This seems to be a recurring problem at every recent IETF, regardless of host

there a way to VLAN these MAC addresses into the "get a clue" web page
redirector?
You can,(we've done it in the past) but since they're not actually
connected to the network when they're misbehaving it doesn't buy you much
until they fix their card, sleep their laptop, or reboot.
Having done some testing with various Operating systems wireless
implmentations, I think we can say with some degree of confidence the
instigating hosts are generally windows 2000 machines, it could be time to
upgrade because the winxp ndis wireless drivers won't do this without some
coaxing. Or, I'd be happy to hand out knoppix cd's to anyone who wants
one.
One would hope that none of these adhoc mode laptops have malicious MiM
intent.
It's seems unlikely that they are even aware. More than likely however
some of the people experiencing intermittent connectivty issues are the
source of a number of the problem hosts.
Good wireless hygiene starts with end users.

It would be nice if people did not run their WLAN cards in Ad Hoc mode.
Here are MAC addresses of some cards that I currently see advertising
various ad hoc networks. At least some of these were present also in
yesterday's plenary.
Network name MAC
Netgear 02-00-10-62-A3-6D
IETF64 02-00-31-9B-69-47
Netgear 02-00-61-76-D2-79
linksys 02-0C-F1-EC-CF-9E
TC_2 02-0E-35-03-D4-C4
IETF64 02-12-F0-00-33-FD
wireless 02-27-97-94-65-56
If you don't know how to check your MAC address or how not to turn off
ad-hoc capability, it may be better to turn off WLAN altogether.
Thank you,
