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
'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:
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.

If your network device is controlled by NetworkManager, you will no be
able to activate or deactivate it using system-config-network (the
command you reached through the System menu).
Run system-config-network, select your wireless card and then click on
the edit icon. In the dialog page/General tab that appears, the first
checkbox item is "Controlled by NetworkManager". If you deselect that
checkbox, you can activate the wireless card back in the main
system-config-network dialog (devices tab).
Also, did you reboot your laptop after installing iwl3945? I am not
sure if it is necessary but I always do it after installing new drivers,
especially if they do not work after install before a reboot.
Are you familiar with the /etc/sysconfig directory? There are two
subdirectories, networking and network-scripts that are related to
running networking. I do not advise editing any of these files directly
unless you are sure of what you are doing. There are applets like
system-config-network that will do the modifications safely and
correctly since changing one parameter may require changes in multiple
files and even the creation of new files.
You may want to look at the files there to see if the data looks
correct. Your system should have a file ifcfg-wlan1 (in multiple places
in /etc/systconfig/network-scripts and
/etc/sysconfig/networking/devices). There should be an ifcfg-* file for
each of your network devices. That fact that your wireless card is
named wlan1 instead of wlan0 suggests to me that there is something
different between our configurations. If you notice values in these
files that does not look correct, find out how to change the values
correctly (probably with system-config-network or a similar tool).
Do you know why your wireless adapter is wlan1 instead of wlan0? Was
this an option you selected somewhere? Is there also a wlan0?
Your other source of information is your boot log and messages.log.
During each rebooting of my laptop, my wlan0 fails to initializes and an
error message is reported. If you post the section of you messages log
file and boot.log (if your boot.log is not empty) relating to
starting/activating your wlan1, it would help.
From my boot.log:
Bringing up interface eth0:
Determining IP information for eth0... failed; no link present.
Bringing up interface wlan0: Error for wireless request "Set Mode"
SET failed on device wlan0 ; Invalid argument.
Determining IP information for wlan0... failed.
There is no cable connected to eth0 so its failure is expected. The
"Set Mode" error for wlan0 is a problem with one of the statements in
one of the ifup-XXX scripts and appears to be harmless in this case.
When NetworkManager starts up, it successfully starts my wlan0
connection to my intranet, getting an IP address from my DHCP server.
This all appears during a reboot.
Let me know if this helps or you still need or want more help. It is
after midnight and I am not sure how coherent I am at the moment. :-)
BTW. I like the "10 types of people" quote; I first saw it on a t-shirt
BTW2. When I run "lsmod | grep iwl", I get the following:
[root@tardis default]# lsmod | grep iwl
iwl3945 125016 0
mac80211 164720 1 iwl3945
lib80211 5064 1 iwl3945
cfg80211 30604 2 iwl3945,mac80211
The first column are modules that are loaded and the last column is the
modules that use that module. Are all four of these modules loaded on
