Hello;
I have a p2p link, based on rb912 (wireless built-in), good antennas, pigtails, fw 6.6.
On nv2 (N only), I have stable connection, with CCQ 67/67%. Transfers HD up to 120-130MBps @ tcp protocol. Ping at 2-15, avg 5ms - this is quite good and stable link.
Today I have wasted my day because of increasing CCQ, to better results - I have tried to set antennas up to better levels. There was no change.
For a moment, I have disabled nv2 - there was N-only mode.
This mode gives 300/300 connection with CCQ near 100% - excellent, with ping avg. 1ms. Very nice!
Unfortunately, transfer goes totally down. To the HD 10-20MBps level.
I have no idea; why does it working so bad - wireless parameters are taken from lab…
Anybody have an idea?

Hello,
What are the signal levels on both chains and SNR? It looks like interference problem.
You MUST have signal level of at least -55dBm (for stable 300/300mbps modulations) and
clear channels on both sides within 20+(20+20)+20MHz for good ccq (95-100%).
You could try to find better channel and to limit modulations between MCS12 and MCS15 on AP-bridge side.

SNR up to 34-36dBm (if power is fully open), of course I decreased to -50/-55 both chains.
I have tried all freq’s - same ccq/ mcs level.
Hard to understand is fact, that at N (non nv2) mode ccq is about 100%.
Enabling nv2 - back to 65-67% level (both sides).
It looks like software problem, if clear N is with 300/300 and 100% ccq.
I do not understard clear N; with 300/300 - ccq 100%, and transfers on 12-15MBps level.
I have to check on high modulations; but I’m worrying about bad weather conditions.
