I 've always thought that was weird also.

I had a similar problem with one of my devices. i have two
Squeezeboxen, and a Slimp3/WET11. The Squeezeboxen are close enough to
my Airport that their signal was OK, but the Slimp3/WET11 was just too
far away, sometimes the signal strength there was less than 40% and it
just didn't usually work well.

What I did was to get another Airport Extreme and set up a Wireless
Distribution System (WDS) (actually I got 2 Airport Exreme Base
Stations as what I was using was an old "Snow", non-Extreme base
staton) Because of the placement of my second Airport, the two
Squeezeboxen got much better signal strength, and the Slimp3/WET11
signal strength improved very much also. Now I'm down to one main
problem, the Slimp3/WET11 is close to a microwave oven and every time
the microwave is used it interrupts the signal and the Slimp3 stops and
loses synch with the Squeezeboxen.

The short answer, from my experience may be that you may have to go to
a WDS in order to improve signal strength.

An UG to 802.11g might be nice, but I fear not much help unless all the
devices are G. I heard (not sure how it works) that on a mixed
network, that one 802.11b device slows the whole network down to B
speed (is that correct??).

I had troubles streaming 192kbps MP3s, this min bandwidth idea sounds
good, but I also fear a hardware UG would be necessary, then that's no
help to those of us who already have devices. Maybe if a HW UG were in
the works, it should not only include the min bandwidth that you
suggested, and also some larger buffer, though, I can see it all now,
press stop on the WWW interface, and the music plays on and on for
several seconds, until the buffer empties, that could be rather
strange.

Well there is that big red one in the upper-right corner!

OK, I know it's obvious: what about running a cat5 to the slimp3. You
run one for the AP-extreme. My connection is not interfered with short
of an EMP device, like a neutron bomb...

Unless of course the stop button on the WWW sends a "clear-buffer"
command to the slimp3/squeegebox, which it already does...

I agree. If the server is an old and underpowered one (as in most cases
our old PC end up being the slimserver) the larger buffers would help to
overcome server-too-busy-to-bother-sending-the-frame problems.
