I bought an Airport Express so I could connect my stereo and printer to it and get wireless printing and stream iTunes music. Everything was going fine until I recently found out that people were connecting to my wireless network in my house and using my internet connection. So I went to my router's setup page and made it so only devices with MAC address' I specify can log on to my Netgear Router. But since doing that my Airport Express' light has started flashing amber. My question is how do I allow my Airport Express to connect to my Netgear Router? (And also does it have to?) Because I don't want to extend my wireless network, I just want to access the internet using my Netgear DG834GT and get wireless printing fom my Airport Express. I tried using Apple's Airport setup in my Utilities folder, but it doesn't seem to find my Airport Express when scanning for networks. Any help would be appreciated.
