Recently purchased to connect to 5 GHz. Result: Wi-Fi is everywhere in a 3-room apartment. Somewhere better, somewhere a little worse, but overall the result is satisfactory. In the same room with the device, the speed is definitely higher than if the connection was 2.4 GHz. There were no problems with setting up, there is an instruction in 2022, but you can do without it (the firmware is also in 2022).
