Public bug reported:

After having the PC, A Dell XPS 15 suspend and hit deep sleep I then re-
open the lid the morning after and every time after this use case it
will fail to re-connect to WiFI, some times it does not even show any
networks available.

Only way to get the machine back on the WiFI network is to reboot.
