The speeds you’ve mention that you’re getting is pretty darn good.
So far it’s still at least as fast as our Comcast when I lived in Bellevue, Wa. Only downside is that when we get some of those Kentucky rainstorms it goes away. But they usually last less than a half hour. The real concern about those storms is having to grade the hill part of my driveway afterward. :(
So what’s the lowest estimate for overlaying the driveway? lol
