Thanks, Tim, but my problem wasn't an inability to connect to some domain. That's a logical issue with TCP/IP, so a step further down the road. I wasn't getting far enough to have an IP address from a local access point, let alone a fully established connection to a gateway where DNS whould start to matter.
My problem was more fundamental. The wifi radio just wasn't seeing any available access points. It was detecting no 802.11 radio signal, while Windows and Linux had no problem with the self-same hardware. It's possible it's some kind of channel scanning issue on either the 2.4 or 5 GHz bands, so something with the current driver. Maybe I should take the question to some mainstream Mac forum, but I'm not sure where that might be. This list is my go to source for all things Mac.
