Unifi AC Pro Speedtest 5G

How fast is the 5 GHz Unifi AC Pro ? My device : 1. Gigabit Passive PoE 48V (Black) original Ubiquiti. 2. Gateway Ruijie EG209GS. 3. Laptop with gigabit ethernet LAN (1Gbps) with Software OpenSpeedtest Server. 4. Smartphone Xiaomi 11T (OpenSpeedtest Client via Chrome browser). The Unifi AC Pro using channel width 80 MHz (866Mbps) and latest firmware 2024 (6.6.77.15402) The speed seems a bit lower than Unifi AC Lite, maybe the firmware is not compatible (?)
