Heh :-) Well, I ran the iwlist scan a number of times to make sure I
didn't just get some freak results.
What I'm looking for is the answer to two questions:
- what performance can people reasonably expect, especially when
comparing to other devices ?
- do we have a problem, i.e., does our device perform consistently
much worse than other devices using similar technology ?
Obviously, results will be fuzzy around the extremes, but that technology
isn't entirely unpredictable either.

Yeah, see the 0dBm and -98/-95dBm I got from my laptop ;-)
