Dell Inspiron Wifi off

Question

I installed a fresh install of Ubuntu 12.10 and this is my first Ubuntu install. I have a Dell Inspiron 6400 and my wifi is turned off and cant seem to switch it on. I searched a lot on it but can only find answers for Ubuntu 12.04 :( can someone help me please? Thanks in advance

Solution 1

I have the same problem and this was printed:

lo        no wireless extensions.

eth0      no wireless extensions.

The main problem was that I didn't check the "Install third party stuff" when my Ubuntu was installing. So I ran the following command:

sudo software-properties-gtk

Went to Additional Drivers tab and checked to use any proprietary driver I want.

Solution 2

I had the same issue and this is what worked for me:

sudo apt-get remove bcmwl-kernel-source
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
