My laptop is Dell Inspiron 15R. I have installed Ubuntu 12.10 a week ago, and realized that the option for wireless is not there. Not even in the network settings, so I went through the problems posted earlier and I thought its because of Broadcom. So I tried:

sudo apt-get update  
sudo apt-get install b43-fwcutter

But still the wifi is not working.

When I typed rfkill list all in the terminal I got the following output...

0: hci0: Bluetooth  
Soft blocked: yes  
Hard blocked: no  

It's showing me only bluetooth and nothing about wireless. I guess wireless is blocked somewhere.

Please help...

By typing the command :


You can check what kind of wireless card your Dell Inspiron 15R have. I guess it's probably something like bcm43xx.

If so, the answer to get your wifi working is :

sudo apt-get install linux linux-headers-generic kernel-package
sudo apt-get purge b43-fwcutter firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl*
sudo apt-get install b43-fwcutter firmware-b43-lpphy-installer bcmwl*

Reboot !

You can also try a sudo rfkill unblock all it helped me once with my inspiron 15R.
