I replaced my VMNG300 yesterday with the superhub (100MB) as I was having problems gaming. I did notice whilst dismantling my old set up that I had the wrong power supply to the VMNG300, it had a 12v 1.5A instead of 12v 1A
Maybe this caused my gaming "stickiness" problems?
Anyway I set the superhub up and it's working perfectly, no lag whatsoever and no drop outs or wireless problems yet
Here's a TB graph. (the first couple of hours packet loss was me messing around with speedtests / downloads etc - all fine
