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.
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?
