DECREASE THE POWER!!!
-43 is too high!
30dB dish for 9 Km is excessive.
[My P2P with 28dBm dish, dual polarized, RB433AH + RB52Hn at 23,5Km do 180Mb/s effective with NV2 and 20MHz + 20MHz channel]
For link less than 10Km I use Sextant…
For link less than 5Km I use SXT…
The signal strength must float between -66 to -63 for optimal performance, or you obtain more ROS (return of signal) than 1:1
DO NOT USE WPA or TKIP as CRYPTOGRAPHIC PROFILE, but only WPA2 AES-CCM
Also, I see some error in wireless config, use my example for max throughput:

YOUR DISH ARE DUAL POLARIZED?
IF ARE DUAL POLARIZED HT must transmit and receive on both channel 0 and 1
IF ARE SINGLE POLARIZED HT must transmit and receive only on channel 0 and NOT on 1 [and also the module must be properly internal connected]
Remember to set: country=italy with your country!
