Hi John Counihan,
In reviewing our previous troubleshooting, we successfully narrowed the problem to the WPA2/WPA3-Personal handshake mechanism and correctly identified that updating the Intel AX211 driver alongside disabling MAC randomization are the foundational prerequisites. However, reevaluating the persistence of the "Some information has changed" error indicates we must address how Windows 11 natively handles WPA3 transition mode. While adjusting your Access Point's 802.11r and PMF settings is the optimal infrastructure-side fix, we must acknowledge a known Windows 11 behavior where the WLAN AutoConfig service caches invalid Master Session Keys when a network dynamically downgrades from WPA3-SAE to WPA2-PSK during AP roaming. When this key rotation fails, the OS security subsystem assumes the network Pre-Shared Key has been altered by an administrator, triggering the credential prompt loop.
To permanently resolve this client-side without altering your school's Wireless LAN Controller, you must bypass the mixed-mode negotiation entirely by hardcoding the connection protocol. First, scrub the corrupt credential cache by opening an elevated command prompt and executing rundll32.exe keymgr.dll, KRShowKeyMgr to delete any saved network passwords. Next, navigate to HKLM\SOFTWARE\Microsoft\WlanSvc\Interfaces in the Registry Editor, locate the subkey corresponding to your Intel AX211 GUID, and clear the underlying profile cache to purge the corrupted state. Finally, create a standardized WLAN XML profile where the <authentication> tag is explicitly defined as WPA2PSK rather than a mixed variant, and the <encryption> tag is set to AES. Deploy this forced-WPA2 configuration to your affected laptops using netsh wlan add profile filename="your_wpa2_profile.xml" user=all. This definitively prevents the Intel NIC from attempting the unstable WPA3 handshake on your mixed network, stabilizing the connection according to Microsoft's documented deployment practices for transition-mode network compatibility.
Hope this answer brought you some useful information. If it has, please consider accepting the answer so that other people sharing the same issue would benefit too. Thank you :)
