A:AnswerNo you can not. This device is meant for giving you access to all yoir streaming services. Its not a cable or dvr service. However if you pay for a live tv service such as sling you can access that app from the Fire Stick.
A:AnswerNo you won't; well not for free.. you can modify it to download your favorite shows but that requires some technical knowledge. Out of the box it doesn't do live tv unless you pay for an app to do so.
A:AnswerProbably not unless you 'jail break' it and add an app. It's really best for getting movies and television shows. Kind of like a more current and diverse netlix on crack
A:AnswerThere is a new adapter that Amazon offers that allows the firestick to become wired, just like your computer. This makes for faster speeds all you need is the adapter and a ethernet cord.
