WiFi/Bluetooth module that is natively supported [India]

Hi, I am new here so sorry if I am breaking any rules or not following any guidelines.

I am from India and I have installed MacOS Big Sur on my Asus R542UQ. The WiFi chipset is not natively supported and I have tried many kexts but no luck so far. I looked into some natively supported WiFi chipsets but all of them are very expensive here (like $80 to $120). If you are from India and have any suggestions then please help me out.

Thanks!
