Overview 1
Wi-Fi Direct™ is one of the wireless configuration methods developed by the Wi-Fi Alliance®. It allows you to
configure a secured wireless network between your Brother machine and a mobile device, such as an
®
Android™ device, Windows
Direct supports wireless network configuration using the one push or PIN Method of WPS (Wi-Fi Protected
Setup™). You can also configure a wireless network by manually setting an SSID and password. Your
Brother machine's Wi-Fi Direct feature supports WPA2™ security with AES encryption.
Phone device, iPhone, iPod touch or iPad, without using an access point. Wi-Fi

2 Your Brother machine
• Although the Brother machine can be used in both a wired and wireless network, only one connection
method can be used at a time. However, a wireless network connection and Wi-Fi Direct connection, or a
wired network connection and Wi-Fi Direct connection can be used at the same time.
• The Wi-Fi Direct supported device can become a Group Owner (G/O). When configuring the Wi-Fi Direct
network, the Group Owner (G/O) serves as an access point. See Group Owner (G/O) on page 20.
• When your Brother machine is the Group Owner (G/O), your Brother machine supports one to one wireless
communication using Wi-Fi Direct.
• Ad-hoc mode and Wi-Fi Direct cannot be used at the same time. Disable one function to enable the other.
If you want to use Wi-Fi Direct while you are using Ad-hoc mode, set Network I/F to Wired LAN or disable
Ad-hoc mode and connect your Brother machine to the access point.

device?
Is there a wireless computer,
Bluetooth supported device,
microwave oven or digital
cordless phone near 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?
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.
Move your Brother machine within about 3.3 feet (1 meter) from the mobile device
when you configure the Wi-Fi Direct network settings.
Move your Brother machine to an obstruction-free area.
Move other devices away from the Brother machine or the mobile device.
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.

Wi-Fi Direct network terms 4
Group Owner (G/O) 4
If you set Group Owner to On, your Brother machine serves as an access point when you configure a Wi-Fi
Direct network. The G/O assigns an SSID name, password and IP address for the Wi-Fi Direct network. The
default setting is Off.
Device Information 4
Device Name 4
You can check the device name of the machine in the Wi-Fi Direct network environment. The device name
will be shown as **HL-xxxx, **MFC-xxxx or **DCP-xxxx (where xxxx is your model name and ** is the
character string assigned by your Brother machine).
SSID 4
This field displays the current Wi-Fi Direct network SSID name. The display shows up to 32 characters of the
SSID name.
IP Address 4
This field displays the current IP address of the machine assigned by the G/O.
Status Information 4
Status 4
This field displays the current Wi-Fi Direct network status. When your machine is a G/O, it displays the
message G/O Active(**) (where ** is the number of devices). When your machine is a client, the machine
displays the message Client Active. If you see Off, your machine's Wi-Fi Direct interface is disabled.
Signal
This field displays the current Wi-Fi Direct network signal strength.
Channel (For HL-3140CW, HL-3150CDW and HL-3170CDW) 4
This field displays the current Wi-Fi Direct network channel.

Speed (For HL-3140CW, HL-3150CDW and HL-3170CDW)
This field displays the current Wi-Fi Direct network speed.

I/F Enable 4
If you want to use the Wi-Fi Direct network connection, set I/F Enable to On.
Network terms and concepts 4
Network terms 4
WPA2-PSK
Enables a Wi-Fi Protected Access™ Pre-shared key (WPA-PSK/WPA2-PSK), which enables the Brother
wireless machine to associate with access points using TKIP for WPA-PSK or AES for WPA-PSK and
WPA2-PSK (WPA-Personal).
AES
Advanced Encryption Standard (AES) provides stronger data protection by using a symmetric-key
encryption.
WPA2 with AES
Uses a Pre-Shared Key (PSK) that is 8 or more characters in length, up to a maximum of 63 characters.
SSID
Each wireless network has its own unique network name and it is technically referred to as the Service Set
Identification (SSID). The SSID is a 32-byte or less value and is assigned to the access point. The wireless
network devices you want to associate to the wireless network should match the access point. The access
point and wireless network devices regularly send wireless packets (referred to as beacons) which have
the SSID information. When your wireless network device receives a beacon, you can identify wireless
networks that are close enough to connect to.
