There is a switch or button on your computer that turns off wifi and
bluetooth, sort of an "airplane mode". Find it, and toggle it to the
other position, see if that fixes it.
As for the interface name, you can add something to your kernel
commandline in /etc/default/grub. I did this:
# GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0"
Then run: sudo update-grub
or equivalent, and on your next boot you should get your old eth0,
wlan0, etc interface names back.
