LeBrun, Michael Franc 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. 'lsmod | grep iwl' now shows iwl3945 125016 0 mac80211 164704 1 iwl3945 lib80211 5064 1 iwl3945 cfg80211 30560 2 iwl3945,mac80211 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? now 'less /etc/sysconfig/networking/devices' only shows: drwxr-xr-x. 2 root root 4096 2009-07-27 08:42 ./ drwxr-xr-x. 4 root root 4096 2009-04-14 07:25 ../ -rw-r--r--. 1 root root 153 2009-07-27 08:47 ifcfg-eth0 -rw-r--r--. 1 root root 198 2009-07-27 08:47 ifcfg-wlan1 -rw-------. 1 root root 5 2009-07-27 08:47 keys-wlan1 And now, 'less /etc/sysconfig/network-scripts' only shows one ifcfg* file: -rw-r--r--. 1 root root 254 2009-05-01 13:35 ifcfg-lo 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. 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. 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. 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.

You can try running and debugging the bash scripts that attempt to bring up your wireless adapter, starting with /etc/sysconfig/network-scripts/ifup. 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. 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. 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. 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". 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. <div class="moz-signature">-- <title>Fate of the Peacock</title> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> Steven F.
