To Steven F. 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. Derek Starr
