"java" is short for "Just Another Vulnerability Accronym".
Recently, I've encountered some WiFi issues with my beloved x230, the network card randomly not being able to be loaded/detected:

It seems to be this bug
from 2015, marked as CLOSED WILL_NOT_FIX, and fortunately, a kind soul
provided a workaround:
# lspci | grep Centrino
03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 3e)
# echo 1 > /sys/bus/pci/devices/0000\:03\:00.0/remove
# echo 1 > /sys/bus/pci/rescan
Apparently, this might be a hardware problem, meh.
