I had this same issue my router ultimately it was at the end of its life just stopped working correctly not responding haveing to constant reboot could not update my r2 was 5 years old lol mt experience with duma the software is not were it should be it's just to over priced for the software to have so many issues that also effects the quality of your connection severely and the hardware is mid grade which also effects your connection quality if your running 1gps or higher i would not recommend useing duma over my 5 years with duma it was nothing but a hassle I had to reboot once a week because the router just stopped working and some functions in the software do not work as they should your better off buying a tplink be3600 for 99 bucks that will blow the r3 out of the water I it was a fun experience with duma but I will never buy another duma again you can get better software and hardware for less money 💰
