No wifi on HP Pavilion DV7 with Ubuntu 12,04

Question

I recently updated to 14.04 but I found a whole lot of problems and decided to revert my changes with a clean install of 12.04. I didn't have any problems with the wifi before but now I can't seem to get it online

running nmcli nm

RUNNING   STATE        WIFI-HARDWARE WIFI     WWAN-HARDWARE  WWAN
running   disconnected enabled       enabled  enabled        disabled

running vi /var/lib/NetworkManager/NetworkManager.state

[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true

running iwconfig

eth0  no wireless extensions
lo    no wireless extensions

running ifconfig only gives eth0 and lo so no wlan interface

running lspci -nnk | grep -iA2 net

Didn't work, is already the latest version.. – Noosrep Jun 28 '15 at 12:58
According to your output in the question, it is not installed. Kernel modules: bcma. – Pilot6 Jun 28 '15 at 13:01
And according to the output I received from the apt-get install it is, see updated question – Noosrep Jun 28 '15 at 13:03
In 12.04 it may be not supported. Try sudo apt-get install firmware-b43-installer. – Pilot6 Jun 28 '15 at 13:06
It aborts with following error: Unsupported device(s) found: PCI id 14e4:4727 The wifi has worked before btw with 12.04 – Noosrep Jun 28 '15 at 13:10

Following answer did the trick:

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

If it isn't installed, just proceed.

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