I have a Dell XPS 13 9343 Laptop onto which I have installed Linux alongside the Windows 8.1 OS it came with. This worked fine first time but last night after I caused a Kernel Panic I decided to reinstall knowing how easy and quick it was.
God was I wrong, now the Wifi will not work and I can't seem to fix it. According to 'lshw' this is the current status of the adapter AFTER installing the proprietary drivers from the System Setting GUI.

I seem to be solving my own problems after posting a lot these days. Though I am not sure exactly what I did that fixed it, here is everything I did as reference.
sudo rfkill unblock all
and other commands associated with this (google is full of them) eg: Installing Broadcom Wireless Driversgksu gedit /etc/NetworkManager/NetworkManager.conf
and changing a value from false to truesudo service network-manager restart
These last 2 steps were what I was missing but I'm not sure what else I did that contributed.
