Recently my hard drive crashed and I had to reinstall windows 10. After installing Windows 10, everytime when I log in, I had to manually start the wifi. This was nagging me so I decided to fix it.
This can not be fixed by controlling startup enable applications menu.
To fix this issue to go “Device Management” (Windows+x) –> Network Adapter–> Properties
I have dell wifi adapter, you might have different depending on manufacturer of laptop.
In Properties go to Power Management and uncheck “Allow the computer to turn off this device to save power”
Now restart laptop and see wifi adapter is on
