Hi @Benjiboy322
Please read my sticky on this subject in the relevant board, plus currently, the only router that supports WPA3 is the eero:-
https://community.talktalk.co.uk/t5/Fibre/Privacy-warning-this-network-is-blocking-encrypted-DNS-tra...
Further on from this, about WPA 3 specifically:-
The WPA3 security mode is a negotiated parameter when a Wi-Fi adapter is associating with an AP. They will agree on the highest security mode that they both support. This is crucial as the AP might support this mode, but a Wi-Fi adapter might only support WPA2 Personal. In that case, the connection will be secured using WPA2 Personal, not WPA3 Personal.
If the WPA3 implementation used by that AP was WPA3 Only, then the previously mentioned Wi-Fi adapter would not be able to associate with that AP at all.
WPA2 Personal has had two main enhancements added to it that are part of WPA3. These are:-
1. The KRAK vulnerability has been patched.
2. 802.11w was ratified back in 2019 and introduces Management Frame Protection (MFP).
This will require changes to the firmware of clients and access points. Alternatively, it might be available as a software-only upgrade to many types of hardware. This is also called Protected Management Frames (PMF).
Therefore, some APs and adapters that support WPA2 Personal are protected & others are not. This is a negotiated parameter on device connection, requiring them both to support 802.11w. Obviously, WPA3 mandates that MFP be supported on all APs & STAs that support WPA3. 802.11w should be implemented now on any device that supports 802.11ac.
