Unable to connect by Denon avr-1913 to the internet using my airport as a client to my airport extreme. I would love some direction on how to config the airport to act as an internet connection.

Are you using OS X 10.6.8 as your profile indicates?

Do you have the "square" version of the AirPort Extreme....or...is it round, like a flying saucer?

What version of the AirPort Express do you have? If plugs directly into the AC socket, check the label on the side of the AirPort for the Model No. Post back with that info.

The AirPort Express can be configured as a wireless Ethernet bridge. Apple calls this configuration a ProxySTA. To use the ProxySTA mode, be sure that your Express is running at least 7.3.1 firmware. Once verified, you can enable ProxySTA by going to the Wireless tab within the AirPort Utility and be sure that the following two items are set:

• Wireless Mode: Join a wireless network
• Allow Ethernet Clients (checked)

(Note: These setting are for AirPort Utility 5.x)

Start by temporarily locating the Express near the AirPort Extreme and performing a Factory Default Reset on the AirPort Express as follows:

Power off the Express and wait a minute

Hold in the reset button on the Express first and keep holding if for an additional 9-10 seconds while you simultaneousl plug the Express back in to power

Release the reset button after the hold period and allow a full minute for the AirPort Express to restart to slow, blinking amber lght

Make sure that the wireless is turned on your Mac

Open Macintosh HD > Applications > Utilities > AirPort Utiliity

Select the Express and click Manual Setup

Click the Base Station tab just under the row of icons and assign a device name, device password and adjust Time Zone settings

Click the Wireless tab

Change the Wireless Mode to read Extend a wireless network

Wireless Network Name = Same name as the AirPort Extreme wireless network

Check mark next to Allow Wireless Clients

Wireless Security = Same setting as the AirPort Extreme or WPA/WPA2 Personal

Wireless Password = Same password as the AirPort Extreme network

Verify Password

Click Update and wait a minute for a green light on the Express

Move the Express to the area where it will be needed and connect the Ethernet cable to your audio video receiver and you should be good to go. Of course, the Express will need to be located where it can receive a good signal from the AirPort Extreme

Sonos, a printer, a hard drive, or another device should not matter as far as the AirPort Express is concerned.

Temporarily, move your laptop near the AV reciever and move the Ethernet cable from the Express to connect to the laptop. Turn off wireless on the laptop and open your Internet browser to see if you can get can an Internet connection.

If you can, the Express is working.

Power off the AV receiver and try the setup again with the connection from the AirPort Express.

What works? The test I suggested, or is the AV receiver now working?

Anything that you can do to minimize distance and obstructions in the wireless signal path will help the connection speed and reliability of the setup.

For example, if the signal must pass through 2 normal sheetrock walls in a home, it will probably lose half of its strength and speed in the process.

When you have things working reliabliy, post back to confirm and mark this thread as solved so that it will help other users with the same question.

Thanks.
