Hi All So I have one of the Apple Airport Extreme base station units -- the older oval shaped ones, I think G -- not the newer square style. The range of the unit was fine when I lived in a one story apartment, but we have since moved into a newer place with two floors. The Airport base station is upstairs in the computer room. I find when using a laptop downstairs, the wireless signal is weak to intermittent to none. I suspect this is a range issue. How can I extend my range? I know there is a port on the back of the Airport to add an antennae, but I haven't been able to locate this product. Are there other ways to extend the range? Would I be better upgrading to the newer Airport base station -- does it send out a stronger signal? Would up upgrade to the basestation + range extender be best? Basically, how can I improve the home network? Thanks for any advice.
