I play on wired, Comcast 150mbps connection. I am a network engineer so I can spot network problems pretty easily. It's not network lag. Network lag would be characterized as losing control of your character and then the the game will look as if it is catching up. I have experienced network lag in this series before during brief lag spikes or outages. In those cases I can clearly identify the problem by going to the network performance graph in the game and see the red > yellow spikes.
In this case I will lose control briefly but the network graphs are all stable. This is more synonymous with input lag. Input lag is where you press a direction or button on your controller and it takes a bit before the game responds. Yes, the player will glide and returns after a bit. As I stated, maybe 5 seconds. I can try capturing an event on my Xbox and link it.
