A modem connects to an access technology or ISP link, while a router moves traffic between networks and usually manages your local devices.
Quick answer
Many home gateways combine modem and router functions in one box, which is why the terms are often mixed together.
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.
