Cannot connect DVR with tablet app
I generally try to do my own searching so have done a fair amount of troubleshooting over the past 3 days and am out of ideas.
Problem: DirecTV app on a Kindle Fire tablet continually fails to register with DVR. Problem is limited to the one tablet: my iPhone and my wife's iPhone and iPad register/download/watch as per normal. Problem is also new: this tablet had been connected properly until a few days ago when the app became unstable so I reinstalled it and then couldn't register it. Under app settings -> Receiver Control my DVR is listed as available (with a little green light) with a correct IP address yet continues to fail to register.
-Reinstalled DTV app on tablet.
-Reset router and confirmed within the router settings that tablet and DVR are on the same Wifi channel.
-Reconfigured network settings on the DVR, including manually changing the IP address. Tablet found the new modified IP under Settings -> Receiver Control yet still wouldn't register.
-Turned off External Device usage from the DVR Whole House settings, then turned it back on.
-After all this mucking around, tried resetting DVR and reinstalling app again and confirmed router was properly connecting with both devices and the problem persists.
I watch 95% of my TV via this tablet and would appreciated a resolution.
