Comment: use ip not ifconfig

This page describe how to use iwl-wifi ([http://www.intellinuxwireless.org/ Intel Wireless WiFi Link driver]) with an iwl3945 or iwl4965.

Installation

Install kernel 2.6.23

The iwl* modules requires the new kernel's IEEE 802.11 subsystem (mac80211). both modules are available in linux-image-2.6.23 (currently in DebianUnstable).

It's assumed you know how to install it !

Loading the iwl3945 / iwl4965 modules

  • The module should be loaded automatically by udev when the system starts.

Using IwlWifi

Interfaces

Once the module is loaded, ip a should show two interfaces (wlan0 is the "main" one). 

  • 3: wmaster0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc ieee80211 qlen 1000
    link/ieee802.11 00:13:e8:70:69:fb brd ff:ff:ff:ff:ff:ff
4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:13:e8:70:69:fb brd ff:ff:ff:ff:ff:ff

Common problems and errors

Another symptom is that Network-manager don't handle the wireless card.

/var/log/syslog may show : 

kernel: iwl3945: Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 0.1.15ks
kernel: iwl3945: Copyright(c) 2003-2007 Intel Corporation

kernel: udev: renamed network interface wmaster0 to eth2
kernel: net wlan0_rename: device_rename: sysfs_create_symlink failed (-17)

  • This may occurs if you had used ipw3945 module before.

Resolution

in /etc/udev/rules.d/z25_persistent-net.rules remove the line like 

# PCI device 0x8086:0x4227 (ipw3945)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:13:02:4c:12:12", NAME="eth2"

then remove the module and re-insert it. 

rmmod iwl3945
modprobe iwl3945

in /etc/udev/rules.d/z25_persistent-net.rules you should now have a line like : 

# PCI device 0x8086:0x4227 (iwl3945)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:13:02:4c:12:12", ATTR{type}=="1", NAME="wlan0"

Identify wireless card

Running  lspci -nn  should list one of : 

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4222] (rev 02)

or 

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4227]

or 

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 4965 AG or AGN Network Connection [8086:4229]

or 

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 4965 AG or AGN Network Connection [8086:4230]
