If your speed is below the median
- Test over Ethernet, not Wi-Fi. Plug directly into the router.
- Pause other devices during the test — streaming, updates, cloud sync.
- Repeat the test at different times of day (peak: 7–11 PM).
- Document multiple measurements — and contact your ISP if the gap is consistent.
