on updated f12 system, wireless suddenly vanishes

[Robert P. J. Day]

  a bit of a mystery here ... after wireless has worked just fine on
this laptop for months on end, i show up at a friend's place after
work, fire up the laptop, expect to connect to his wireless same as
usual and ... nothing.

  check the network settings thru network manager and not only is
wireless not active, the setting is greyed out so i can't even select
it to activate it.  how odd.

  "ifconfig -a" shows a wlan0 interface, but it's not up.  then
there's iwconfig:

wlan0     IEEE 802.11bg  Mode:Managed  Access Point: Not-Associated
          Tx-Power=off
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off


if i try to scan with that interface:

# iwlist wlan0 scan
wlan0     Interface doesn't support scanning : Network is down
#

  and

# ifconfig wlan0 up
SIOCSIFFLAGS: Unknown error 132
#

  time to start googling, of course, but all of this came on suddenly
and for no apparent reason.  thoughts?
