I have a Dell Inspiron 1520 that is rather finicky and had Windows XP installed on it. I recently installed Ubuntu 13.04 "Raring Ringtail", and since, I haven't been able to get the WiFi to work. It has a Dell 1390 wlan mini card for WiFi. Any ideas are appreciated, I have spent hours searching this and many other forums for a solution, and haven't found any that will work.

Thanks, New Ubuntu User

Try this:

To fix your wireless problem, this is what you have to do:

Remove the default driver:

sudo apt-get remove --purge bcmwl-kernel-source

Install a the Linux Firmware nonfree drivers:

sudo apt-get install linux-firmware-nonfree

Load the b43 module:

sudo modprobe b43

To make it work automatically, do:

sudo su
# echo "b43" >> /etc/modules

Thanks for this, the first line seems to work, but once I enter the second line, it says the following: Reading Package lists... done Building dependency tree Reading state information... Done E:Unable to locate package linux-firmware-unfree (End of code) Any help would be appreciated, and thanks for trying the first time. @Mitch –  Nick J. Jul 2 '13 at 23:09
Did you the command correctly? The error message says E:Unable to locate package linux-firmware-unfree. is nonfree, and not unfree –  Mitch Jul 3 '13 at 4:33
@Mitch- Hi, I just figured that for some reason, my ethernet has stopped working, and will not start again. I have checked the connection and even tried it with another computer, which worked fine. Any suggestions on how to fix this? Thanks. –  Nick J. Jul 3 '13 at 19:52
What is the output of sudo rfkill list all? –  Mitch Jul 3 '13 at 20:16
Nothing, it just gives me another line to type in. –  Nick J. Jul 3 '13 at 20:22

I think its quite a late but for others. Got same type of issue so I used following commands

sudo apt-get --purge remove bcmwl-kernel-source
sudo apt-get install patch
sudo apt-get install bcmwl-kernel-source

13.04 is not supported anymore, please use the latest version 14.04LTS or the latest version 14.10.

Open a terminal and if you get asked for permissions write sudo before:
