Problem with ccq

Thu Dec 14, 2017 11:41 am

Hello ,
I have install 2 units on a roof In the distance of ~250m.
I have looked in Unit 1 (which is AP)
The seting are the same in both units: NV2 4502 20Mhz ht=0,1;
I can see the signal is good : -62dBm
also I can see th ccq is 67/10%
so when I do speed test from Unit1 to Unit2
* upload: 70-80Mbps
* downlaod: 6-8 Mbps
I have connected a VWSR Power Meter between the antennat and the cables and I get a resulat of 1.29 (which is great as you know )
so I can conclude there is no problem in the cables. the cables are ~1 meter long.
I have try to replace cables , change radio card , change AP to station , cahnge the antennas - in all I get the same resultats (more or less)..
So where is the problem ?
how can I check it ?

Thanks ,

signal -62 for 250m is low
check the SNR may be low
