Just swapped out the Superhub 2 for an old WNR2000 router I had lying around, Ive updated the firmware and it's working fine but interesting to see there doesnt appear to be any drop in latency or jitter.
So on the face of it no real benefit apart from the router being pretty configurable compared to the Superhub 2. The second big red spike was me swapping out the cables for cat6 ones I had spare.
