I don't know what the problem is with Netduma, but I am having random disconnects and can't connect to the router (infinite loading) every few days. I never had problems with my main router from Asus! I have plugged in the R3 so many times, but I will definitely sell this thing. I had problems with the old one and am still having problems with the R3. concept idea for gaming 8/10 but from the software/firmware side a 1/10
