Hey guys I almost have my wifi up. I have everything installed however when I go to run the ipw3945d command I get the following:

ipw3945d - regulatory daemon
Copyright (C) 2005-2006 Intel Corporation. All rights reserved.
version: 1.7.22
2007-07-07 20:08:37: ERROR: Could not find Intel PRO/Wireless 3945ABG Network Connection

Any ideas? I really need to get this working so any help would be great.
Thank you,
nomb

Here's how I got it working:

First, uninstall all other traces of the ipw3945 driver. Make sure non-free is enabled in your /etc/apt/sources.list

Next, run this command:

Code:

aptitude install ipw3945d ipw3945-source firmware-ipw3945 module-assistant

Then,

Code:

m-a prepare

Code:

m-a a-i ipw3945

Code:

modprobe ipw3945

Now the driver should be working. Run iwconfig -a to find out what device the wireless device is. If it was eth2 for example, run:

Code:

dhclient eth2

Replace eth2 with the device name.

Sorry...

This is what I did:

Make sure you install the ipw3945 modules and firmware first. (search for “ipw3945″ in synaptic)
# aptitude install module-assistant
# module-assistant update
# module-assistant prepare
# module-assistant auto-install ipw3945
# modprobe ipw3945

I got the same problem and i tried the solutions here and none work for me, dmesg finds it but with a error

--
ipw3945: Intel(R) PRO/Wireless 3945 Network Connection driver for Linux, 1.2.1dmpr
ipw3945: Copyright(c) 2003-2006 Intel Corporation

ipw3945: Could not read microcode: -2
--
iwconfig finds nothing, neither ifconfig either but when i installed ubuntu 7.04 before debian then it found it, so there is drivers for it that is working but i can't get it to work on debian not sure why!

i have tried both methods posted above but no luck, the only thing i'm not sure of is "uninstall all other traces of the ipw3945 driver" i did a "aptitude remove ipw3945d ipw3945-source firmware-ipw3945" then installed it again!

any ideas
