Set up your Brother machine on a wireless network (Windows/macOS)

For certain models, the wireless network connection can be used only when the optional Wireless Module is installed.

1. Before you set up your Brother machine

You must find out the wireless network settings of your wireless router or access point. Check and write down the current wireless network settings below (you will need this information later):

Network Name (also known as "SSID" or "ESSID")
Network Key (also known as "Password", "Security Key", or "Encryption Key")

How to find the Network Name (SSID) and Network Key (Password)

Check the base or side of your wireless router or access point.
See the documentation provided with your wireless router or access point.

If you need assistance during setup and want to contact Brother customer service, make sure you have your SSID (Network Name) and Network Key ready. We need this Information to assist you, so please get ready them.
If you do not know this information (SSID and Network Key), you cannot continue the wireless setup.
If you cannot find your wireless Network Name and Network Key, contact your Internet service provider or router manufacturer.

If you cannot find the Network Name (SSID) and Network Key (Password) of your wireless router or access point, see the following FAQs:

For Macintosh users

> Click here to see to find the wireless security information for Macintosh.

After checking the network information of your wireless router or access point, go to step 2 to set up your machine on a wireless network.

If your wireless router or access point uses WEP encryption with multiple WEP keys, write down and use only the first WEP key.

2. Set up a Brother machine on a wireless network

To set up your Brother machine on a wireless network:

Connect the power cord to your Brother machine and then connect it to an AC power outlet (electrical socket).
Turn your Brother machine on.
Press (Settings) > All Settings > Network > WLAN (Wi-Fi) > Find Wi-Fi Network.

If your machine displays the All Settings menu on the Home screen, skip the Settings menu.
When Enable WLAN? or Switch Network interface to wireless? appears, press Yes.
This will start the wireless setup wizard.
The machine will search for your network and display a list of available Network Names (SSIDs).
If a list of SSIDs displayed, press the Up or Down arrow to select the SSID you wrote down earlier.
Press OK.
Do one of the following:
- If you are using an authentication and encryption method that requires the Network Key (Password)
  Enter the Network Key, then press OK to apply your settings.
- If your authentication method is Open System and your encryption mode is None
  Go to the next step.
The machine attempts to connect to the wireless device you have selected.
- If your Brother machine connected successfully
  The machine's LCD displays Connected.
- If the connection failed
  The machine will print a wireless connection report. Check the error code on the printed report.
