Knocked the power down to 15/14 dBm (14 dBm on the slave, 15 dBm on the
master). They no longer maintain 8X modulation, and the download
throughput is down from ~~56 Mbps to ~~44 Mbps. So we are losing link
quality, and the NewSess messages are still occurring at about the same
frequency. The Rcv signal is down to ~~ -61/-62 at both ends
(combined). So I don't think this is a "too hot" issue.
Cambium is still working on the CNUT capture files. They have asked for
SAs from both ends, and suggested that we downgrade to 13.1.4 (as stated
before, we are on 13.2, build 34).

I've cranked the output power on the slave from 22 down to 18. It's
started to drop the SNR from ~~ 34 down to ~~32 at this point, and I'm
not sure I want to go too much lower, as I think I will start to lose
8X modulation. Still getting -62V/-62H at the master, which translates
to -59 combined on the uplink.

Sorry, my eyes missed that the post was about a PTP450 not PMP450.
Still, I would be interested to see if it still happens if you
temporarily crank down the xmt power a bit.

This is 5.8 GHz. We set the timing on the AP to match the
co-located PMP450 APs that are operating nearby (both physically and
on nearby channels).
There is no setting on the BHM to auto-adjust power.
This is what the Link Status looks like right now. Maybe the uplink
is a little hotter....

Sure sounds like a problem to me.
Out of curiosity, what do you have the target signal level from SMs
set to on the AP? And as an experiment, if you drop the AP xmt
power something like 3-6 dB, does it have any effect on the
symptom? Cambium says –59 isn’t too hot, but I wonder.
Also, what frequency band?

We're getting these "New Session" messages quite often on a new
PTP450 installation.
Everything else looks real peachy. SNR varying between 32 and 35,
Rcv power ~~ -59; almost equal V/H ratio, etc.
Any idea what it's trying to tell me? Is this a problem? Session
timer keeps getting rest on "some" (not all) of these events.
We're running the 13.2 build 34 on link.
