Michael Frank, thanks for telling me about the 'system ->
administration -> add/remove' applet. I loaded my Intel Corporation
PRO/Wireless 3945ABG device driver with that applet.<br>
<br>
'lsmod | grep iwl' now shows<br>
iwl3945 125016 0 <br>
mac80211 164704 1 iwl3945<br>
lib80211 5064 1 iwl3945<br>
cfg80211 30560 2 iwl3945,mac80211<br>
<br>
Steven, I must have removed my wlan0 entry from NetworkManager by
mistake. Only wlan1 shows in that applet at the moment. Before I used
NetworkManger so many times. trying by experimentation, to activate my
wireless card, wlan0 showed up in NetworkManger. Is there any way for
me to get wlan0 back?<br>
<br>
now 'less /etc/sysconfig/networking/devices' only shows:<br>
drwxr-xr-x. 2 root root 4096 2009-07-27 08:42 ./<br>
drwxr-xr-x. 4 root root 4096 2009-04-14 07:25 ../<br>
-rw-r--r--. 1 root root 153 2009-07-27 08:47 ifcfg-eth0<br>
-rw-r--r--. 1 root root 198 2009-07-27 08:47 ifcfg-wlan1<br>
-rw-------. 1 root root 5 2009-07-27 08:47 keys-wlan1<br>
<br>
And now, 'less /etc/sysconfig/network-scripts' only shows one ifcfg*
file:<br>
-rw-r--r--. 1 root root 254 2009-05-01 13:35 ifcfg-lo<br>
<br>
In the NetworkManager, under the 'Devices' tab, when I click on the
'Edit' icon, the dialog page/General tab that appears, the checkbox
item for wlan1 "Controlled by NetworkManager" was definitely deselected.<br>
<br>
But then, When I try to actviate wlan1 in NetWorkManager, I always get
an error message box, saying wlan1 cannot be activated. The dialog
message box never says why wlan1 cannot be selected.<br>
<br>
I want to thank everyone for helping me so much with my problems,
trying to activate my wireless card. I know you put a lot of valuable
time in to preparing your answers to my problems. <br>
<br>
But I have to admit, I am getting sort of desperate! What should I do
next? I definitely want to access my city's WiFi network. I am going
to study the fedora-network-manager list next, even if I do not hear
from you guys. <br>

Hi Derek,<br>
<br>
There is something else that you can try but it is tedious. You can
try running and debugging the bash scripts that attempt to bring up
your wireless adapter, starting with
/etc/sysconfig/network-scripts/ifup.<br>
<br>
What I did was make copies of the scripts involved; ifup, ifup-eth,
ifup-wireless and network-functions. Step one was to make sure that
your personal copies call your personal copies (ifup --> ifup-eth
--> ifup-wireless). Step two was to place many echo statements into
your personal copies to track variable values and execution path. Step
three was to run your personal scripts.<br>
<br>
There is a Step zero, run the original scripts (I believe you start
with "ifup wlan1") to make sure that they fail to start your wireless
adapter. If the scripts do not fail, there is no reason to try to
debug them.<br>
<br>
If I had a bash debugger that would have allowed me to step through the
scripts, I would have used that. Instead, I had to do the primitive
way of adding "print" statements, in this case, echo statements. I
also did not add all the echo statements to start with. I added echo
statements first to track down which script was failing, and then added
more as needed to see what variables settings were. The first phase
was to make sure that there was an echo statement at the beginning of
every script so that I knew what script was executing when the
activation of the wireless failed. Echo statements to see what
arguments were passed to different function/script/program calls helped
too.<br>
<br>
Hopefully, this will tell you what is going wrong and provide enough
information to fix it. One of the problems that I ran into was that
the key was being provided preceded by "s:" when it should have been
"0x".<br>
<br>
Good luck. Let me know if this helps. I will try to remember what
else I did to get my wireless adapter working back in Fedora 9.<br>
