what a week. on thursday my corsair hx750 power supply up and died stone dead. i do not suppose i can blame it -- the power system here is awful, with frequent blackouts, generally preceded by a half dozen off-on cycles in quick succession. i have a biggish UPS between the mains power and the computer, but still . . .
so until the replacement arrives -- remember when there was a computer store on every block? -- i am on my previously reliable thinkpad X200, which got a little flaky when i upgraded it to debian stretch a few weeks ago. i now have most everything working, the exception being wireless. the nice little switch on the side of the machine is turned on, but no light on the wifi led and wicd reports no wifi signals, though there is certainly a wifi signal,from a router about 3 feet away that every other gadget in the house recognizes just fine.

i suspect that i'm missing something really obvious. for lo, these many years, the thing just worked. now it doesn't. wired network works just fine.

So just to make sure, wireless did work on your previous install? I have an X200 here, but still running 7.7

Open the PS and look inside. Does it have obviously swollen or leaking caps? If not, are any of the medium to small physically sized (14mm or taller, 8mm or wider) caps OST brand, any in the 220uF to 3300uF range? If so, it probably isn't the fault of your electric provider, but the manufacturer of that batch of Corsairs for choosing low quality components.

Do you have installed package firmware-iwlwifi? See https://wiki.debian.org/iwlwifi
Cheers

I do, and it is loaded. wicd isn't seeing it or, obviously, any wireless network.
part of the problem is that i got so accustomed to everything just working i've forgotten what to do when it doesn't . . .

it might be that it is soft blocked - check rfkill
# rfkill list
also it would be interesting to see what /sbin/iwconfig shows

I believe that any packages marked zd1211 plus firmware are actually for my usb wifi antenna, but have you tried them? Also, I seem to recall you wrote Intel, so look for any firmware related to that.
When all else fails, I search for any packages marked network, wifi, wireless, firmware, etc., and try them unless apt rejects them. Also, of course, I read the descriptions of the packages until something rings a bell.
Like you said, everything usually just works....

what is this? this looks like the wireless interface to me.
have you tried placing it in /etc/network/interfaces?

what network manager are you using?
wicd, though i have network manager installed as well.
i'll have to pick up on this later, though -- i have pictures to edit for three stories and two stories to write with a deadline in a few hours.
thanks, everybody, for your help. i'll report back after i've tried everything suggested here.

Okay, the computer is detecting the card and loading a driver for it. Things to check:
Does this card require firmware (Intel usually doesn't, but check anyway)? Is it present?
Does ifconfig show the interface?
Does rfkill indicate that the card is disabled?
Does scanning from the command line using "iwlist scan" from wireless-tools show your network?
Are there known problems with this card and the driver included in your current kernel version?
