I have set up the first disc and it’s linked to the router. The WH network has been renamed to the SSID of the original Home Hub 5 router, the HH5 has been renamed and Wi-fi disabled. The Whole Home disc is working fine.
The other 2 discs are set up using Wi-Fi. Each is showing a solid blue light but I can’t see them in the app, the only disc showing is the first. And I don’t think they are transmitting a signal, despite the solid blue light.
