Can't activate wlan0 in F7

[Joe Jerome]

Help!  We are trying to activate wlan0 on my son's laptop without
success.  We installed F7 from the KDE LiveCD.  Opening the Network
Device Control shows wlan0 inactive.  When trying to activate it, we
get:

  Cannot activate network device wlan0!

  Device wlan0 does not seem to be present,
  delaying installation.

Doing a 'dmesg | grep iwl3945' gives:

I have not tried to configure or use wireless hardware before.
Not sure what else to try or check.  Suggestions?
