Android Tablet Samsung S7 - continually pausing during show streaming

I have the EXACT same problem as described with this forum and I have had it for many months now. My tablet continually and excessively pauses while watching programs like CNN, MSNBC, Sports using the xFinity Streaming App - it does not matter what I am watching, they all pause for at times it seems like a few seconds to a minute or two before replaying and where the content it missed is now that, missed. In fact, I purchased a new Samsung S7 tablet several months ago thinking that it was my older Samsung tablet causing the problem and I have the same problem. I have performed all of the remedial tasks as recommended before - I have forced stop, cleared the data, cleared the cache, deinstalled and reinstalled the app, rebooted the tablet.  We did a side by side comparison between my wife's new Apple iPad and my new Samsung Android tablet and my Samsung pauses all the time and hers never pauses while watching the same show/channel on our two tablets at the same time.  We have placed my Samsung tablet right next to the Xfinity router and I still have the same problem of pausing all the time. These problems are effectively making the Stream application useless and I would like a specific fix recommended to what is a really annoying problem.  I have already invested too much time trying to make this apparently buggy application work on a mainstream, newer, Android tablet. Thank you.
