How I was able to reinstall the proper WiFi driver if you experience the No WiFi Adapter is available issue in Settings>WiFi
```
sudo apt-get purge bcmwl-kernel-source
sudo apt update
sudo update-pciids
sudo apt install firmware-b43-installer
sudo reboot
```
Downloaded brcmfmac43602-pcie.txt here: https://bugzilla.kernel.org/attachment.cgi?id=285753

removed the macaddress of xx:xx:xx:xx:xx:xx and replaced it with 00:90:4c:0d:f4:3e

sudo cp brcmfmac43602-pcie.txt /lib/firmware/brcm

iwlwifi 11n_disable=1

> sudo vim /etc/modprobe.d/iwlwifi.conf
在文尾添加 
options iwlwifi 11n_disable=1

reloading the brcmfmac driver
