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

Thanks for all your help. I tried changing power levels, channels, and re-assigning IP addresses ( traffic priority?). In the end, the thing that made the most difference was re-positioning the router from the desk down to the floor so it is facing the stairwell. So far, no dropouts either on my computer files or on the Internet radio stations, after about a half-hour of listening. So far, so good. If I start having problems again, I may bite the bullet and get a dual band router. Thanks again. I am a happy camper. ...Matt
Good!

If problems recur, another alternative to consider would be to retain the 2Wire device, but disable its wireless function and add a separate wireless access point, which in turn would be connected to the 2Wire via an ethernet cable. I've always preferred that sort of arrangement, because of the flexibility it provides with respect to both selection and placement of the wireless device.

I currently use an EnGenius N-EAP350 wireless access point, which I've found to be an outstanding performer (although it is single-band). I use it in conjunction with a SonicWall hardware firewall/wired router, and a cable modem supplied by my ISP.

Dropouts again! Went almost a week with no dropouts. Then today I downloaded a Dave Brubeck album from HD Tracks. It's FLAC 24 bit 88.2 kHz. It drops out every minute or two. Internet radio and my CDs (FLAC 16 bit 44.1 kHz) are still ok. Any suggestions ?
Hi Matt,

What software are you using to play back or serve the file? Look in its Options or Preferences menu to see if there is a buffer size setting that can be adjusted. If so, increase it. The size may be expressed in terms of an amount of time, probably seconds.

Or perhaps, as I indicated earlier, the AE or the Marantz includes a buffer whose size is adjustable (I'm not familiar with either component).

Is it possible that there could be a problem with the files themselves? It might be worth it to burn the files to a CD. If the drop outs are on the CD then you may have some damaged downloads.
