Background
If you've been using an Intel 3945 ABG or 4965 AGN adapter in gutsy and previous releases, you have probably been using the ipw3945 driver. According to the project page, this driver is now deprecated in favor of the Intel® Wireless WiFi Link drivers for Linux, or iwlwifi driver. The full transition to the new driver will occur in the Hardy Heron release. The Debian Wiki has a wiki page for using the iwlwifi driver, and this page reflects the necessary changes that may be different for Ubuntu systems.
Migrating from ipw to iwlwifi
Delete the following 2 lines from /etc/udev/rules.d/70-persistent-net.rules :
# PCI device 0x8086:0x4222 (ipw3945) SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1b:77:19:62:9a", NAME="eth1"
Then add the following to /etc/modprobe.d/blacklist :
# disable ipw3945 old intel3945 driver blacklist ipw3945 blacklist ieee80211 blacklist ieee80211_crypt
Add the following to /etc/modules :
# new intel3945 iwlwifi driver iwlwifi_mac80211 iwl3945
After editing the above files, issue these commands at the command line :
sudo modprobe -r ipw3945 sudo modprobe -r ieee80211 sudo modprobe -r ieee80211_crypt_tkip sudo modprobe -r ieee80211_crypt_ccmp sudo modprobe -r ieee80211_crypt_wep sudo modprobe -r ieee80211_crypt sudo modprobe -r mac80211 sudo modprobe iwlwifi_mac80211 sudo modprobe iwl3945
Your wireless interface should now appear as wlan0. You should also see an interface called wmaster0. If you don't see them or you get errors when you run the modprobe commands, try rebooting. When you're able to see these two new interfaces, Network Manager should recognize the wlan0 interface and allow you to connect to your wireless network.
Common problems and errors
Interface is named "wlan0_rename"
When you issue ifconfig -a you see an interface named wlan0_rename and you don't see and interface named wmaster0. This generally means that the udev rules are not set up correctly. You may also see something like this in /var/log/syslog :
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)
Resolution
Make sure you deleted the lines from /etc/udev/rules.d/70-persistent-net.rules. If you still have problems, try adding these lines to the same file :
# PCI device 0x8086:0x4222 (iwl3945) SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1b:77:19:62:9a", ATTRS{type}=="1", NAME="wlan0"
Then run these commands :
sudo modprobe -r iwl3945 sudo modprobe iwl3945
You may also try rebooting. For other problems, please refer to the Debian Wiki page. -- Geeksmith <<DateTime(2008-02-13T23:46:08Z)>>
