    Make sure you have the package linux-restricted-modules-generic installed. This package contains the updated firmware for that wireless card. Compiling and installing it yourself is always a tedious operation. Note: replacing the firmware for this card poses no risk since it is loaded at runtime. Once you have that package your network manager should detect available networks and allow you to configure everything without a glitch. Let me know if that solves your issues, I have delt with this card extensively.
    Hey, once you said (in your #11 post in this thread) linux-restricted-modules-generic package contains updated firmware for 3945. I have a question:

    Is not the iwl3945 an open source project? If so why would it be restricted software? Furhtermore, i have this package installed but i cannot see any 3945 restricted modules in my System>Administration>Hardware Drivers. Could you please explain it?

    Cool Re: Problem about Intel 3945 wireless card

    Hi Jasonkirk2006,

    Yes, it is an open source project. Sorry, the last time I had to mess with my ipw3945 there was a working driver in the restricted modules under Feisty Fawn which was this version available via sourceforge. Intel had kind of developed it about 95% and then left it hanging for Linux community to finish off. located here..
    http://ipw3945.sourceforge.net/

    That would be why you don't see it in restricted modules on Hardy. I suppose Intel revamped their old ipw3945 driver as the newer iwl3945 one, located here
    http://linuxwireless.org/en/users/Drivers/iwl3945

    I have not had any problems with this driver since getting the ipw3945 driver working on Feisty. I must have assumed that this driver was simply carried forward to hardy since it worked fine on Feisty Fawn. My bad.

    Re: Problem about Intel 3945 wireless card

    dvlong what is the result of running this command?
    modprobe iwl3945

    Perhaps the module iwl3945 is not being loaded...


    On another note, there are potential solutions here...

    Re: Problem about Intel 3945 wireless card

    Thanks!

    I've been through both of these threads - and have finally solved [?] for now. I've put this in a different thread on the Networking & Wirless Forum but will place it here in case it points anyone in a right direction:

    Both Pytheas22 and Chili555 have threads that many people have been helped by in this forum:

    Networking & Wireless Forum - Re: Wireless only works if Wired network is plugged in first.

    My Post...
    After 2 weeks and finally getting frustrated enough with getting nowhere, I decided to start with a clean slate.

    I reinstalled Hardy. Did all the updates.
    then ran the codes:
    1.sudo apt-get install linux-backports-modules-hardy-generic
    2.sudo su
    3.echo -e “alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1″ > /etc/modprobe.d/iwl3945
    4.reboot

    When this didn't fix anything I was beginning to get nervous.

    I then simply reset my router to the factory defaults, (this makes no sense because the wireless initially stopped working without touching the router) and made the necessary ip changes so that it doesn't conflict with my adsl modem settings, and my wireless began to work immediately.

    My wireless router is a Linksys WRT54GL.

    Now I can go back and work under the shade tree again!
