If you are running a 10Mb 4 port hub, you'll probably never get more
than 2.5 megabits of xfer no matter what you do. A hub divides the
total bandwidth (10Mb/s in your case) between all the ports evenly. A
10Mb/s switch on the other hand allocates 10Mb/s **per port**.
As for your download speeds, are you certain you are getting 30Mb/s?
That's actually honkin' fast for a home connection of any type. @home
limits you to 3 Mb/s, your son I suspect was getting xfer rates in the
hundreds of Kb/s range. It almost sounds normal to me...a 10 Mb hub
will not win many speed contests...except ones against a sneaker-net.
I suspect that .wav performance would be quite choppy, due to the fact
that you are trying to stream/play files that have file sizes best
estimated in ten's of megs...quite a challenge for a 2.5 Mb/s pipe.
You can check your for collisions during a big transfer though, they
will bring hubs to a near standstill without much effort. Another thing
to suggest would be cable swapping, unless you are quite sure you have
good cables, they can cause trouble quite easily...were they bought or
built?
