I have a Toshiba Satellite L500 with Ubuntu 12.04 and its wifi suddenly stopped working!! I've never seen like that before.. I tried also using external USB wifis but no success. I am not able to turn it on with the function keys nor using rfkill commands and similar WLAN manipulator Commands in the terminal! It was working before for at least 4-5 months!! The computer says it's turned off by hardware. I checked it and the Driver is fine. So why can i not use any Wifi on my computer?? Why it is suddenly disabled? I checked the BIOS too there is enabled the WLAN. I spent 10 hours for searching for solutions but i am out of ideas!!! Please Help!

UPDATE: I have no wifi since i installed the following updates:

  • bind9-host
  • dnsutils
  • libdns81
  • libisccc80
  • liblwres80
  • libbind9-80
  • libisccfg82
  • libisc83
  • freeglut3 (i think this one can be ignored)

If i try to downgrade this updates in Synaptic, it wants to delete some packages like: gnome-nettool, ubuntu-desktop etc.

Here is the fix of the same issue I was facing a few months back on a Toshiba Satellite L510 laptop with Ubuntu 11.04. I hope this helps.

You can try to do so by following below mentioned steps: (1) Please try to install 'ndisgtk' (to use windows driver on ubuntu)

sudo apt-get install ndiswrapper-common sudo apt-get install ndiswrapper-utils-1.9

(2) Download relevant Realtek wireless driver (

(3) Install/Browse Realtek Drivers by opening ndiswrapper/windows wireless driver app & confirm it shows 'Hardware Present=Yes"

(4) Run following commands in terminal:

ndiswrapper -l ndiswrapper -m ifconfig wlan0 up ifconfig

Now try to connect with wireless from network manager/wicd UI.

I can't install this Driver because my system already has one and it is "working" This is not a driver issue i guess. Maybe BIOS.... – Benjamin Piller Sep 21 '12 at 11:24
