Thanks Tosk. I notice on the Mac in internet connect, there is a status bar indicating strength of signal. When I move to the far end of the house signal fluctuates but not below 50%; on the first floor something similar. I don't suppose using the adapter that came bundled with it will make great difference. I could put the router in the hall at the main phone point and use the adapter on the pc and use the airport on the mac. Have to experiment this weekend when I get a chance. Still, very happy with it and at least it gives up net coverage all over the house. Gonna try some BF 2142 now to see how gaming handles. More later
