My son bought me an Airport Express to hook up to my stereo. It doesn't work with WEP security and when I tried to change my router to WAP I lost wifi and o fcourse internet connection on my laptop. I wound up restoring laptop and my desktop (which is hooked up via ethernet). I had to revert back to WEP which I understand is less secure. So, although my home network now works flawlessly again, I can't use the Airport Express because I'll just start the cycle all over again. Anyone out there have any suggestions? Please keep the explanation as simple as possible. Thanx.
