Fix: Wireless

Fixing no wireless extensions

The network device is BCM4331 which means it needs the b43-firmware that can be installed via yay -s. When running iwconfig and getting the no wireless extensions response, the quickest fix was found in this question. After installing the firmware, run the following commands:

sudo rmmod wl
sudo modprobe b43
sudo modprobe -rv b43
sudo modprobe -v b43

Reboot. Test the iwconfig again.

Note: maybe download b43-fwcutter too, when I was trying to get 5GHz working, I noticed that when using only b43-firmware, iwconfig would not list the wifi. I also tried b43-firmware-dkms and it did not work because of some kernel header incompatibility/missing module tree.
