I recently canceled my inbound home cable internet because my unlimited T-Mobile LTE on my iPhone is enough for me (I'm single). I have an AirPort Extreme (with a USB Connected external HD), a MacBook Air, 2 Apple TVs, an iPad mini, and an iPhone 5. The iPhone 5 is the only device that is connected to the Internet. Before I canceled my cable internet I had successfully maintained my iPhone on both the LTE network from t-Mobile (for Internet) and my home AirPort Extreme wifi (for networking to the other devices). i did this by deleting the router information in wifi settings on my iPhone but leaving the other wifi settings info intact (IP address, subnet mask, and DNS). Well now that my cable intenet is gone I'm struggling to get everything to connect to each other. I've tried restarting all devices. I've tired setting up the AirPort Extreme anew. I've tried it in "bridge mode," etc but I can't get video to AirPlay from my iPhone to the AppleTVs. Likewise I can't get video on my MacBook air to AirPlay to the TVs wither. I can get Audio from pandora or iTunes to play but when I try AirPlay YouTube or Netflix I get an error message. Same goes for video from the MacBook air. Over set the AppleTVs to NOT AirPlay from iCloud. I know all about how some apps won't allow video airplay to AppleTVs (showtime for example) - this is NOT what I'm talking about. I'm talking about apps that should be able to video airplay to an AppleTV that will now not work as they used to. Anyone have suggestions? Thanks!!
