How can I join Airport Express and 2Wire 3600HGV to extend wifi?

Question

I to join an Airport Express to the wifi network from my AT&T 2Wire 3600HGV router to extend the wifi signal.  I know it is not SOP to link an AX to a non-Apple device like this.  I found instructions ( http://fsdeviations.blogspot.com/2012/09/howto-2wire-3600hgv-airport-extreme.htm l ) for joining an Airport Extreme to the 3600HGV.  Has anyone used this or a similar approach with the Express to join and extend wifi from the 3600HGV?

Answer 1

Connect an Ethernet cable from on of the LAN <--> ports on the back of the 2-Wire modem/router to the WAN "O" port on the AirPort Express.
Power up the AirPort Express for a few minutes. The indicator light on the front of the device will be slowly blinking amber at this time.
On your Mac......
Open Finder > Applications > Utilities > AirPort Utility
Click on the Other WiFi Devices tab
Click on AirPort Express
The setup utility will open up and take a minute to analyze the network, then suggest that the AirPort Express will create a new network....which is the correct setting.  The window will look similar to this illustration:
For Network Name......type in the exact name of the wireless network that the 2-Wire is providing......IF.....you want to "extend" the 2-Wire network and make one "big" network.  If you want to have the AirPort Express provide a different network, type in the name of the network that you want the AiPort Express to provide.
For Base Station Name....type in a device name that you want to call the AirPort Express
Password......If you want to extend the 2-Wire network, then type in the exact same password that the 2-Wire network is using.  If you want the AirPort Express to provide a different network, type in a password that you want to use with the network that the AirPort Express will provide
Verify......verify the Password
Click Next, and the utility will set up everything for you automatically.
When you see the message of Setup Complete, click Done.  That's it. There should be a green light on the front of the AirPort Express at this point.  You can configure other AirPort Express devices in the same manner.
