Here's what I'm trying to do.
Stream music from my windows 7 desktop in room A, to the stereo in room B with an Apple Airport Express.
My desktop has an i5 processor but was not wifi capable as we have all computers wired with an ethernet cable. So today I bought a D-Link wireless N 150 usb adaptor to plug into the computer that has itunes stored on it. It seemed to install itself OK. It can even see the next door neighbours wireless LAN
Then I connected the new Apple Airport Express with a minijack plug to the amp, and plugged it in.
Unfortunately the computer does not see the Airport Express at all, neither does Airport Utility. The Airport Express just flashes an amber light which tells me its not connected.
What am I doing wrong? By all accounts this should be a very simple set up.
