Was having some wifi connectivity issues and tried this driver /
solution that triggered the crash:

sudo apt-get install build-essential linux-headers-generic dkms git
git clone https://github.com/Mange/rtl8192eu-linux-driver.git
sudo dkms add ./rtl8192eu-linux-driver
sudo dkms install rtl8192eu/1.0
