I have a PTP with two netmetals, a 34dbi ubiquiti parabolic and a mant30. 18Kms with free LOS. I thought that I would get 80Mbps on both way.
I set nstream. Configuration:
set [ find default-name=wlan1 ] amsdu-limit=2048 antenna-gain=20 band=5ghz-onlyac basic-rates-a/g="" channel-width=20/40mhz-Ce default-forwarding=no disabled=no \

CCQ RX doesn't down but RX rate down from 270Mbs/40Mhz-2S to 65Mbps-20Mhz-1S (ht-basic-mcs) as you can see at attached images. SNR=61db, CCQ: 85/85% Signal strength: 51/51
ONLY one rate down the other no.
Is it normal with those levels to get that result?
interferences? I tried 20 and 40 Mhz channel-width and several frequencies.
Someone know what must I do to prevent that ?
I read viewtopic.php?f=7&t=33497&start=100 , I don't have doppler ball.
Maybe the distance is way too long for the devices selected?
Thank you in advance
