If neither, then you had a false alarm from Prime.

In your environment, do you have 11k and Assisted Roaming Prediction

I can't really get any usable advice from Cisco because their engineers
tend to fall over when I tell them how many APs I'm running in a single
broadcast domain. :-)
Am I the only one still out here on this limb?

that they
are similar, or just guessing at AP placement.
BTW, there is a pricing promotion on the ten-pack of AP1142s through the
end of April. I think it's 10% off on the APs but the power injectors
are not discounted so its a little less than 10% off overall.

timely manner sometimes up to 90 seconds. As you can imagine, this
caused all sorts of problems. I've got the Cisco bugid here somewhere
if anyone needs it. This was fixed in rev 4.2.112.0. No problems
since.

With the Wireless Lan Controllers, you only have to trunk the multiple

You can also remove the Manufacturer Installed Cert (MIC), which then
requires you to generate self-signed cert and then configure the WLC to
accept that self-signed cert. Been there, done that. :-)

on our Cisco APs with no security and
broadcast SSID. This traffic is bridged at layer two to a local WISP
that provides DHCP, DNS, AUTHn, AUTHz, etc. The guest users end up in
the ISP's address space, not ours.
I think GSU is even using the same WISP that we do.

but Apple's refused to associate. If you turned off WEP, it worked,

Anyway, IOS 12.3(7) fixed the problem. We're happily running

that Airwave engineers are so responsive to our requests and needs and
that's why we dropped the big bucks for a monster server and another

Ask me in a few weeks if the new server is noticeable faster. Crossing

just walk around and look for them?
If the AP is up and working, you might try using Airmagnet or
Netstumbler to search for the wireless MAC address and go to where the
signal is strongest.
