so i have 4 cubes, everything runs fine until after about an hour one of the cubes just randomly stops mining, but once i cycle the power it starts again and is good for about another hour, all 4 cubes have identical settings and they all have plenty of power. any ideas?
It could be EMF interference. Build a tinfoil cage or metal mesh like screening, ( see faraday cage) around the cube(s) leaving plenty of space for airflow and wrap a couple turns of your lan cable around ferrite core.
Also, its been reported that android phones using your local WiFi network can cause cubes to lock. A couple of of my Cubes had the same problem. Sometime they would run for days, or a few hours when they would just stop and the red status light would stop blinking. Found out that a local Amatur radio operator transmissions would cause these two to lock up when he was transmitting.
Cheers!
