Hi

Use Spectrum analyzer to get best (clear) frequency.
please read this article:http://wiki.mikrotik.com/wiki/Manual:Spectrum_analyzer

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:
http://forum.mikrotik.com/viewtopic.php ... 75#p411390

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!

Hi Thanks for the DUal Polarized information.
I was unaware with this and that is why my CCQ float too much. Thanks for the information.
