I will test with anyone that wants to loan me gear. I really don't want to
keep buying every possible combination.
The dedicated ethernet test equipment never shows a problem. Actually, so
far, I have not found a problem that was unrelated to the occasional failure
during manufacturing inspection.

Ouch. I sell probably 1000 of these a month. I have heard a similar
story
a couple of times. Did my own lab replication and did not find anything
wrong. It always has to do with Cambium. No idea yet what may be
happening.
We have a lot of these deployed. Really only needing 1000base on our
PTP450i units when we use wider channels.
Have you tested with a Mikrotik CRS? I fail to get 1000base from
Mikrotik CRS to CRS with them as well.
I am currently testing an ePMP powered off a Netonix switch with 65’ of
cable to the GigE-APC surge suppressor and then 165’ to the AP.
Rock solid at Gige. Everything looks good.
Have you tried to cut and isolate. Say with a Cambium power supply and a
laptop.
Start at the AP and work your way back adding components until you find
what is causing it to break?
I know that now and then the pins in the RJ45s in the surge suppressors
and other components can get a bit contaminated and some alcohol and a q
tip
will fix the problem.
Went back today.
I have Mikrotik CRS > 52 volts > PacketFlux Gige SyncInjector > GigEAPC
HV Rev A.1 > 100 foot STP > PMP450i. Will not do 1000base.
Removed the GigEAPC HV and replaced with a Monoprice RJ-45 coupler.
Linked and stayed up at 1gbps. Put the GigeAPC back in. Mikrotik
logs show.
15:51:53 interface,info ether9-slave-local link down
15:51:55 interface,info ether9-slave-local link up (speed 1G, full duplex)
15:51:56 interface,info ether9-slave-local link down
15:51:58 interface,info ether9-slave-local link up (speed 1G, full duplex)
15:51:59 interface,info ether9-slave-local link down
15:52:01 interface,info ether9-slave-local link up (speed 1G, full duplex)
15:52:02 interface,info ether9-slave-local link down
15:52:04 interface,info ether9-slave-local link up (speed 1G, full duplex)
15:52:05 interface,info ether9-slave-local link down
15:52:07 interface,info ether9-slave-local link up (speed 1G, full duplex)
15:52:08 interface,info ether9-slave-local link down
15:52:09 interface,info ether9-slave-local link up (speed 100M, full
duplex)
In the end it gives up and goes back too 100M.
Also, have Mikrotik CRS125-24G-1S -> thirty foot of unshielded cat-5e
-> GigEAPC-HV -> Mikrotik CRS125-24G-1S
It will only link at 100M also but if I remove the GigEAPC and replace
with monoprice RJ45 coupler it links and stays at 1Gbps. Both routers
on latest firmware and stable/current ROS.
Have tried different GigEAPC units, new ends and have checked that
everything is grounded correctly to electrical ground.
Ideas?

Was anything ever found out with this? I have Mikrotik CRS > 52 volts >
PacketFlux Gige SyncInjector > GigEAPC HV Rev A.1 > 100 foot STP >
PMP450i.
Will not do 1000base. Both the 450i and CRS have gigabit enabled in
settings.

No Joy. Everything checks out 100%.
I bought one the cambium units for comparison. Its impulse breakdown
voltage is about 5 volts to ground lower than my unit for single pin to
ground. Transverse impulses are clamped much lower on the cambium unit
but
normally that is not an issue.
Pin to pin and pin to ground I have less capacitive loading than the
cambium unit.
They have some other circuitry that I have yet to puzzle out.
Something that is not related to surge suppression.
In any event, your unit, a brand new unit from my stock and the cambium
unit all show 1Gbps on the traffic tester and all show good wiring
continuity and all show good breakdown voltage pin to ground. Visual
inspections are not revealing any solder bridges or manufacturing
issues....
A puzzle for certain. But I am not finished. Stay tuned...

We’re not able to get our Cambium 450i radio’s Ethernet Interface to run
at Gigabit speed.
Our setup is as follows:
Gigabit switch (Tried several brands) à14’ Cat6 Patch àGigabit Sync
injector (48V) à 35’ Best-tronics Cat5 Shielded à 800-800-GIGE-APC-HV à
80’
Best-tronics Cat5 Shielded à Cambium 450i
It works without the 800-800-GIGE-APC-HV. (Cat5 Coupler).
Anyone ……….
