Why does WPS connection fail on WPA3-Personal?
WPA3-Personal is the latest, most secure encryption option currently available for Wi-Fi devices. It works with all devices that support Wi-Fi 6 (802.11ax) and some older devices. However, WPA3 is not compatible with WPS connection. If you want to connect devices with WPS, configure WPA2-Personal on the wireless setting page of your D-Link router.
