had some issues with sky when i hooked my pc up to the internet for the first time when it was new

can't rememebr what i did but buggering about with the buttons sorted something out, but i think it was a case of the internet thing not being connected as it wasn't recognising there was an actual connection

the network and settings bit shows my computer connected to the box which is then connected to the internet

in my case the computer wasn't connected to the box so it was a case of simply clicking stuff to make it all work

the other thing you may not have tried is resetting the hub?
