Mine suffered from the same. Two things fixed it: 1) Flipping the unit on its side so that the power button is facing me and the wires stick up in the air. Apparently the original run units had a metal base which affected signal from the antenna. 2) Switching the Bluetooth controllers to get the priority no matter if there's a game downloading or not. This feature/option was included in a recent update and you can find it in the Controllers->Settings menu. I have a chocolate brown Kickstarter-backer model and I no longer get controller lag.
