I have 6 WAP54G Linksys units, each w/ diff SSID. Have been pretty reliable.
I have found that the security settings will get reset occaisionally with
power/AC weirdness (sags etc). That cisco symbol/light is a source of
confusion --stay away!
Am looking to complete the wireless footprint this summer.

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
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.
