I have several sites with GigE-APC-HV's and GigE-POE-APC's that run GigE
with no issues, other than them clamping during thunderstorms and cause
some CRC errors which is perfectly acceptable. 450's, licensed radios.
All kinds of stuff. No 450i APs though. Well, most of the 450s I just
leave at the default Auto 100F/100H/10F/10H since there's no real reason
for gigabit until we get 30MHz channel support. But I have tested it
with Forrest's new GigE PowerInjector+Sync injectors and it does work fine.
The only thing I can think of is to try turning off the sync pulse on
the SyncInjector and see what you get. Per port via software, or just
unplug the SyncPipe if you're on site.

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

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.

15:52:09 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?
