Ehternet and Wifi Not working on Ubuntu 14.04

Hi,

I recently updated my Ubuntu to 14.04. The wifi and ehternet stopped working. I am currently using the internet through a personal hotspot I created via usb. It would be great if my wifi started working again. I tried a bunch of things I read in forums and none of them worked. I am confused as what to do now.

I did the following:

Code:

sudo apt-get update
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

This is the output of

Code:

lspci -nnk | grep -iA2 net
lsmod
rfkill list all

Code:
