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

Mabonn, I had impression that AE is limited to 16 bit, but if it is the case you should have no sound at all.
Kijanki, I had more dropouts after I thought I had eliminated them. So, I went to Best Buy and bought a Linksys 2500 dual band router. Got it set up today, and it seems to be working. If it goes an entire week with no dropouts, I'll declare victory. The one question I have (for now) is this: Wireless devices are given the option of joining the secured network with password or as a guest (unsecured with no password). How do I disable the "guest" option? Thanks, Matt
You will find in System-Router menu: Setup, Wireless, Security etc..

Select Wireless. It will open Basic Wireless Settings, Wireless Security, Guest Access etc. Select Guest Access. It will show option "Allow Guest Access" Yes/No - select "No".

Guest possibly cannot change settings but I have no use for this option and disabled it.
Kijanki, Thanks. One more question..... I got it working for Internet radio, but the AE no longer accesses my iMac music library. The Squeezebox DOES access my iMac library. ?? Thanks for your help. .. Matt
