Find the Wireless Security Information (e.g. SSID, Network key etc.) for Mac OS X 10.10.5 or greater

These steps may help you locate your wireless security settings if your macOS is also connected to your network using a wireless connection. If your macOS is connected to the network with an Ethernet cable, or you are unable to access the Keychain Access application, you will need to contact your router manufacturer or network admin to determine your wireless network's security settings.

  • 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.
    How can I find this information?
    • Check the documentation provided with your wireless access point/router.
    • The initial SSID could be the manufacturer's name or the model name.
    • If you do not know the security information, please consult the router manufacturer, your system administrator, or your Internet provider.
