So, it's two years later, and I grabbed a couple of Blue Cave routers when there was a significant price drop. The hardware has been somewhat unreliable. I had to return two of these Blue Cave devices because the wifi (both bands) would just spontaneously stop working. The signal would completely disappear, even though the firmware thought it was still up. I've been less than pleased with them, to be quite honest. The 86U however, has been my main/central router for over a year, and it's been rock solid, with no issues whatsoever.
