Query: It works!

I purchased a different system first and returned it because it would work and tech support could only say "router incompatibity". Although this system did not "immediately" recognize my network, I went to the second step and used the USB connection to configure and it worked instantly. My only complaint is that the playlist does not allow you to shuffle or rearrange the music. I will definitely buy at least one more unit to add to my system.
