To dual boot with Windows the following change is recommended
Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Uncheck Turn on fast startup
I have an Intel 9260 WiFi card and had to do the following
(Not sure if the iwlwifi.conf change is necessary, but the grub change definitely is)
sudo nano /etc/modprobe.d/iwlwifi.conf
Add the following
options iwlwifi enable_ini=0
options iwlwifi power_save=0
options iwlmvm power_scheme=1
sudo update-initramfs -u
sudo nano /etc/default/grub
Modify the line starting with GRUB_CMDLINE_LINUX_DEFAULT to the following
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_port_pm=off"
sudo update-grub
Reboot
