My neighbour has been on Sky BB package for a while, everything was fine at first then the netgear modem (wireless) started to go wrong contacted sky several times but with no joy, eventually they asked us what they could do and we suggested getting a new modem, when they tried to connect it, it too would not work, from what we have been told the modems sky provide have a specific MAC code in them and only they can connect, tried contacting sky several more time since then (and we are now talking from the middle of April) with still no joy.
