Hey, .. Just got an imac From a PC upstairs (2 floors with hardwood) we have three computer's internet connected through wires that run through our house. For some reason the box the wires all meet at also emits wireless internet signals. When I had my old PC here in the basement it could not pick up the signals, but my new imac can. So now I'm wondering if I should connect to the internet through the wires or through wireless, if it makes a difference? Whatever is best for the imac/saving energy/better connection?
