I have just purchased a 3 x disc Whole Home wi-fi.
I have downloaded the App to my IPhone and receive a message of "Error code 1200 and the message there was no response from your network " My IPhone is connected to the BTWholeHome wi fi ok as it works with other applications / searches.
Could anyone advice me how I resolve this error so that I can use the Whole Home App.

Hopefully one of those links will be able to help.
