Mabonn I just went through the exact same thing with my Duet and have a thread posted here,

but the upshot is this, Squeezbox will not do 5G only 2.4G. If you are getting dropouts go to your routers admin page and change the channel it's broadcasting on. I did this and since I did basically no dropouts. When they do crop up again I just change the channel again. There are 11 channels so just see what works. It was a very easy fix once I found out about it.
