Started pseudo-randomly changing wifi related settings, to see if it altered the situation. After picking a remembered wireless access point (one I'm rarely around), and deleting it, wifi started working again. So, that's relief.
As to whether or not Foxfi actually works on my S3, maybe I'll give it another try, after the memory of this experience fades a bit.

Yeah, I'd planned to give the stock ROM a few weeks, since I've never used one with the Samsung interface, before. The hosed wifi made me lean towards sooner, rather than later. But, now that it's working again, I'll probably stick with my original plan. The lack of control over my phone makes me twitchy, though, so I don't imagine it'll stay stock very long.
