I am curious on how to setup two Airport Extreme's together. I have a two story home with the first extreme on the first floor, and the second floor receives a weak signal in certain areas. What I've done so far: From the first airport extreme I plugged an ethernet cord in the back and hardwired it upstairs to my office and plugged it into the back of my other airport extreme but it's making me setup another network and not just sending off the same signal. So the cord and everything else is in place just need tips on actual configuration. Thanks a ton!
