Do you have a switch to enable/disable WiFi?
Do you dual boot the system?

my switch is enabled
and yes it is a dual boot

In Windows device manager, disable the ability of the device to wake up the system as well as disable power management.

can to tell me how to do that

Right click My Computer -> Manage
Device Manager, expand network devices, right click WiFi adapter -> properties

You'll find one of the tabs has the 2 options

Thanks actionparsnip, that solved my question.
