As long as I know, on a linux system the wired devices were called eth0, eth1, eth2 etc. Wireless devices were wlan0. Since I started using ubuntu on my laptop this has changed, and not for the better. The wired devices were something like enx00938229aab8 or the like. Difficult to type (when auto-completion failed) and fairly annoying. Fortunately, there is a quite simple fix to this. Adding the following line to /etc/defaults/grub
After that, simply running grub-mkconfig and update-grub (or update-grub2, depending on which you use). Then reboot the system to apply these new settings changes all interface names back to their ‘normal’ self again.
