Ok, so I checked all the channels while trasfering a 50gb file. I noticed that on ch40 I only get 45-60% signal, but the trasfer speed fluctuates between 54mbps & 240mbps. On ch161 I get 95% signal, but the trasfer rate doesn't seem to fluctuate at all. So how can I get a stable trasfer at 200mbps or higher?
I'm going to try the 2.4ghz frequency, but with that one I can only get to 130mbps with the bridge right beside the router. I don't know why, but I thought draft n even at 2.4ghz should be able to do 300mbps.
