Problem with mikrotik AP sector antenna

I have AP sector antenna which I set up on the proper height and optical visibility of tower but there are problems. We have about ten users there which are connected with SXT mikrotilk antenna. But some users respectively some locations doesn t receive proper signal which manifested with drastic fall of internet speed. Some locations have ideal speed, and some locations have an oscillating speed that falls in the evening. The frequency setting is set at the correct intervals.

I dont know what the problem, please can anyone give me solution?

Thanks !

Kind Regards

Check signal levels on both sides and local interference by spectral analysis on the clients side.

Forum Guru, can I input some command in CLI in order to scan necessary frequency at the client side. Because when i input the coomand "interface wireless spectral-scan " card reach 2383 - 2516 bandwidth and it is not enough to cover all frequency.

Thanks !

Kind Regards
