Thanks Mike. I really did appreciate your input.
What's interesting is that I've just reinstalled Raspian (due to a different problem, see here: viewtopic.php?p=1038276#p1038276
), and I connected like magic without doing anything in the way of preparation. Literally, I followed these steps:
1) Reinstall Raspian (wiping everything I'd had before, according to the Noobs warning)
2) Click the connection icon at upper right, select my router from the list presented, and type in my passphrase.
That was it - it took less than 5 seconds to connect and I had internet. I still haven't connected the ethernet cable; I used the wireless to do my sudo apt-get update and upgrade.
I now understand why I couldn't connect in the previous incarnation - I had the wrong MAC address in my router's access list. Had I gotten it right the first time around, I'm sure it would have done the same and this thread would never have existed. Like a great many software problems, it boiled down to the computer's pernicious habit of doing what you tell
it to do rather than what you want
it to do.
