[X4U] Airport express question

[Mark Des Cotes]

Hi all,

I have a follow up to my "wireless printing" question. I bought an  
Airport Express (not the Extreme) but wont be using it until after  
Christmas. In previous posts many of you mentioned how you used the  
AP Express to boost your WiFi signal. How much area does the AP  
Express on it's own cover if you needed another one to boost it's  
signal? I have a 2000 sq ft home. I plan on setting it up in roughly  
the centre on the top floor. Will the signal reach throughout the  
house, including the basement?
