View Full Version : MULTIPLE WIRELESS APPLICATION (802.11g)

I have written before and had many helpful replies about setting up a
spa / health club application running multiple Squeezebox units on a
wireless network. The consensus at that time was that I would be better
using a 10/100 wired Ethernet LAN as there could be band-with problems
with multiple units streaming together.

All building work has now been completed and the quotes to retrofit the
LAN wiring are rather high but of more concern is the fact that the
installation may cause significant damage to our ceilings and the wiring
contractor will take no responsibility at all for any damage. This is
pushing us back towards a wireless installation.

Today tech support suggested using an 802.11g wireless router with a
wireless access point hardwired to each Non-Wireless Squeezebox. There
would be 5 to 6 squeezeboxes. Hardware cost wise this seems an economic
solution.

I have looked at the Xtreme G range from D Link and am thinking about
the DI - 624 Router (108 Mps) and D Link suggest using a G - 820 network
adaptor at each Squeezebox. Tech support had suggested an AP connected
to each squeezebox instead of a Network Adaptor. I am unsure of the pros
and cons of each as I am a real wireless newbie !

The maximum distance between Router and a Squeezebox / AP would be 65
feet and at most there would be 2 - 3 internal plaster board walls
between the straight line points. All would be working at the same floor
level.

We would rip all files to MP3 at 128 Kbps max and intend using Edirol
powered speakers at each location.

Tech support suggested someone out there may have experience of using
such a wireless "g" set up and I would welcome any comments on the
functionality or pros and cons of the system set up we are now
considering. It's time to make our mind up !

Thanks a lot.

In infrastructure-based Wi-Fi, there are

-- Access Points (APs), which are a kind of hub in a star
configuration, talking to Stations (STAs), and

-- Stations (STAs), which are the clients that can talk to Access
Points.

A DI-624 is (contains besides the router) an Access Point. A G-820 is
(contains) a Station, so it will be able to connect to the DI-624.
Another Access Point will *not* talk to the DI-624 over the air, unless
there is a mode to run it as a Station (at which point it ceases to be
an Access Point).
(D-Link further confuses the issue by calling Stations with Ethernet
ports "wireless bridges", a term that often was used for something
entirely different before.)

So I think the "Tech support" advice is incorrect, if taken at face
value.

The confusion may stem from the following additional complexity.
Access Points can be connected to a Distribution System, which
originally always was wired (several APs connected to one Ethernet);
nowadays there are various forms of wireless Distribution Systems which
allow specific Access Points like the Apple Airport Extreme (and
Express) to be both clients to a master Access Point and Access Points
in their own right. However, both the master Access Point and clients
that use it as a wireless Distribution System currently must be from
one vendor (or at least one supplier of firmware); I'm not aware of
such an offering from D-Link.

So, in summary, make sure that you do have an Access Point (the DI-624
contains one) for the server side, and the other ends can connect to
Access Points (the G-820 and other "client adapters" can,
run-of-the-mill APs can't).
