Woke up with ho internet. Switched router on and of and got a slight flicker of blue lights then nothing. Tried again and no lights this time. I've found a similar adapter that has got it working but I'd obviously prefer the correct one.
I found another power supply to use with my superhub that is why I am online. It isn't the original power supply it is just a generic one. My only concern is that it is obviously not the original power supply that came with the superhub.
