I just recently moved which caused me to need another airport express. I had no problems joining my current network. I chose the option to extend my network so I could have better internet signal along with play music to my stereo from iTunes. Everything seemed to be working great until I started playing music. I was getting alot of dropped signals which caused my music to cut out frequently. I decided to change the settings and only use the new airport express to play music through, no internet. However, when I chose this option itunes and my imac were unable to "see" the new airport express. Does anyone have suggestions for me on how to fix this? Thanks.
