The SecureEasySetup™ is an easy way to configure your Brother device to your wireless network settings. By pushing a button on the wireless router or access point, you can send the wireless network and security settings to the printer. Your router or access point must also support SecureEasySetup™. See the user's guide for your wireless LAN router or access point for instructions on how to use the SecureEasySetup™ feature of that device.
