If your internet bandwidth is enough, turn on QOS will slow it down. From my experience, QOS always "reserve" some bandwidth for nothing.Hi. I'm new to this, I'll win something using voxel firmware and another question, and I realized that online games work better for me without QOS, why? . StreamBoost? or a hidden netgear setup?
-Netgear R7800
I got a gigabit internet connection(~950 Mbps Up/Down Link). My pc connected to it by wire which got 910 Mbps up/down with QOS and 940 Mbps up/down without QOS, so turn off QOS "release" about 30 Mbps bandwidth.
Also, turn on QOS use more cpu of your router, hence why you feel better without QOS.
