I’m trying to find an answer to a problem with Surface Pro 2 - 256 that cannot always play the video portion of Apps. They play fine on some wireless locations but don’t play at all on others. They played normally using the wireless system at the Microsoft store and at AT&T wireless setup at a friend’s house but at other locations such as Comcast systems, Starbucks, other hot spots and at my home the video portions will not play. Microsoft has exchanged the computer for a brand new one and their support has spent many hours on the phone trying to understand the problem but so far they haven’t been able to solve it. Not being able to run the video portion of Apps is not a deal buster and the computer operates without problems in other areas it just seems that everything should work as advertised. I’ve tried to understand the different video protocols in wireless transmissions but it’s a bit over my head and I’m not sure if video protocol even plays a part in wireless App transmission or if it’s related to a GSM or CDMA issue. I haven’t seen anyone else mention this problem, unless it’s just assumed there’s a problem with the Apps themselves. I also wonder if it could be some type of problem related to the protocol used in different brands of wireless routers. I tried using the Surface Docking Station with a direct Ethernet cable connection but that didn’t solve the problem. Is there someone who understands all these complex protocols and can simplify it a bit so I might be able to narrow down the problem area?
