The problem is the WiFi service itself.
I learned 2 things about Match I wish I knew before signing up:
1) it is a data pig. You may find that streaming back your music takes as much data as a movie. Hence, you probably want to use your main (unlimited) the Wi-Fi (which means you're at home where your music is on your Desktop.. so, why stream?)
2) that WiFi has to be robust-very! Example: I have WiFi in my car strong enough to stream a baseball game (pic & sound)...but with Match, all I get is the Icon showing that the song is playing.. no volume. Minutes later, at home, on a WiFi partially down for repair (Cogeco), the same songs play perfectly. Same thing if I stream via my Hotspot on my phone's 4gl.
Hope this helps some. It won't if your home wireless network isn't streaming Match either. Could you boost your signal with 1 of those $30 gadgets? (We got one to boost wireless signal to a room). Please let me know if this helps.
Hoping Apple will find a work around.
