Set up your Brother machine on a wireless network.

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")

SSID

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.

Brother cannot provide this information. 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 Windows users

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.

  Make sure your access point is on, and verify your Network Settings collected in Step1.
  Temporarily move your machine as close as possible to the access point or router. Try starting from Step 2-2 again.
The machine will automatically acquire the correct TCP/IP address information from your access point/router if DHCP is enabled (DHCP is normally enabled as default for most access point routers).

Once the Brother machine is joined to the network and has a valid IP address, the wireless setup is complete.
