I have Lite5 device on my roof and FTP cable ~40 meters far. When I plug-in power, I'm able to connect to Lite5 only with 10mbit/s speed. I cut ~5 meters and trying again. No luck. In 100 mbit/s mode, my connection breaks every sec (connect-disconnect..).
So..35 meters and no 100mbits over PoE with standard adapter?:O
