ITunes and Wifi - More Details

Again, if the wifi is on and connected to a server or turned off, iTunes works fine. Plays for hours without a glitch, playing online radio, MP3s, or Apple Lossless format (my choice since I play through external stereo systems). If I turn off wifi when the bug occurs, then stop and restart the audio, it plays fine once again. I use 4.7 because. the more recent versions do not work with my CD burner. Clearly though, there is a connection between the iTunes glitch and the unconnected wifi.
