If you get 400mbps real throughput than where is the problem?Dont expect to get 600+, thats just link speeds you will never reach that.
Problem is one way is 400mbps oposite way 300mbps. Why oposite way is slow 100mbps.
I know now 400mbps is max.
Don’t relay on internal btest.
Internal test and real test tell same. I tried copy data over link and speed is 400 and 300mbps. Depend on way.
Maybe you have some network in close proximity to that other side on same/near frequencies?
Try running frequencies usage scan on both sides and set it to lowest used channel.
Scan tell me frequency 5765 is no used. I try put this frequency problem is same. Speed is no better.
How I can know what is best frequency for me? I tried randomly few frequencies but speed is same or bad.
And what Frequencys are used?
This tell me Frequency usage and wireless snooper.
