I have a problem to setup the airport express to stream music to my stereo. Here is the configuration I am using:
D-link ADSL router with wireless
This ADSL router is connected via ethernet cable to my desktop PC
Laptop with wireless connection connected to router.
Airport express connected to stereo

I have configured the airport express with my laptop to join my d-link network and that works fine. Now, when I try to do the same with my desktop, it cannot detect the airport although it is joined to the d-link wireless network.
Can anyone help to setup the airport via the d-link router ?
I have spent hours already but nothing seems to work.
