Guesswork much appreciated! But no. Moreover, while I don't know which neighbor of mine it is that considerately offers me an unsecured wireless LAN called "corega", this caters for my ancient Toshiba and my ageing iBook but not my new Mini. [but see update below]
My hunch is that it's one of the many settings in the Mini. Probably some setting that's obvious to you, but since I know about as much about wireless as I do about Sanscrit or neurology I'm quite lost.
Oh this is interesting: I put myself and the Mini to sleep last night and now that I wake both of us I see that "Wireless networks" is greyed out under the icon at the top right. So, System|Administration|Network Manager and there they all are. (All the levels are pretty low, though I'm starting to infer that they don't mean all that much.) I try my network one last time. This time it works
perfectly. Google, here I come! (Even after a decade of heavy use the Toshiba's keyboard is better than the Mini's so I'm using the former. No hard feelings, as the Toshiba cost four times as much, even before I consider inflation.)
Nervously, I put the computer to sleep again and wake it up again. It's now disconnected but I stay cool and don't touch anything: the tadpole starts swimming and I'm reconnected, all within seconds.
This is wonderful, of course, and I know I should be grateful. But I haven't made a single change to the network or to the Mini since last night. Maybe it's partly because I haven't previously attempted to connect any *nix machine wirelessly, but I now feel if anything more ignorant than is the (stereo?)typical Windows user. Indeed, I don't remember feeling this degree of bafflement and outofcontrolness since the days back in the last century when getting MS's latest OS to run usefully required either 386MAX or QEMM (whichever one I'd already bought usually didn't work this time around so I had to shell out for the other) and much earnest reading of the manual and crossing of fingers. Hmm.
