To Brian Morrison and Steven F. LeBrun,

Steven F. LeBrun, I appreciate your suggestions.  I hope what I tell Brian below, is in keeping with what you suggest.  Your quote:
"There are 10 types of people in this world, those that understand binary and those who don't."
with it's quirky humor, is great!  I have a mathematics degree from the University of California.  I am familiar with binary,octal,decimal and hexadecimal number bases.

Brian, you are correct, I should have subscribed to the Fedora NetworkManager list, instead of the laptop list. My mistake!  I will probably subscribe to that list tomorrow and document my wireless problem.

I went to 'System -> Administration -> Add/Remove Software' and hopefully downloaded
'Firmware for Intel Corporation PRO/Wireless 3945ABG'

I have never used the 'Add/Remove Software' administrative tool before, so I did not what to expect.  I am not sure I downloaded the driver to my computer.

This was my last message on the '/var/log/messages' you told me to check.
'Jul 26 12:49:07 localhost yum: Installed: iwl3945-firmware-15.32.2.9-1.fc11.noarch'

Immediately after reading that message, I went to 'System -> Administration -> Network', but when under the 'Devices' tab, when I clicked on the 'wlan1' entry, the 'Activate' , on the menu bar above, was grayed out.  I could find no way to activate 'wlan1', which had my Intel Corporation PRO/Wireless 3945ABG card.

Any further suggestions or comments?  I definitely appreciate the help that both of you have given me so far.
