Wi-Fi 7 mandates WPA3, and the required compatibility mode limits non-RSNO clients to Wi-Fi 6 operation
↗
Wi-Fi 7 mandates WPA3 on the 6 GHz band, and the WPA3-Personal Compatibility Mode workaround designed to maintain legacy connections limits clients without RSNO support to Wi-Fi 6 operation.
Deploying Wi-Fi 7 access points can break connectivity for legacy devices that misinterpret WPA3 transition mode security options. Even devices with Wi-Fi 7 hardware will be restricted to Wi-Fi 6 operation if they lack support for the Robust Security Network Override elements required by the new compatibility mode.

Wi-Fi 7 requires WPA3 on the 6 GHz band, eliminating the previous fallback of configuring access points to use WPA2 only.
The WPA3-Personal Transition Mode intended to support legacy clients causes connection failures for devices that misinterpret unrecognized security options.
The WPA3-Personal Compatibility Mode uses Robust Security Network Override elements, but clients lacking RSNO support are limited to Wi-Fi 6 operation even if they have Wi-Fi 7 hardware.
