Like a virus, certain pieces of information enter the collective consciousness, and they grow with repetition. I recently decided to debunk wireless-related myths, inspired in part by Joel Snyder’s recent column. For my I initially thought about writing specifically about wireless LAN security myths, but tracking down all the wrong-headed data that has entered the conventional wisdom and debunking it turns out to be a bigger project than I’d initially thought.
The moral of the story is that if you run a network, be sure to check up on received wisdom before following it. Just because it was written down at some point does not mean that it is still true.
