I have problem. My Q80T would not connect to wifi router unless it is downgraded from WPA3 to WPA2 and PMF (protect management frames) is disabled. As a router i am using FritzBox 7590. I am suspecting that there might be bug in router firmware not allowing TV to connect. For that reason i would like to know if there was anyone successful connecting QLED 2020 series TV to wifi where there is WPA3 and PMF enabled.
