DNS translates human-friendly domain names into IP addresses used by networks. A DNS problem can make websites appear offline even when the connection itself is working.
Quick answer
If an IP address works but a domain name does not, DNS may be involved. Changing DNS should be a troubleshooting step, not the first response to every connection problem.
How to troubleshoot
- Confirm whether the issue affects one device or multiple devices.
- Run a fresh connection test before changing settings.
- Check the router, signal strength and internet status separately.
- Make one change at a time and test again.
Why this matters
Good troubleshooting separates local device problems, Wi-Fi problems, router problems and ISP problems. That prevents unnecessary resets and makes it easier to explain the issue to support.
