If you're seeing any lagging or choppy behavior in Luminair's DMX output signal when connected via Wi-Fi, this always indicates that there is either a weak wireless connection or other interference preventing all of the network packets from arriving at the router/access point. Things like walls, support poles, metal stands, human bodies, large amounts of wireless devices, bodies of water and many other objects can all be potential points of interference.
To troubleshoot this issue, try using the devices in a smaller space to see if it improves the signal, or try with another higher-power router or access point.
To prevent the possibilities of dropouts altogether, you can use an optional 3rd-party ethernet accessory
instead of Wi-Fi.
