Iwlwifi doesn't works with Intel 3945!!

I have this Wireless network card:

# lspci | grep Wirel
06:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

and followed the guide on http://en.gentoo-wiki.com/wiki/Iwlwifi .
But I still not see any wlan device when typing ifconfig or iwconfig!

Ok ; your curent running kernel does not have a iwl3945.ko module, but your current /usr/src/linux kernel source tree states that you actually did compile a kernel with support for iwl3945 (your wifi network adaptater). Did you forget to reboot after building the kernel ?

Please also post the output of :

Code: Select all

$ uname -a
$ ls -alh /lib/modules/
$ find /lib/modules/ -iname iwl*.ko

On another subject : next time you build a custom kernel, you may select CONFIG_IKCONFIG_PROC.

│ Location:
│ -> General setup
│ -> Kernel .config support (IKCONFIG [=y])

After compiling your kernel, you will need to install the firmware too :

Code: Select all

# emerge -av iwl3945-ucode

And yes, I have also emerge the ucode thing. Maybe I need to re-emerge network tools then because I emerged it before the ucode and installed the modules.
It can also have something to do with the switch that turn on/off the wlan, now it was on whole the time and maybe it should be off before everything is installed.

But it stands on the wiki that the things should be build as modules (m).

Post by **cach0rr0** » Sat Dec 26, 2009 7:06 pm

and the wiki is correct - keep it as a module

So the fact that modprobe doesn't find it, but it exists at

Code: Select all

/usr/src/linux-2.6.30-gentoo-r8/drivers/net/wireless/iwlwifi/iwl3945.ko

would strongly hint at the notion that you need to cd into /usr/src/linux and type "make modules_install"

then:

Code: Select all

modprobe -v iwl3945

and show is the output

if for some reason after doing that, the assuming you've already merged the ucode, then try loading the module by hand with:

Code: Select all

insmod /usr/src/linux-2.6.30-gentoo-r8/drivers/net/wireless/iwlwifi/iwl3945.ko

and post back if it errors out with what you saw.

THANK YOU! That actually do the trick!

Now I have the wlan0 driver in the list when typing ifconfig or iwconfig and everything seems to works.
I haven't manged to connect on boot yet and get errors that some commands doesn't exist! Here is my /etc/conf.d/net file:

Code: Select all

no idea, i never configure wireless by hand

I always use wicd, which makes things much easier - if you have X working and all that, should check it out, and avoid the pain of having to configure things like wpa_supplicant.conf by hand

Post by **d2_racing** » Sat Dec 26, 2009 9:14 pm

In fact, you should use WICD, because wpa_supplicant is hard to configure the first time.

But, for the record, can you post this :

Code: Select all

# ifconfig -a
# iwconfig
# iwlist scan

Zeerak · Post by **Zeerak** » Sun Dec 27, 2009 11:47 am

Hmm I use wpa-supplicant, and it was hard to do the first time, but more so because the explanation in the handbook was hard to understand (for me) and it seemed to leave out some things that are relevant.

However, here's my wpa_supplicant.conf and /etc/conf.d/net

conf.d/net:

Code: Select all

 This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
modules=( "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"
preferred_aps=("ESSID1" "ESSID2")
essid_wlan0="any"

and wpa_supplicant.conf:

Code: Select all

# The below line mustn't be changed, otherwise the wireless won't work
ctrl_interface=/var/run/wpa_supplicant
# Allowing users to acces the WPA config
ctrl_interface_group=wheel
# Letting wpa_supplicant scan and select AccessPoint (AP)
ap_scan=1

# Network Specific information:

# Home - Aalborg
network={
  ssid="Foobar1"
  key_mgmt=WPA-PSK
  psk="XXXXXXXXXXXXX"
  priority=5
}

# Home - Copenhagen
network={
  ssid="Foo"
  key_mgmt=WPA-PSK
  psk="XXXXXXXXXXX"
  priority=2
}

# Uni - Basis
network={
  ssid="bar"
  key_mgmt=NONE
  priority=4
}

# Train: Aarhus - Copenhagen
network={
  ssid="TDC"
  key_mgmt=NONE
  priority=1
}

and her's a site to help configure: http://manual.sidux.com/en/internet-con ... wpa-en.htm

I used WICD for a while (before configuring wpa_supplicant mind you) but I found that it ran rather unstable and would disconnect me from accesspoints (amongst these my home network that has three computers on it and can support 40) and reconnect me randomly, I'm pretty sure I'm the only one/one of the few, but I decided it was easier just to remove WICD and configure wpa_supplicant. And I haven't experienced anything remotely kin to an error since.

I rather like to use network tools (iwconfig) than wpa-supplicant because I have no encryption.
