wireless chipset in it. I cant recall which one.



The broadcoms in the Linksys wrt54gl's support meshing using WDS, which
works well but is slow. I was using that to get network out to my shed for
quite some time. It does mean that all the comms (client -> ap ->
other ap
-> Ethernet) are done on the same channel so thruput was 5 or 6 megabit
on a
good day.



I find that most people that claim their house to be covered by a single
accesspoint have problems at one end or the other of it with the speed
dropping to sub 6 megabits and pauses as the speeds negotiate up and down.
I
don't consider that coverage since its not working reliably.

IMHO wifi "dropouts" in people own homes is likely to reflect the
low
price point consumer equipment is made down* to - in terms of the
chipsets, firmware and 'antennas' (if you can those little twigs
that). I worked with this stuff for many years (since the original
pre-802.11 equipment and before the term "wifi" was used) and
fitting
it to industrial environments we'd expect better performance than
often people seem to be experiencing nowadays in their homes. Okay,
so that was shops & warehouses but often harsh environments for rf
(very solid walls, liquid etc,). I dream to be able to afford a home
& grounds large enough to really warrant more than 1 AP.

I'm sure some people *do* have very very solid walls but most of the
time it to either be the quality of the kit (APs and mobile devices)
or
the other explaination would be general congestion of the band - with
only 3 non-overlapping channels, most APs only capable of pumping out
their maximum allowed signal and houses not far apart there *will* be
overlap. DECT phones, wireless video senders, bluetooth phones (low
power and interoperate but there's so many of these... 4 in our little
house alone) etc,....

The Sonos kit is a premium product, not like most electronics which is
a race to the cheapest price. Also if they are meshed then it wont
have been "off the shelf". Both factors which suggest the
wireless
implementation is likely to be of a higher quality than a cheap device
with Wifi tacked on.
