Why Speed Tests Change By Room
A speed test measures the connection from your device at that moment. If you move rooms, the Wi-Fi signal path changes, so the result can change too.
Why Results Vary
- Walls, floors, mirrors, tile, and metal reduce signal strength.
- Devices may switch between Wi-Fi bands or access points.
- Neighbouring Wi-Fi networks can add interference.
- Distance from the router affects speed and latency.
How To Read The Pattern
- Fast near router, slow elsewhere: likely Wi-Fi coverage.
- Slow everywhere: check plan, modem, provider, or router.
- Good speed but poor calls: check upload, latency, and jitter.
Best method
Use the same device for all room tests so the comparison reflects room conditions, not device differences.
Turn this into a room-by-room diagnosis
Run the free WiFiCheckup test beside your router and in the problem room. If you want the results saved, the $9.99 report emails you the room health diagram, likely cause, and recommended fix path.
