Unfortunately, to watch a lot of shows on your mobile or tablet, it requires you to have a cable subscription.
I actually watch a lot of my programs separate from cable programming. But, I do have cable programming. You can get a lot of programming separate from cable.
Yeah. I'm assuming you mean getting Internet access via your cable along with TV? The bandwidth is capable of handling streaming video. That's what I have, so no problem using my mobile stuff in my home. But when visiting elsewhere, the wi-fi bandwidth sucks and can't handle streaming video very well (or at all).
