can I use two airport extremes to extend wifi signal?

I bought a new airport extreme to replace my older one - can I place the older one in the garage via ethernet to have wifi in the garage?
thanks

  • Yes...

    :-D

    And if you put in the exact same credentials (so same SSID, Password and authentication method) your device will automatically switch between the two (wifi Roaming). This means your device will be using the network that has the strongest signal.
