I’m experiencing a WiFi compatibility issue with my Odido Zyxel T-56 router (fiber) and a Samsung UE43TU7020 (2020) TV. The TV does not connect to the router’s WiFi network, while it connects immediately to a mobile hotspot, confirming the TV hardware is functioning properly. I have already disabled WPA3 (using WPA2-PSK only), disabled IPv6, tested 2.4GHz and 5GHz separately, manually selected channels, rebooted the router, and reset the TV network settings.
Other devices connect without any issues.
