[Web4lib] Viral SSIDs in libraries?

[Rosenberger, Luke E]

Are any of you aware of libraries who have had problems with sudden and
dramatic growth of wireless traffic on "viral" ad-hoc wireless SSIDs, as
described in the following article?

http://www.wlanbook.com/free-public-wifi-ssid/

For several days now, the signal for our campus infrastructure wireless
network inside our library and lecture halls has been very unstable.
After analysis, campus networking is telling us that there are nodes
sending out bursts of heavy traffic on ad-hoc networks with SSIDs like
"hpsetup" (even though we have no wireless HP printers anywhere near
here). These bursts of traffic are creating so much "noise" that they
are intermittently knocking users off of the real infrastructure
network.  Tracking down the "source" of this traffic has been elusive --
which makes sense if we are experiencing the phenomenon described in the
article, because if that's true there probably are multiple, constantly
shifting sources of this traffic.

Both library and campus IT are puzzling over how to address this problem
-- even if we start educating users to switch their wireless configs to
"infrastructure-only" mode, it will probably not not solve the traffic
interference problem, just slow the "viral" spread of these ad-hoc
networks.  Is that the best we can hope for?

Thanks in advance for any suggestions.
