Network goes like:

NanoStation M5 -> Rocket M5 -> Netonix switch (v1.47) -> EdgeRouter -> AF-5X -> AF-5X -> Netonix switch (v1.47) -> EdgeRouter -> Internet

Flow control is off on all ports...

Any good ideas what is causing it ? Customer complains about his gaming....

So, run a ping from each device to it's neighbor, both directions, and see where the spikes are introduced?

Might give you a starting point. That can literally be just about anything, wish I could be more helpful.
