace routers or mesh hardware when the evidence points to coverage, radio or hardware problems.
Bottom line
Do not assume every slow website is a Wi-Fi problem. A controlled DNS test can save time and unnecessary hardware replacement.
