I have a first gen Express and configured it to creat a network.I have a 4 th gen Extream and configured it to extend the network(It also has my backup drive and printer pluged into it at the far end of the house).How can I determin it is extending the network it seams to be working it has a green light but the wifi signal is not showing up under the wifi signals available on my laptop and I am only seeing the Express under the available wifi's to be connected to and the signal is low.


Thank You

    On a Mac laptop........


    Locate it near the AirPort Express

    Hold down the option key while you click on the fan shaped AirPort icon at the top of the screen

    Look for the BSSID and jot down the last few characters


    The BSSID is the AirPort ID of the device to which you are connected


    Now move the laptop very close to the AirPort Extreme and perform the same BSSID test


    If you see the same BSSID as the AirPort Express.....your Mac is connecting to the AirPort Express....and the AirPort Extreme is not extending.


    If you see a different BSSID......then the AirPort Extreme is extending correctly.


    Keep in mind that when you have an extended network, you will only see one wireless network to join.....not two.

    It is easy to see that your two devices are not on the same subnet,or in more simple terms, they are not on the same network.


    One has an IP address of and the other has an IP address of If both were on the same network they would both have IP addresses of 192.168.1.x


    You also have different security settings as well.


    Are you trying to connect the AirPort Extreme using an Ethernet connection from the main base station or using wireless only?


    Let's find out what generation Express you actually have there to start.  Look on the side of the Express for the Model No.


    Post back with that info.

    OK, that model will work.


    Open AirPort Utility, select the Express, then click Manual Setup

    Click the Wireless tab below the icons

    Make sure that there is a check mark in the box next to "Allow this network" to be extended"

    Update to save any changes


    The settings on your AirPort Express should look similar to this:

    Post back when done with the Express and we will continue with the Extreme.

    Next, perform a Factory Default Reset on the Extreme as follows:


    Power off the Airport Extreme by pulling the power plug from the back of the device

    Wait a few minutes

    Hold in the reset button first, and continue to hold it in for an additional 9-10 seconds while you simultaneously plug the power plug back in

    Release the reset button after the hold period and allow a full minute for the Extreme to restart to a slow, blinking amber light


    Temporarily, move the AirPort Extreme to the same room as the AirPort Express


    Configure the Extreme again by selecting the Extreme in AirPort Utility and clicking Manual Setup


    Click the Base Station tab to name the device, estblish a device password and adjust Time Zone setttings


    Click the Wireless tab


    Wireless Mode = Extend a wireless network

    Wireless Network Name = Same name as the AirPort Express network

    Check mark next to Allow Wireless Clients

    Wireless Security = Exact same setting as the AirPort Express

    Wireless Password = Same password as the AirPort Express wireless network

    Verify Password


    Click Update and wait 25-30 seconds for a green light


    Move the Extreme to a location where it can receive a strong wireless signal from the Express and power it back up


    Perform the BSSID tests again to verify that the Extreme is extending the wireless signal
