I have just upgraded my broadband hub and have successfully reset five of my six DS100 plugs to work with it and all is well.

But for one of them I am unable te reset it using the reset button. When plugging it in it goes through  three stages from 1 amber to 2 flashing green then eventually to 3 red. At any of these stages I press the reset button and hold it down but nothing happens until it eventually goes red. 

I have tried on the old hub aswell but still get the same problem.

Any suggestions or should I just give up on it and buy a new one?
