The best way to keep the better client adapters (supporting 5 Ghz and
802.11n HT) from being dragged down by older, more inefficient radios
is to segment ESSIDs. It's certainly possible to run the same ESSID
("network name") with multiple access points, but as Rubin points out,
it just takes one slow adapter to sully the bunch.
This is why we run our 5 Ghz AP as "noisebridge-a", and our 802.11b/g
stuff as "noisebridge".

Actually, I think that the Cisco radios have been rock solid, but the
2.4 Ghz ISM spectrum not so much. If we had a lot more Ethernet and
2.4 Ghz APs sprayed all over the place, I don't think it would be as
big of an issue.

Here, here! Ubiquiti makes some great gear, and nearly all of it runs
OpenWRT swimmingly if you're into firmware hacks.
The Ubiquiti "AirOS" firmware seems much more geared towards WISPs,
and less towards 802.11 access.
