My home is 2 stories and I have my Airport extreme on the first floor connected to my ISP. I am curious if I purchase a second Airport Extreme can I plug it in upstairs and give out a stronger signal without connecting the two extreme's via ethernet? Can it just tap off the wi-fi and share it for more coverage?
 
Yes. It's called WDS mode. Unfortunately, it cuts the speed in half as the remote unit has to rebroadcast the signal to the main one.
