airport express hard wired into airport extreme

Configure the Express as a bridge.

Internet Connection > Connection Sharing: "Off (Bridge Mode)"

Suggest that you follow the steps below:

Close AirPort Utility if is open.

Disconnect the Ethernet cable from the AirPort Express.

Perform a Hard Reset on the AirPort Express by holding in the reset button for 8-10 seconds and then release. Allow a full minute for the Express to restart to a slow, blinking amber light.

Connnect the Ethernet cable to the WAN "O" port on the AirPort Express

Click the AirPort icon at the top of the Mac's screen and wait a few seconds. Look for the heading of New AirPort Base Station. Just under that, the AirPort Express will appear. Click directly on AirPort Express.

AirPort Setup will open automatically and then take a minute to analyze the network and announce that the Express will be configured to "Extend" the network.

Enter a device name for the AirPort Express that you want to use and click Next

Wait a minute or two while AirPort Setup configures the Expresss. When you see the Setup Complete message, click Done.

You are done.

Did the trick for me, thanks Bob.

I too have the same setup (I think) as what was described. I have a comcast Netgear Modem/Router performing DHCP/NAT. Coming off of one of the 4 LAN Ports of this modem/Router is connecting my Apple Extreme (Set in Bridge Mode). The AE is providing my WIFI network and doing very well. I have a Netgear 8port Gigabit switch that I have connected to one of LAN ports on the Apple Extreme to be able to provide Ethernet connections to PC and other devices that need access to the network. I want to extend the coverage of my WIFI network with an Apple Express. I have run a Cat6 ethernet cable to the location where I want to place my Express to extend coverage and connected into one of the LAN ports on the Apple Extreme.

My Question is how do I get this to work with the setup as it is now? Will it even work? Or, Should I setup the Apple Extreme to perform the DHCP/NAT and put the Comcast Netgear Modem/Router into Bridge mode?

See your other post. Please.....do not double post, as it makes things very confusing.
