A:AnswerYes. We ditched cable 2 years ago and use Netflix, Hulu, Sling, Amazon Prime and HBO Now with this modem. We have TVs that use wifi and others that are hardwired with ethernet cable, all work fine. Keep in mind your experience will also depend on your internet service and distance from the modem if using wifi.
A:AnswerNot sure. Some cable companies like infinity offer fast service with large volume use to business customers. It may be a note from cable company letting you know the unit is faster than the available band with can deliver for a business. Just a guess mind you.
A:AnswerYes it will and you do not have to use the internet service providers phone service. I have xfinity and ran a package deal and included there phone service but it was not necessary.
