Issues that occur only at night - when the LED's come on generally point to a power problem.

Has the ethernet cables built correctly and tested. Did you use solid copper, AWG 23 or 24 ethernet wire. , no CCA (Copper Clad Aluminum).

Are the connectors wired to spec ? Does the ethernet cable run near power wires ?
