Here was some topics about wi-fi upgrade for ASUS G750. So just for everybody who interested I have upgrade my ASUS G750JX with PCI-E MPE-AX3000H (12$ on aliexpress) wi-fi 6E+bloototh 5.2 and everything working perfectly without any issues. Wireless speed even beeter comparing with my second laptop ASUS G752VY. Both laptops working with ASUS RT-AX88U router.
