TCP is designed for reliable ordered delivery, while UDP uses less overhead and leaves reliability to the application.
Quick answer
Web pages and downloads commonly depend on reliable delivery, while many real-time apps prefer low-latency transport behavior.
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.
