Does anyone from T-Mobile moderate this and can we get advice? Re: Cannot connect to home internet app. Ok I fixed my issue. I deleted the app, then went into the Wi-Fi settings on my iPhone and 'forgot' the network, rejoined the network, reinstalled the app, then it worked. Hope that helps others.
