Aqara hub and sensors — weak wi-fi in one room
Why does my Aqara hub and sensors weak Wi-Fi in one room?
The short answer
Sensors show as "no response" after a router change, and re-pairing takes an evening. On the WiFiXpert Compatibility Index the Aqara hub and sensors scores 56/100, and its weakest check is "Works on 5 GHz" — which is exactly where this problem comes from. Setup fails if your phone is on the faster band.
We publish what breaks with each router and mesh system, and the setting that fixes it.

Free fixes, in order

- Pair the hub with your phone on 2.4 GHz, standing next to the router.

Before you spend anything
- Only if the hub sits in a spot with genuinely no signal — then move the hub, not your money.
