    Enable Maximized Compatibility

    Locate the Maximize Compatibility toggle. Ensure this is switched off unless you are connecting legacy devices, as disabling it ensures the use of stronger WPA3 encryption protocols.

    To immediately disconnect an unknown device, toggle the Allow Others to Join switch to the Off position. This terminates all active sessions instantly. Re-enable the switch when you are ready to allow authorized devices to reconnect.

    Note: Changing your password will also forcefully disconnect all currently tethered devices.
