A transit-yard tablet profile is set to WPA3-Personal only, but the yard AP SSID is still WPA2-Personal per the current design. Discovery works; secure connection fails. What mismatch is occurring?
Select an answer to reveal the explanation.
Short Explanation
The tablet insists on WPA3 while the AP is still WPA2-Personal—those AKMs don’t match. Either update the infrastructure per design or set the client to the approved WPA2-Personal mode. Wishful automatic fallback isn’t a troubleshooting plan.
Full Explanation
Authentication and key management (AKM) suites must be compatible between client and AP. A WPA3-only client profile will not complete security negotiation with a WPA2-Personal-only BSS. Technicians align client security type to the deployed SSID (or follow a planned migration) rather than assuming silent fallback, addressing Layer 3 addressing first, or blaming antenna polarization for AKM failure.
