I've had the Netduma R1, for quite some time now.
And I've had many issues, to the point I dont know if it's the router, or my line to my house. I get CONSTANT lag spikes,bufferbloat, random packet loss. I play all CALL OF DUTY games, and I'm currently playing black ops 4.
One minute I'm shooting through a guy, the next minute I'm getting hit markers, and the next, I'm getting a super fast kill. Every single day, afternoon, night, I have to mess with the router to get a proper kill. And even THEN, I barely get the kill... so beyond aggravating, and the worst part? I know I am good at these games, constantly went 30 & 0 with the game, before I moved into this house 3years back. And now I fight my internet, more then i fight in the actual match. That's why I bought the router. Yes it has helped! (But not by much)
From a scale of 1 to 10, I went from a 10 crappy internet experience, got this router, and Now I'm a 7, crappy experience. Lol I just do not know what to do. :(
