I have two Mikrotik wifi access points connected via Cat6 cabling and powered up using passif PoE injectors (cabling length: 20m and 30m)
At both ends I have Cat6 sockets ends (568B) with short Ethernet patch cables
I can't get the devices at either end to negotiate a Gigabit or Fast Ethernet connection (and yes, devices at both ends are Gigabit capable)
At the moment the best I get is 10 Mbps and that doesn't even seem to be stable: packet losses from time to time
I checked my cabling using a GREENLEE TEXTRON-NC-500 Netcat PRO 2 and all seems tip top
The cat6 F/UTP cable sections pass through the ceiling plenum, and are enclosed within convoluted sleeving from one end to the other
I have another set of cables that follow a different path, along the foot of the wall) and have no issues whatsoever (1 Gbps)
The ceiling plenum has A/C ducts, IR Infrared Motion Sensor Switches, and the lighting systems of course.
I can only assume that something is causing interference, but this is the first time I come across such a phenomenon.
Tomorrow I will plug the APs straight into the switch to see how they react; if all is well then it will reaffirm my assumption that interference is the trouble maker here
Can anyone confirm or contradict my assumptions ?
