Google helped me discover a secret button at the edge of my laptop. So, if I move that button to the left, I won't be able to toggle airplane mode, but if I move it to the right, I would be able to do so.

oh well, Glad you found it.!

I don't have that secret button on my laptop haha!

Lol! Glad you asked or you'd be left wondering and being frustrated. A friend and Google are helpful xD

It's frustrating because i can't connect to the internet....

So after many tries, I decided to ask a friend about it

My friend, in turn, asked Google about it.

try to shutdown and restart if that doesn't help i guess you need to check settings or install new window..
