I have an Airport Extreme (AE1) as my wireless router with two other Airport Extremes (AE2 and AE3) connected to it via ethernet and operating in bridge mode. Together they cover the first floor of my house with wifi but I want to use an Airport Express (AX1) situated on the second floor to connect wirelessly to AE2 and extend my wifi network to the second floor of my house. Nothing I have tried has allowed AX1 to extend my wireless network. I'm using the latest Airport utility in Mavericks and AX1 is the old plug-in type but it's the newer "n" version that is still configurable by Airport Utility. Any suggestions would be appreciated.
Step 1 : Power on all 802.11n Wi-Fi base stations and allow them time to appear in the AirPort Menu Extra.
Step 2 : Open AirPort Utility (On a Mac choose Go > Applications from your desktop click the Utilities folder then open AirPort Utility. In Microsoft Windows choose Start > All Programs > AirPort to start AirPort Utility).
Step 3 : Select the primary Wi-Fi base station in the Base Station Chooser then click Continue. Note: If you see a message appear that indicates that the Wi-Fi base station has been reset click Cancel to continue.
Step 4 : Click Manual Setup. Enter the base station password if necessary.
Step 5 : Click AirPort in the toolbar.
Step 6 : Click Wireless.
Step 7 : Choose "Create a wireless network" from the Wireless Mode menu.
Step 8 : Select the "Allow this network to be extended" checkbox.
Step 9 : Enter a Wireless Network Name.
Step 10 : Optional: By default Wireless Security is set to None so that no password will be required to join the network. We recommend you click on the Wireless Security menu select WPA2 Personal and create a password between 8 and 63 characters long.
Step 11 : From the Radio Channel Selection menu select Automatic.
Step 12 : Click Update.
Step 13 : The next window may indicate that there are some problems. Resolve the problems then click Update.
