How to connect airport express to Sony Bravia XBR9?

Sorry. The Express is set to "Extend a wireless network" not to "join."

was the express recognized when plugged in to the TV or did you have to do something prior to plugging the express to the tv?

The Express is recognized by the Airport Utility even when not connected to the TV. If you are not seeing the Express maybe one or more of your settings aren't matching your Extreme settings.

i only see the express when i connect it directly to the extreme router. i assume my extreme settings are correct since all my wireless devices are working properly.

As I said, I'm no expert on this. I don't understand what you mean by connecting the express directly to the extreme. When you open Airport Utility do you see both the extreme and the express in the left hand column with green lights on? If not, the only thing I could suggest is you check all your settings to be sure they match. If you can't get Airport utility to see both the only thing I can suggest is you list the settings on both and I can tell you if they match what I have.

basically the only way i see my airport express on the airport utility is when i connect one end of the ethernet cable to my router (airport extreme) and the other end to the airport express and plug it in. i then go through the set up, answer the questions and finally get the green light on the express. unfortunately this does not help me because i need to somehow get it to work with my bravia ( connection from bravia to express). sorry to bother you with this but i am about to give up.

Check the configuration settings of both your AirPort Extreme and AirPort Express.

For the AirPort Extreme:

Open Airport Utility, click Manual Setup
Click the Wireless tab below the row of icons
Wireless Mode....Create a wireless network
Make sure that there is a check mark next to "Allow this network to be extended"
Update to save any changes

For the AirPort Express:

Open AirPort Utility, click Manual Setup
Click the Wireless tab
Wireless Mode....Extend a wireless network
Wireless Network Name....same as your AirPort Extreme network
Check mark next to Allow wireless clients
Security....same setting as the AirPort Extreme network
Password....same setting as the AirPort Extreme network
Update to save changes

i did everything you said and when it came time to save my settings i get an error occurred while trying to access the apple wireless device. Make sure your network connection is valid and try again. i will try and reset my modem and see if this works. question if all this works which i doubt i assume next step is to plug the express to the TV and go through the network set up on the tv

These are exactly the settings that Apple publishes (reference pages 43-44 in the AirPort Networks Guide), and are the same as I am using right now to access an A/V device., so not sure what is happening there.

thanks Bob, I finally got it to work. i read from an earlier post where someone changed the multicast rate setting from 6 to 24mbps. i do not have that option, instead I have low, medium and high for multi cast rate. not sure if i should change that. i downloaded an HD episode and it played the last 10 minutes fine but when i restarted it looks like it went from HD to SD with several picture freezes

Unless you have a really strong, fast wireless connection, downloading video is going to really place heavy demands on the network. Remember, you're using wireless for this and losing some bandwidth in the wireless to ethernet conversion. Set the Multicast rate to low.

If you continue to get freezes, stutters, etc., you'll need to either connect to the Sony using an ethernet cable from your main router. Or, if this is not feasible, then ethernet powerline adapters would be the next choice.

thanks it's actually not bad now with the setting on low as you suggested. thanks again for all your help
