The password is ten digits. I've tried passphrase,
ASCII and HEX. None have worked. The owner says that
the password is ten characters long and consists of
the phone number.

Frankly, I'm baffled. If I determine that my settings
are correct then I will move on (there are lots of
places with free wifi around). But if it could be
something on my side that needs tweaking then I would
like to troubleshoot longer. Is it possible that there
may be some setting on the coffee shop side that I
have not considered? (Assuming, of course, that the
owner has given me valid settings.)
