Bug Description
Yesterday I got upgrades including kernel 4.15.0-39, this morning when I booted my laptop I was unable to connect or see any wifi networks, under closer inspection the whole wireless networking UI was disabled.
lshw was not showing my wireless adapter.
Rebooted with 4.15.0-38 and now everything works correctly.
lshw shows
