Yep, it's an application-level problem now. If it was below that,
Firefox would have reported something like "Unable to connect", instead.

You can specify the channel you want with 'iwconfig', if I recall
corectly; that gives you the AP that you prefer.

Jeff, you clipped too much of what I'd said and lost the context as a
result. I didn't say that you should have *never* tried to use that
coffee shop; what I'm saying is that, once you discovered that their
setup was broken, contorting yourself to fit their straitjacket
(particularly when you're uncertain of how well your own system is
working) makes no sense. If you want to do effective testing of your
wireless, you need a simple, working, _compliant_ wireless AP; trying to
connect two unknowns is a recipe for lots of self-imposed pain.

I hadn't realized that; interesting.

That sounds really great, Jeff; I'm looking forward to seeing it!
