FortiAP wifi 6 very low speed

[Tutek]

Hi,

I don't know why but I have very low speeds when connecting windows 11 clients with Intel Wi-Fi 6 AX201 160Mhz cards to FortiAP 231F. I'm connected to AP using 802.11ax but can't get speeds faster that 287 Mb/s. Even when I move close to the AP I'm standing two meters away from it, this is max speed what I get. Something is wrong configured, please tell me?

Can you share the mac address of your test client and run this command while it is connected?
