HOW TO: Get wireless (Intel 3945ABG) working in Ubuntu 8.04 (Hardy Heron)

Problem:
The wireless card seems to be switched on but it does not not pick up any networks and is essentially useless.


Solution:

1. Open a terminal


2. Input the following:
$sudo modprobe -r iwl3945
$cd /etc/modprobe.d
$gksudo gedit iwl3945
3. In the blank file enter the following:
alias wlan0 iwl3945
iwl3945 disable_hw_scan=1
4. Save the file and close it


5. In the terminal:
$sudo modprobe iwl3945
$sudo ifconfig wlan0 up
Wait a few minutes and hotspots should start showing up.

  2. Hey there would you mind sharing which blog platform you're using? I'm looking to start my
    own blog soon but I'm having a tough time choosing between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design seems different then most blogs and I'm looking for
    something completely unique. P.S Sorry
    for being off-topic but I had to ask!
