Пытаюсь построить радиоканал - две точки расстояние 4км антены внешние - вот результат:

Transmit Success Rate 24 %

Receive Success Rate 100 %

RTS Success Count 0

Transmitted Frame Count
Transmitted Frame Count 33

Multicast Received Frame Count 0
Received Frame FCS Error Count 0
Received Frame Duplicate Count 91
Ack Rcv failure Count 250
