.Thanks for the quick reply Fraser.
That is the way it is setup now as it was totally unusable in Modem mode, i had it setup in Modem mode as i had the R2 setup like this for years without any problems.
I started to reconnect everything back to the R3 last night one at a time.
i had already setup Congestion Control and ping optimizer, but i will try 70% / 70% as you suggest and leave it for a while.
What i dont understand is, R3 is in the DMZ of the Superhub and the only thing in the house connected to the internet is my PC, nothing else wired and nothing connected by Wifi, if the Superhub is controlling the Wifi i get a steady average Latency, as soon as i put the R3 in control of the Wifi ( again nothing connected ) the average Latency doubles.
