How to get the most accurate FAST WEB result
- Use Ethernet — Wi-Fi cuts speed by 20–60% depending on distance and interference.
- Close background apps — streaming, cloud sync and updates consume bandwidth during the test.
- Test at different times — evenings are peak hours; compare morning vs. evening to detect congestion.
- Reboot your router — monthly restarts keep firmware fresh and clear connection tables.
