Broadcom BCM4311 Wireless not recognized in USB Live install of 13.10 on Dell 6400 Laptop

Hardware: Dell Laptop 6400 1.66 GHz and 2GB RAM

USB Live created with a 4 GB persistent file.

Upon startup I get a functional Ethernet WIRED connection and Bluetooth but no indications of a wireless service.

There is no hardware switch for the wireless as on some laptops. The soft switch (Fn+F2) toggles the Bluetooth on and off but the wireless indicator never lights up.

When probing around, this is what I find:

**rfkill list** //is it being killed?  No, wireless not even listed  
0: hci0: Bluetooth  
        Soft blocked: no   
        Hard blocked: no  

**iwconfig** // look specifically at the parameters of the wireless network  
    lo        no wireless extensions.  
    eth0      no wireless extensions.  

**ifconfig** // look at interface configurations

Do you have any ideas on how to get this working?

I have searched the previous questions and have tried several of the answers offered -- but no joy. It looks like these cards have been a problem for almost every release of Ubuntu and it seems that with every release there is a different twist that must be used to get it to work.

With a working ethernet connection, please do:

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

I know you said you removed it, but let's be doubly certain. Then do:

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43 && sudo modprobe b43

You should be all set.

It's working! Thank you for your help. Here is what I did: sudo apt-get install linux-firmware-nonfree returned an error: Unable to locate package linux-firmware-nonfree. After checking, I discovered that linux-firmware-nonfree is not part of the saucy repository. I edited /etc/apt/sources.list to include: deb http://us.archive.ununtu.com/ubuntu/ raring multiverse Then did sudo apt-get update then did sudo apt-get install linux-firmware-nonfree power down reboot Success –  Mark Cain Jul 3 '13 at 12:10
