Question about TP-Link Tl-Wa850re

The TL-WA850RE (300 Mbit/s) supports WPA3 security only on hardware version V7, as confirmed by the manufacturer's official firmware update notes. For earlier hardware versions, WPA3 is not supported, and the device will only repeat the security mode of the main router, which may limit you to WPA or WPA2 depending on your network setup. If you are unsure of your hardware version, check the label on the device or the management interface for details.
