I'm running Ubuntu 18.04 LTS on an MSI GS65 Stealth 8RE. When the laptop gets out of sleep mode, air plane mode is on and Linux says it must be deactivated via a physical switch. The FN+F10 combination to turn it off works on Windows, but doesn't on Ubuntu.
When I reboot, everything seems to be fine. So it's not too bad, but systematic and very annoying nonetheless.
I have the usual rfkill output :
ubuntu@ubuntu:~$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
