DIAGNOSIS
The machine's Wi-Fi module is not entering setup mode correctly. This is a handshake failure between the device and your phone.
FIX
1. On the machine, press and hold the 'Wi-Fi' button (next to the power button) for 5 seconds until the light changes from blinking to solid.
2. On your phone, forget any existing 'Dyson' Wi-Fi networks in your settings.
3. Close the Dyson Link app completely and restart it.
4. Follow the in-app setup, ensuring your phone's Bluetooth is on and you are on your home's 2.4GHz Wi-Fi network.
IF THAT DIDN'T WORK
Perform a network reset on the machine. With the device powered ON, press and hold the 'Airflow' and 'Oscillation' buttons together for 10 seconds. The Wi-Fi light will flash rapidly, indicating a reset.
HEADS UP
The HP07 cannot connect to 5GHz Wi-Fi bands or networks that use a 'captive portal' (like many dormitories or hotels). It requires a standard 2.4GHz home network.
