Nice, now you have faster WiFi speed along with 5G speed.
With MediaTek 9500 Chipset in your new Vivo X300 Pro phone, I tend to think you can beat 4Gbps with the Archer BE805 router (MediaTek Filogic 880 chipset).
MediaTek 9400/9500 chipset WiFi 7 enabled mobile phones will be the best match with Archer BE805.
