Need help with Apple Airport Express


I bought an Apple Airport Express so I can connect my Marantz SR-7007 to my wireless network. I want to use it as a wireless client. I have an iMac and AT&T uverse is my Internet provider. The Airport Express configures properly ONLY IF it is connected to the router with an Ethernet cable. I can not get it to work with the Wireless network. I've googled directions and tried everything. Can anyone help, or do I have to have an Apple tech come to the house ? Thanks

Now that you have the Linksys router up and running, you'll need go through the setup for the AE again to join the Linksys Wifi network.

Also, the AE only supports 44KHz output, so anything higher resolution gets down-sampled.
Matt, AE is by default set to receive both 2.4GHz and 5GHz. I use Linksys as two separate networks with different names: 5GHz with MacMini and AE, 2.4GHz with other computers. I could set my MacMini to transmit both frequencies but couldn't find how to connect Linksys on both simultaneously. Perhaps giving networks the same name would do it? I ended up with separate 5GHz network for music but adding 2.4GHz should make it even more immune to dropouts.
Hello Mrvco,
Yes, I performed the setup for the AE to work wirelessly with the new Linksys router. It works for Internet radio, but is unable to access my iMac music library. Before I got the Linksys, the AE was connected wirelessly to the 2Wire gateway modem/router, and it was able to play both radio and media from my iMac. Can't figure this out. ...Matt
Matt, It is not that AE cannot see your music library, but perhaps program you use to transfer music (like Itunes) cannot see your library.
Kijanki, I will look into the 2.4 and 5 GHz issues you brought up. I am using Logitech Media Server to transfer music. This still works with my Squeezebox connected wirelessly to the Linksys ( both radio and library ).
Thanks for all your help. I will keep working on it and report back later. ..Matt
