Here are the basic steps to configure the new 802.11n AirPort Express Base Station (AXn) to extend the wireless range of the 802.11b/g AirPort Extreme Base Station (AEBS). This configuration is known as a Wireless Distribution System (WDS):
o Power-down the modem; Power-off (unplug) both the AEBS & AXn and power-off the computers.
o Perform a "hard" reset on the AEBS and a "factory default" reset on the AXn. We want to make sure that they are in their "out-of-the-box" configurations.
o For both AirPorts, jot down the AirPort IDs for each of the base stations to be used in the WDS. The AirPort ID and is printed on the label on the bottom/side of the base station. Make sure you get the AirPort ID and not the Ethernet ID.
o Temporarily place the AXn nearby the AEBS. We want it at this location during the WDS setup phase. Once the setup is complete, you can place the AXn at the desired location.
o I will assume that the iMac is currently connected directly to the AEBS by Ethernet.
o We will use the iMac to configure the AirPorts using the AirPort Utility.
o Power-on the modem; wait at least 10-15 minutes.
o Plug-in the AEBS; wait at least 5-10 minutes.
o Plug-in the AXn; wait at least 5 minutes.
o Power-on the iMac.
Note: In this WDS configuration, the AEBS will be performing as the main base station and the AXn will be performing as the remote base station.
Main Base Station Setup - AEBS
o On the iMac open AirPort Utility located in the \Applications\Utilities folder.
o Select the AEBS, and then, choose Manual Setup from the Base Station menu.
o Click Wireless in the toolbar, and then, choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
o Click WDS and then, choose “WDS main” from the WDS Mode pop-up menu.
o Select the “Allow wireless clients” checkbox.
o Click the Add "+" button and enter the AirPort ID of the AXn that you wrote down earlier.
o Click Update to send the new settings to the base stations in the WDS.
Remote Base Station Setup - AXn
o On the iMac click the AirPort status menu in the menu bar and choose the wireless network created by the AXn. Since we performed a reset earlier, the default Network Name will be something like Apple Network XXXXXX, where the Xs are the last six digits of AXn's AirPort ID.
o If not still running, open AirPort Utility.
o This time select the AXn, and then, choose Manual Setup from the Base Station menu.
o Click AirPort in the toolbar and click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and then, choose the same channel as the main base station from the Channel pop-up menu.
o Click WDS and choose “WDS remote” from the pop-up menu.
o Enter the AirPort ID of the AEBS in the WDS Main field.
o Click Update to transfer the settings to the base station.
