Create a file for wlan0 to get its ip

/etc/network/interfaces.d/wlan0

allow-hotplug wlan0
iface wlan0 inet dhcp
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Other Notes

make
sudo make install
sudo insmod 8192eu.ko
modinfo 8192eu.ko

you need to block the previous driver rtl8xxxu with this command

echo "blacklist rtl8xxxu" | sudo tee /etc/modprobe.d/rtl8xxxu.conf;

And force RTL8192EU Driver to be active from boot:

echo -e "8192eu\n\nloop" | sudo tee /etc/modules;

Newer versions of Ubuntu has weird plugging/replugging issue (Check #94). This includes weird idling issues, To fix this:

echo "options 8192eu rtw_power_mgnt=0 rtw_enusbss=0" | sudo tee /etc/modprobe.d/8192eu.conf;

I aslo did this but it said that the build was identical as the make install output thus not overridding.

sudo dkms add .
$ sudo dkms install rtl8192eu/1.0

sudo wpa_passphrase  <SSID> <WIFI_PASSWORD> >> /etc/wpa_supplicant/wpa_supplicant.conf

In order to have a unique USB WIFI ID, raspbian assigns a string like ifconfig that can be found two ways

Replace <wlan0> with the proper UUID in /etc/network/interfaces.d/wlan0

auto <wlan0>
allow-hotplug <wlan0>
iface <wlan0> inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
