I'm not savvy enough to know what "bufferbloat" is

I know the issue of disconnects has been intermittent for a while now, but I couldn't say exactly when it started happening. I do know I upgraded my speed on June 6th with Frontier, and then got the router and hooked up around that same time (the router says it was delivered that exact day, too). I honestly can't clearly recall which happened first, but I do know I had no issues w/ Frontier before the upgrade from 1Gbit to 2Gbit nor with the Nighthawk RAX70.

And in any case, why is it that after a router restart on the RS700, the issue is (temporarily) fixed for the next day or so?
