Dear,

I mounted a link with 2x NETMETAL5 (RB922) and 2x rocket rd-5g34 with SLANT system (AF-5G-OMT-S45) as below:

(ENLACE1)

A-POINT RB3011-ether2
<1Gbps cable>
B-POINT RB922-ether1
<702Mbps / 780Mbps nv2> (65KM)
C-POINT RB922-ether1
<cable1Gbps>
D-POINT RB3011-ether2

Signal = TX-45 RX-46 702Mbps / 780Mbps
SNR = 60dB
Distance 65KM


Between A and B it sends 350Mbps TCP in BTEST (cable)
Between B and C it sends 170Mbps TCP in BTEST (wireless)
Between C and D it sends 350Mbps TCP in BTEST (cable)
Between A and D sends only 70Mbps in BTEST (cable + wireless)

THIS IS PROBLEM. POOR Performance between ROUTERs connected in NETMETAL.
Wireless speed is very good.(between netmetal) but in external ethernet bridge is poor performance.

What Ros Version?
Bridge fast forward active?

1. what Modulation Rates you see if you reduce power a little bit to get around -55??

2. nv2 is not optimized for 802.11ac

3. with this distance no chance for 802.11 (higher troughput)

What channel width you have used?
We want to setup several PTP links on triple chain NetMetal, but 5ghz is licensed in our country.
