Thank you for using the online answer forum. I have a few questions for you. What is the speed that the iPad and iPhone are running over the hotel WIFI? What we see in hotel connection is that the wireless routers are used by a lot of people and the bandwidth is spread out so much that you get little to no speed out of hotel hotspots. You usually don't get this kind of drop off a computer that is hard wired directly into the router of that same hotel. What I would like you to do for us is to download the speedtest.net app on those devices and run them and I will post what the speeds needed to stream from those devices below.
Hope this helps,
