Windows 10: Brightness FN keys not working

Hello, yesterday i reinstalled windows 10 in my Acer Nitro 5 an515-54 laptop, and it was all working except the fn + rignt and left arrow keys. I checked in an "test your input" site, and appearently, it doesn't even register. I already tried fiddling with bios function key settings, reinstalling keyboard drivers, and even downloading other drivers.

New laptop FN keys not working [Solved]

The FN key seems to be a toggle , I don't need to press it every time I want to adjust the volume or brightness.
With all my previous laptops I needed to press the FN key WITH the f key I needed to use, so it works slightly different on this laptop than what I'm used to.

 

Brightness and Fn keys

Greetings,

On a previous computer, if I wanted to decrease brightness, I would press the F7 key. If I wanted to search, I would press Fn+F3. On my present computer, I have to use Fn+F7 to decrease brightness, and F3 alone searches. How do I reverse the Fn key requirement
to not needing it for changing brightness, sound, etc?
