connected. Press
[OK]. Another mobile device is already connected
to the Wi-Fi Direct™ network where the
Brother machine is the G/O. After the current connection between your
Brother machine and another mobile device
has shut down, try to configure the
Wi-Fi Direct™ settings again. Confirm the
connection status by printing the Network
Configuration Report (see Software and
