Creating a static WLAN interface number for a wifi wireless adaptor using udev rules

If you need your USB wifi adaptor to be a certain number on boot, i.e wlan5

Using udev rules this is possible.  reference:

Run a ifconfig and get the mac address of the adaptor:
HWaddr de:ad:be:ef:ca:fe

Create a new udev rule

sudo touch /etc/udev/rules.d/70-persistent-net.rules
sudo nano /etc/udev/rules.d/70-persistent-net.rules

Insert the following lines into the file.

# Comment for the device, the following below should be on one line!
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="de:ad:be:ef:ca:fe", ATTR{type}=="1", NAME="wlan5"
