In Asus laptops, you can turn on the Wi-Fi very easily with the hot keys. You would have to know how to do it. That is all.
Press the power button and turn on your Asus laptop.
Then login to your laptop.
Now, press FN + F2 keys simultaneously and then release. This can be used to toggle between turning on and turning off the Wi-Fi adapter.
You would know that the Wi-Fi is on when the adapter lights up.
