While GS65's wifi module, Killer 1550i(which is roughly Intel 9560), doesn't supported in \~4.17 kernels, I managed to get the wifi working by compiling latest iwlwifi kernel module and including them.
But when I recover from the suspend, the wifi module is hard blocked(I could confirm this by
sudo rfkill list all).
After the hard block, the airplane mode cannot be turned off by
sudo rfkill unblock all or
sudo modprobe iwlwifi. Googling suggests to use hardware airplane mode key, which is Fn+F10 on GS65, doesn't work in all situation(before/after hard block).
It's really frustrating since whenever I suspend my laptop for battery I have to reset it. Any help will be great. Thanks in advance!
