Welcome to the the discussion forum!
went to the store and purchased another, new version (simultaneous dual band) and one more brand new airport express. I plugged the dual band extreme into the ADSL router and all is well and good within the range of that one airport. I get great, fast broadband.
The instructions below assume that you have a simultaneous dual band AirPort Extreme and an AirPort Express 802.11n.
Reference pages 43-44 in the
Apple AirPort Networks Guide for for info and Apple's instructions.
But *5$@ if I can extend it. I mean really, what is the difference between 'join and network' and 'extend a network'?
When the AirPort Express "joins" a wireless network, it can work with AirTunes, or provide a signal to a remote printer, but it does not do anything to "enhance" or "expand" the wireless coverage.
When the AirPort Express "extends", it does all of the above in addition to providing more wireless coverage in the area where it is located.
_On the AirPort Extreme_
Open AirPort Utility and click Manual Setup
Click the Wireless tab below the row of icons
Your Wireless Mode should already be set to “Create a Wireless Network”
Make sure there is a check mark next to “Allow this network to be extended”
Write down the exact type of Security that you are using as you will need this later to configure the AirPort Express
Update to save any changes and the AirPort Extreme will restart.
_On the AirPort Express (AX)_
You'll need to "hard reset" the AX by holding in the reset button until the amber light begins to blink more quickly.
I would recommend that you position the AX near your AirPort Extreme and temporarily connect an ethernet cable from your computer to the AX. After the Express is updated, you can remove the ethernet cable and locate the AirPort Express at its remote location.
Open AirPort Utility and click Manual Setup.
Click the Wireless tab below the row of icons
Wireless Mode = “Extend a wireless network”. If you don’t see this choice, hold down the option key when you click on the selection box
Wireless Network Name = the name of the AirPort Extreme network should appear as a choice. Click to select it.
Put a check mark next to Allow wireless clients
Wireless Security = exact same setting as your AirPort Extreme
Wireless Password = exact same password as your AirPort Extreme
Confirm Password
Click the Base Station tab to assign a name and device password for the AX, adjust Time Zone settings, etc.
Click the Music icon to enable AirTunes if you wish
Click Update to save settings. Disconnect the ethernet cable as soon as you see the message that the settings have been sent to the AirPort Express. The AirPort Express will restart in 20-25 seconds and you will have a green light if you configured it correctly.
Now the real trick is to find the right location for the AX. Start with it positioned approximately 1/2 to 2/3 of the distance between the AirPort Extreme and the area you want to cover. Then experiment by moving the AX closer or further away for the best compromise in signal.
Before you power up the AirPort Express, move your laptop to the proposed location for the AirPort Express. If you cannot get a good connection on your laptop, then neither will the AirPort Express. Look for another location where your computer connects well. That is a good starting point for the AirPort Express.
