I have that device working in a fresh install of 8.04, so lets see if
you might have some old settings running that are causing trouble.

The driver for this device is supposed to be iwl3945.  A firmware
package should have been installed in support of that device.

If you open a terminal, and you type

# sudo /sbin/lsmod

it lists out loaded kernel modules. If you don't see iwl3945 in there,
it means it is failing. Could try to load manually

# sudo /sbin/modprobe iwl3945

Then run

# dmesg

to see if it started.

Here's a very important thing to know:

The LED light for the wireless device DOES NOT turn on, even if it is working!

So in the terminal again, make sure the network-manager is running

# /etc/init.d/network-manager restart

and then

# nm-applet

should make sure the network-manager applet is running.  Try to use
that to manage your connection.

IF you want the LED light to come on, you can get it by installing the
backported linux kernel module.

There is also an updated version of the Network Manager available.
Look in archives for last week for an email I posted in this list
called "Head's up for people with Wireless in Harty, especially Intel
Wireless IPW adapters".  That points at the links.
