Hi William,

A good place to start with diagnosing connectivity issues
is to install the NLANR beacon. This will give you an idea 
as to how your reachability compares to other sites.

Others on this list can help you with switch and router 
configs once you've measured how bad your problem is.

P.S. If you're looking for a low bitrate audio-only source 
that is known to be live, try "UO Presents KWAX Classical 
Radio" (224.2.246.13/30554)
