Can’t speak for frontier but I switched from xfinity and I am going to go back or to frontier. Signal will depend on your location but as for me, I get alright signal although I do notice during certain times things slow down. I mainly use it for phone and tv streaming. Also my biggest annoyance is once a day, maybe because so many people are using it at that time, my internet goes out. Shows good signal but nothing works. If I leave it alone it will come back on it’s own in an hour or so. Otherwise have to turn off and on the router and it comes back.
