Intel 3945 Wireless Help - FC5

Hi All,

I've read all the threads on this board (and in a lot of other places) and I'm soooo close having my 3945 working on my Dell Inspiron 9400 running FC5. Here's where I'm at:

I have installed the ieee80211 framework
I have installed the Intel ipw3945 drivers from the Intel site
I have dep'modded the ipw3945 module, and put the proper line in
my module.conf.local (might not have that name quite right) to
load it at boot
A dmesg | grep ipw shows that card is detected by proper name and
A ps aux | grep ipw shows the daemon (ipw3945d) is running

Ifconfig shows only the lo interface
Iwconfig shows l0, eth0 and sit0 but 'no wireless extensions'
beside all of them.

FC's network configuration GUI (neat) won't show me the card when
I try to create a new wireless interface (likely because it's not
aware that it's a wireless card).

SoI think I'm close, but the problem seems to be that while the
card seems to load at boot, FC can't see it.

Anyone have any ideas?

Use lsmod to determine if the kernel module is loaded. If it is, try rebooting. Is it being loaded automatically?

Make sure that wireless-tools and wpa_supplicant packages are installed.
Use the /usr/sbin/iwconfig command. Does the wireless device show up?
If so, try the "/usr/sbin/iwlist <devicename> scan" command. If you see a list of Access Points, then the hardware is working and the kernel module is working.

Fedora Core, SuSE, and I believe Mandriva have a directory tha contains system configuration information. The network configuration GUI dialog is a front end for editing config files. Nearly all of the information you set go into a file somewhere in /etc/sysconfig/ named ifcfg-<interface name>.

On my system it is /etc/sysconfig/network/ifcfg-wlan0.
On your system, these config scripts may be in /etc/sysconfig/network-scripts/ instead. There may be a "man 5 ifcfg" man page. Also check for documentation in /usr/share/doc/initscripts-*/sysconfig.txt
You could manually produce your own ifcfg-<interface> config script based on this information. The device may subsequently show up in your network device gui configuration dialog.
