I have Spectrum (former TWC) cable and internet ("extreme" 30 MBPS.) I have a Netgear Nighthawk modem/router. When I check my internet speed, it regularly comes back at 37 MBPS, more than what I'm supposed to get. I can watch Amazon Prime or Netflix on my desktop or via my iPad/Apple TV with no problem. in the month or so, however, my Samsung smart TV regularly freezes up or says I have no connectivity. Houses are steadily being built on my street. Is my share of the internet pipe shrinking? Is it the TV? If yes, what smart TVs are better than others? Any suggestions will be much appreciated.
