Re: Wireless in buildings... Thanks Wes, that’s encouraging! I think part of our experience has been the mixture of B/G (“dumbing down” to B speeds). Looking forward to all G/N next year. Has anyone had issues with this mixture? Does G “dumb down” N traffic in the same way?

I have a Thin Client laptop lab that runs off of one of those access points. We have had all 24 units going at once as well as others attached to it and didn't have any problems with speed or capacity.

Re: Wireless in buildings...
We have a similar setup (Linksys WAP54G), but I am skeptical about the capacity of these when our portable labs increase from 12 to 20 next year. Each lab has a dedicated access point. Does anyone have thoughts about the capacity of these APs?

I have found that the security settings will get reset occaisionally with

confusion --stay away!

Bryan,

What you want is "Roaming".  It is a protocol where the wireless access
points hand off a moving workstation to each other, taking over the
communications for that workstation.  It involves the access point that just
acquired a workstation updating the ARP table of every device on the network
with it's MAC address, so the packets will now come to it instead of the
access point that just gave up the workstation.  One of those seemingly
simple things that really is quite amazing when you see it work.

Once you are using access points that support roaming you can have a single
SSID, all of them use the same channel (and have identical security
settings).  The broadcast ranges of the access points can overlap (should
overlap if you want uninterrupted coverage) and the workstation will select
the strongest signal when it starts up, picking up another signal once it
reaches a weakness threshold.  The switch over is noticeable on the
workstation, if you are doing a download you will see it pause for 2 or 3
seconds.

I have done 3 buildings very economically with Linksys WAP54G access points
($70).  They function well and are inexpensive enough to have a spare on
hand for fault tolerance.  To manage them I have a web page that has a link
for every access point described by location.  They have a lit cisco symbol
on the front that if pressed reprograms them to some brain dead setting
Linksys thinks you want, so I cover that to keep little fingers away.
