@john_sina Facing the same issue. 2.4ghz maxes out at around 50 mbps. Haven't found a fix yet. did you?

I have a 100 mbps fiber connection on which the C20 is only delivering 50-55 mbps on its 2.4 ghz channel. The Archer C20 claims to support 300 Ghz on its 2.4ghz channel. So why is it only delivering...
