Comment(by carrano):

 We should do some sniffing.

 Just some uselful info: scanning can be passive or active. In passive
 scanning a node will listen to every channel, in sequence, collecting
 beacons. In active scanning a node will issue a probe request on each
 channel. This probe requests may indicate a specific SSID or sent out to
 the broadcast SSID. In the latter case, all APs and ad-hoc networks (one
 of its nodes) will respond to it.

 To my best knowledge, NetworkManager will ask for an active broadcast
 scanning every 2 minutes or so and this is the probable source of
 information for the user interface. Can someone confirm this? It's also
 important to note that "iwlist scan" will most probably return different
 results every time it runs. This is expected.

 Specifically on the media lab APs, We have to keep in mind that there is
 more than one AP responding for this SSID ("media lab 802.11") and I don't
 know how this is handled in the UI. Btw, when you iwlist scan do you see
 more than one "media lab 802.11" ap?

 And have anyone seem what you described happen to another AP? I didn't but
 I do not use other ssids as regularly.

 Finally, regarding the "stops transmitting beacons", one of the media lab
 access points was interpreted by kismet as cloacked (ssid removed from the
 beacon). This was not configured in the AP, so it was either a
 misinterpretation of the kismet drone or a bug in the AP - both possible.
