If like me you have hardware detection issues when installing, you may end up with undesired device names. My internal card has always been wlan0, and its annoying now having it wlan1.
This is easily fixed by editing /etc/udev/rules.d/70-persistent-net.rules. As it says in the txt, change only the "NAME=" key.
Apologies if this is too simple to warrant a how-to.
