@bmw199 your post is totally incorrect.
PS Vue is available on most all streaming solutions such as Roku, Fire Stick, etc.
PS Vue works very well; I've tried it on both 25mbps and 100mbps (which I currently have). HD worked flawlessly on both however at 25mbps other devices slowed down.
Internet speed should be as fast as you can afford (no one ever said they have too much speed), and buy a good router such as this guy which I also have:
Asus RT-AC3200
50mbps is more than enough speed for Vue on 2-3 TVs and a couple of devices. Whether it's "good enough" will depend on your router how many other devices are connected/using your network at a given moment in time. Like I said earlier, no one ever said their internet is too fast. At 100mbps with the router I linked (or a comparable one) you'll be able to handle anything.
