RE: Wireless at IETF

2006-01-18 11:36:08
That is solving the problem for ourselves only.

802.11 is a classic case of what happens when unfinished technology is thrown 
at consumers.

Think about VLSI manufacture, thirty or so production steps each with a finite 
chance of error. If you have a 5% error rate at each stage your overall yield 
drops to 20%

Computers are much more complex than VLSI manufacture, the explanations of the 
technology are much worse than 95% accurate.

All my hardware is allegedly capable of doing WPA or 801.X. I have not got the 
slightest idea what I would have to do to enable it though, or how it would 
work, or what the authentication process would be.

It is unfortunate that the cryptographic failures in WEP obscured the much more 
significant usability failures. The wireless world still does not 'get' it.

The result is that 70% of wireless access points are open and can be used by 
Internet criminals to achieve anonymous access.

In addition to the content suggested below, I think a few 
words on "Why ad-hoc mode is BAD during IETF meetings" should 
also be included.  Not everyone knows the issues caused by 
ad-hoc mode (e.g. newbie attendees).

Regards and Happy New Year ...

I think (and suggested to the IAOC) that there should be an 
information sheet and / or web site for each meeting with 
information on how to determine Ad Hoc Mode, how to turn it 
off, etc., for all major OS choices.

Marshall

Tangential:
At the IEEE meeting following the IETF, someone asked me "how do I 
turn off ad hoc mode".

I was hard put to find an answer for Windows XP with the standard 
drivers (I use 2000 and a Cisco driver kit).

Suggestion: Make instructions *with screenshots* of how to 
turn off ad 
hoc mode on Windows XP available at the next IETF.

describes what 
seems to explain the appearance of IETF6x named 
computer-to-computer 
wireless networks at IETF meetings. Apparently, there is a 
feature  
that
has systems automatically advertise the last AP SSID after   
(involuntary)
disconnection. The slides are skimpy on details, but  
provide a bit 
more background than the usual "turn of ad-hoc mode"  
exhortations at 
IETF meetings.
