I've upgraded to the latest early access version and been using it about a week now. Seems about the same. Maybe small improvements. I'm not sure if Im not properly configuring it or whats going on. I also had my isp send someone out to see if I had any issues with my line from the street or something. Everything was fine and I had him hook his meter up to the modem with the duma removed and then again to the router when plugged to the modem. My speed difference was nearly half..
