My house is too big. I think I need to get a smaller one.
My new Powerbook has built-in wireless support and I already had an Airport. The Airport is in the study which is at the back of the house on the first floor. When the Powerbook is in the study then it picks up the Airport connection just fine. When it's in the kitchen (which is below the study) then the connection works fine. But when you move it into the living room at the front of the house then the connection dies.
So I need a smaller house so that the Airport signal covers it all. Or alternatively I guess I could think about moving the Airport closer to the centre of the house.
 That's upstairs for people in countries that don't count floors from zero
