Hello I'm getting frustrated. I have a Powermac G5 that I bought in May this year. Unfortunately I did not order the airport card and bluetooth with it. Now I want to set up a wireless network for streaming music to my stereo and wireless broadband. I bought an Addlogix wireless-g usb network adapter on the recomendation of the shop assistant - I had also seen it on the internet advertised as being very good with Mac OS. Anyway - there's not much in the way of instructions with it and I really don't know how to work it. From what I can tell, it seems to be working. What I do know is that after using the Airport Setup Assistant (with the Airport Express attached to the powermac via cable) it tells me everything is OK but when I open iTunes, there is no menu for the Airport location. The thing is that last night, I got it working for a while and had wireless internet access for a while, then not, then back again - frustrating. However, even though I could "see" the Airport location in iTunes, it would simply not connect to it. So after stuffing around a bit more, nothing worked and I gave up. This morning I did a factory reset on the airport express and set it up again with the Airport setup assistant. No luck, no wireless internet, no airport location in iTunes. Aaaaaaaaaarghhhh!!!!!!
