Ubuntu 13.10 Dell E1705 Wired and Wireless Broken

Question

When installing from a live USB, the wired connection worked. Upon reboot the wired and wireless do not work now.

lspci shows them as:

Wired BCM4401-b0

Wirelss BCM4311 R2

How can I fix this?

"Edit" sudo modprobe b44 and the terminal cursor sits there solid. I dont see the typical command line response.

Edit: E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. ~$ sudo dpkg --configure -a Setting up bcmwl-kernel-source (6.30.223.141+bdcom-0ubuntu1) ... Removing old bcmwl-6.30.223.141+bdcom DKMS files...

Please hook up the ethernet and open a terminal and do:

sudo modprobe b44

Your ethernet should now be working and we'll use it to fix your wireless:

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

Detach the ethernet, reboot and tell us how it's working.
