How to fix it ?

provide output from:
mhwd-kernel -li

It appears that’s an RTW89 chipset. Iinstall rtw89-dkms-git from the AUR (Arch User Repository).

I did installed it from aur then restarted pc …no effect

Well, did it install successfully? Did you check your inxi output to see if anything changed? You can run inxi -Nxz to show Network only.

It seems the rtw89 driver is now included in the kernel as of 5.16. Try installing 5.18 and see if it works.
