New PC bought - arrived today. tried to register the mac address with blueyonder but blueyonder say it is already registered. does this sound right? i thought mac addresses were unique? Manufacturer advised me to 'de-optimise' modem - but instructions they gave me don't allow me to. what is de-optimising modem? what is my next move with manufacturer?
