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

Markhyams, I hear you. I have a ST in my 2 channel system, in a different room. I bought the AE for my HT system. If I had it to do over again, I would probably get another ST. I may upgrade at some point. Thanks, Matt
It works, but it stops occasionally (for buffering?). Is this a problem with the AE, or do I need to increase the Internet speed ?
You most likely get dropouts caused by interference like microwave oven. Changing channel helps but I ended up replacing router with dual band Linksys. My AE operates now only on 5GHz where there is very little traffic since dual band routers are not very common. In addition any outside interference is suppressed since 5GHz does not penetrate walls very well.

AE is dropping first second of each song with some DACs, that are not fast enough to re-sync. My Benchmark DAC1 doesn't do that but remedy for this is to crossfade songs in the player. Itunes has this option.
Hi Kijanki, Thanks for your reply. I have a 2wire 3800hgv-b gateway router. How can I find out if this is dual band ? What model Linksys router do you have. ? Thanks, Matt
Matt, I read your modem's data and it doesn't say it is dual band meaning it isn't (most common).

It also looks dated since it isn't 802.11n. My Cisco Linksys E2500 is only a wireless router while 3800hgv-b is a gateway (has modem inside). I had similar 2-wire modem before and started having internet dropouts (perhaps age - old caps). Decided on separate modem and router. Modem I use (Motorola 3360) works like charm (no dropout ever) but had poor reviews since previous versions were overheating (this version has better airflow). The reason for Motorola is support from my provider - AT&T that lists this model. Setting Modem-Router can be a little tricky and should be done the way they recommend it but it is easy if you follow steps. Linksys has other versions like for instance E2700. You need to find out what you need (USB ports etc.). It isn't high power wireless, so if you need distance over walls something else might be better (or use repeater). Mine is pretty much in the same room (loft). Hope it can help you. I'm not a computer wiz but I know who is - Almarg, in case you need help. He also has better overview of the situation and can recommend if you need the change.
