A:Answer You could cancel your cable as long as you keep you wi fi. In order to get all the channels you currently get with cable, you would have to subscribe to a streaming service such as hulu, you tube, etc. Another option is to keep you cable service, but get rid of smaller box in the bedroom. You would then download the Xfinity app to your firestick and then you can get everything you get on the main cable/dvr box. You would save a few dollars for the rental you are paying on the smaller box. There are more options than what i have outlined above. The short answer is that you could get rid of Xfinity and do everything through streaming through your Firestick but you will want to investigate what streaming channels you will actually receive and how much it will cost you for the channels for which there is a monthly fee.
