Fixing Intel Wireless Card 3945ABG Defination in Ubuntu 8.04 Hardy

June 9, 2008

When i First Installed Ubuntu 8.04 i was really happy , but i got shocked when i found that my intel wireless card is not working , The system appears to see it  but i cant connect nor search for networks .

After a lot of search in the ubuntu , I found that this was a formal ubuntu 8.04 Bug… Here It is

So I found a Solution Here   , I tried making it more usable , Here it is , Open up your lovely Terminal

  • sudo bash ( Just to make it more easy )
  • modprobe -r iwl3945
  • Navigate to /etc/modprobe.d   command :::  cd /etc/modprobe.d
  • Create file named iwl3945     command  :::  touch  iwl3945
  • Open The File     command : gedit iwl3945
  • Add The Following To the File
    • alias wlan0 iwl3945
    • options iwl3945 disable_hw_scan=1
  • Save The File and exit
  • modprobe iwl3945
  • sudo ifconfig wlan0 up

Now You will find networks jumping into your wireless networks list

    greaaat! 😀 (spent 5 hours trying to fix this on my dell inspiron 1520).
    where does this fabulous fix come from ?
    What do “alias wlan0 iwl3945” and “options iwl3945 disable_hw_scan=1” do actually ?
