This page describe how to use iwl-wifi ([http://www.intellinuxwireless.org/ Intel Wireless WiFi Link driver]) with an iwl3945 or iwl4965.
EXPERIMENTAL : People willing to use iwl4965 with Debian/Etch should read [http://www.nanonanonano.net/linux/debian/iwlwifi]. This page use a pre-"experimental" kernel and apply to Debian/Testing or Debian/Unstable only.
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
use network-manager to use the interface !
Interfaces
Once the module is loaded, ifconfig -a should show two interfaces (wlan0 is the "main" one).
wlan0 Link encap:Ethernet HWaddr 00:13:02:4c:12:12 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) wmaster0 Link encap:UNSPEC HWaddr 00-13-02-4C-12-12-65-74-00-00-00-00-00-00-00-00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Common problems and errors
Interfaces is named "wlan0_rename" (sysfs_create_symlink failed)
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: ACPI: PCI Interrupt 0000:03:00.0[A] -> GSI 17 (level, low) -> IRQ 22 kernel: PCI: Setting latency timer of device 0000:03:00.0 to 64 kernel: iwl3945: Detected Intel PRO/Wireless 3945ABG Network Connection kernel: iwl3945: Tunable channels: 13 802.11bg, 23 802.11a channels kernel: wmaster0: Selected rate control algorithm 'iwl-3945-rs' kernel: net eth2: device_rename: sysfs_create_symlink failed (-17) 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
