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.
