Signal actually rises from -50 to -39 (when measuring signal strength, more is more and -39 is less negative than -50, hence better signal). Is the Rx rate observed while link is utilized or (almost) idle? If while it's idle, then the number is meaningless...

thanks for replying i know -39 is better tahn -50 by negative sign but my signal is -50/-51 for example when it became -39/-51 rx rate drops to 86 my bandwidth is 100 mb when it drops it will only be 40 to 50 mb

Actually I think that signal strength higher than around -45 is too strong and causes distortions in the receiver (driving pre-amp into non-linear range) causing drop in signal-to-noise ratio and hence reduced throughput. Try to maintain signal strength above -45 or -50 dBm.

this is my signal i think it is good but what happens with me is that sometimes signal changes for -39 and it will make problems and after a few minutes it will raise alone
