iwl3945 / ipw3945 problem

Yes, I've already searched the forums many of times and tried everything within those posts. I still have no idea what I'm doing wrong here. First, I'm running Arch-current on my HP nc2400 laptop that uses the Intel Pro Wireless 3945 chipset. I've installed BOTH the iwlwifi and ipw3945 packages and still haven't had any luck.

r00@myhost ~]$ lspci
8:00.0 Network controller : Intel Corporation PRO/Wirelss 3945ABG Network Connection (rev 02)

If I use the ipw3945 package with the deamon I receive:

r00@myhost ~]$ipw3945d
ipw3945 - regulatory daemon
Copyright (C) 2005-2006 Intel Corporation. All rights reserved.
version 1.7.22
2007-10-28 10:21:31 ERROR: Could not find Intel PRO/Wireless 3945ABG Network Connection

Add either one of these to /etc/rc.conf MODULES section won't load them either. When the system boots, it will just throw a "Module not found".

I've installed:

iwlwifi / ipw3945 with ucode's
wireless_tools
wpa_supplicant

Is there something I'm missing here?

Re: iwl3945 / ipw3945 problem

I have the same wireless card in my laptop (toshiba) and it is working fine.
A few things to check,
Is there a physical switch on your laptop that you can turn the wireless card on and off with? Sometimes when I put my laptop in a bag it gets switched off and when I boot I cant find my wireless card. I dont know of a graceful way to turn it back on while the system is running (I try to turn it on but nothing changes) so I shut down, turn it on and power back on.

I have the following installed for it:
iwlwifi-3945-ucode 2.14.1.5-1
ipw3945d 1.7.22-3
iwlwifi 1.1.0-3

I dont have to load any module in my rc.conf, here are the important parts:

#
HOSTNAME="myhost"
#
#
lo="lo 127.0.0.1"
eth0="dhcp"
wlan0="dhcp"
INTERFACES=(lo !eth0 !wlan0)
#
gateway="default gw 192.168.1.1"
ROUTES=(!gateway)
#
#NET_PROFILES=(main)
.
.
.
DAEMONS=(network)

I just bring the interfaces up manually.
What do you get with 'ifconfig -a'?


The Internet...? Is that thing still around?

Re: iwl3945 / ipw3945 problem

There is a physical switch that is indeed on, the bright blue light indicates this.

ifconfig -a just brings up eth0 and lo. There is no wlan0 anywhere. I don't think it's picking up the module.

Re: iwl3945 / ipw3945 problem

Did you do 'modprobe ipw3945' before trying to start the daemon? http://wiki.archlinux.org/index.php/Ipw3945
# modprobe ipw3945
# ipw3945d

Re: iwl3945 / ipw3945 problem

I've went over that many of times.

#modprobe ipw3945
FATAL: Module ipw3945 not found.

I don't get it...

Re: iwl3945 / ipw3945 problem

Try removing the ipw3945 and ipw3945-ucode (pacman -Rns ipw3945 ipw3945-ucode)
And installing iwlwifi and iwlwifi-3945-ucode

Then modprobe iwl3945

Re: iwl3945 / ipw3945 problem

Yeah, I finally decided to remove all the packages and starting over by JUST installing iwlwifi and iwlwifi-3945-ucode and now the module loads.

Thanks a lot DeltaXFX!

Re: iwl3945 / ipw3945 problem

Im having a problem with this, none of the combinations seem to work, why was the old ipw3945 replaced?

Re: iwl3945 / ipw3945 problem

ipw3945 was proprietary and required a daemon as well as the kernel module. iwlwifi is Intel's open source suite of wireless drivers and they only require the kernel driver.

Re: iwl3945 / ipw3945 problem

Hrmm... well, assuming you've read the wiki, followed the instructions, and uninstalled the ipw3945 drivers:

What are you using to manage your wireless?  Basic network scripts? Network Manager?
What does your rc.conf look like? Specifically, your modules and daemons array and network settings...
What type of wifi network are you trying to connect to?  WEP or WPA? Is the SSID hidden?

Re: iwl3945 / ipw3945 problem

Netowk scripts to connect to a netwrok, working scripts with ipw3945 deamon that no longer works.
Rc.conf i can post when im back home, deamons is (alsa,hal, and other default ones) and the module iwl3945 is been loaded upon boot.
WEP netwrok, no SSID is not hidden.

EDIT: After reading the wiki I saw the note "these drivers are currently experimental and may not work with all chipsets" It reccomended using the ndiswrapper, but Im just using the old method of ipw3945d, but now having to load a module and have the deamon load before the network deamon (this is new steps you have to take for anyone wanting to use same method as me).
