Apple Airport Extreme not only comes with beautiful design but also provides mac users with impressed Wifi performance improvement and security. If you have two Apple Airport Extremes, how to configure to setup and combine them via ethernet for extending your internet in both LAN and WAN connections?

Setup two AirportsWe can easy setup the 2 two Airport Extreme for using together by following AirPort Extreme Setup Guide. In other words, the “wizard” configuration will handle it automatically. However, everyone tends to not be confident to figure it out them-self. Pay your attentions on following steps:

  • Must setup and make the fist Airport Extreme work well. We call the first one is the main Airport Router.
  • Connect your Mac OS X to the first Airport wireless.
  • Reset the second Apple AirPort to Factory Default setting. You don’t have to do that on the brand new one.
  • The Ethernet cable connects from a LAN <—> port on the first (main router) AirPort to the WAN “O” port on the second AirPort.
  • Turn the second Airport on then wait for a few minutes.

The further steps is shown specifically in Mac OS X. Windows users should find the right way based on my steps:

  • In Mac OS X, access the WiFi icon at the top of the screen then look for a listing of New AirPort Base Station (the First AirPort is named TWNDB in the following image). Just below that listing, click directly on AirPort Extreme.
