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.
