A device is
already

Another mobile device is already connected
to the Wi-Fi Direct network when the
Brother machine is the G/O (Group Owner). After the current connection between your
Brother machine and another mobile device
has shut down, try and configure the Wi-Fi
Direct settings again. You can confirm the
connection status by printing the Network
Configuration Report uu Network User's
Guide: Printing the Network Configuration
Report.
I cannot complete the Wi-Fi Direct network setup configuration.
Question Solution
Are your security settings
(SSID/password) correct?  Reconfirm the SSID and password.
If you are using your machine as a G/O (Group Owner) in manual configuration,
the SSID and password are displayed on the machine's control panel during the
configuration procedure.
If you are using your mobile device as a G/O (Group Owner) in manual
configuration, the SSID and password are displayed on the mobile device's
screen during the configuration procedure.
 For information on what the SSID name is, see SSID on page 21.
Is your Brother machine
placed too far from your
mobile device? Move your Brother machine within about 3.3 feet (1 meter) from the mobile device
when you configure the Wi-Fi Direct network settings.
Are there any obstructions
(walls or furniture, for
example) between your
machine and the mobile
device? Move your Brother machine to an obstruction-free area.
Is there a wireless computer,
Bluetooth supported device,
microwave oven or digital
cordless phone near the
Brother machine or the mobile
device? Move other devices away from the Brother machine or the mobile device.
I have checked and tried all of
the above, but still cannot
complete the Wi-Fi Direct
configuration. Is there
anything else I can do?  Turn your Brother machine Off and back On. Then try and configure the Wi-Fi
Direct settings again.
 If you are using your Brother machine as a client, confirm how many devices
are allowed in the current Wi-Fi Direct network and then check how many
devices are connected.
