Make Intel PRO/Wireless 3945ABG work for Ubuntu 8.04

After installing Ubuntu 8.04 on my T60, I was supprised that wifi network card does not work at all.

After searching and googling I found next: In the kernel 2.6.24 driver for Intel PRO/Wireless Card 3945ABG was replaced from ipw3945 to iwl3945, and because of some bugs it does not work by default.

Google has a lot of suggestions about this issue, and after two days probing each of them, workable solution was found. Workaround is :

1. sudo modprobe -r iwl3945

2. sudo modprobe iwl3945

3. create a file named iwl3945 in /etc/modprobe.d/

3. in the file type the following and save:
    alias wlan0 iwl3945
    options iwl3945 disable_hw_scan=1
    sudo ifconfig wlan0 up

reboot Enjoy your wireless connection
