The wireless feature is not ON. Check the following point and try to set up your wireless connection again:

Turn the wireless feature ON.

The wireless access point/router cannot be detected. Check the following points and try to set up your wireless connection again:

1. Turn your wireless access point/router off, wait for 10 seconds, and then turn it on again.
2. Temporarily place your machine closer to the wireless router/access point when you are configuring the wireless settings.
3. If your wireless router/access point is using MAC address filtering, confirm the MAC address of the Brother machine is allowed in the filter. You can find the MAC address by printing the Network Configuration Report.
4. If you manually entered the Network Name (SSID) and security information (authentication method / encryption method / Network Key (Password)), the information may be incorrect. Check the Network Name and security information and re-enter the correct information.
5. Your Brother machine may not support a 5 GHz SSID/ESSID. Make sure your wireless access point/router is set to 2.4 GHz or 2.4 GHz / 5 GHz mixed mode. For more information, see the documentation provided with your wireless router/access point.

Your Brother machine does not support the authentication and encryption methods used by the selected wireless router/access point.

Change the authentication and encryption methods of the wireless router/access point. Your Brother machine supports the following authentication and encryption methods:

• WPA-Personal

  TKIP / AES

• WPA2-Personal

  TKIP / AES

• Open

  WEP or None (without encryption)

• Shared key

  WEP

If your issue is not solved, the Network Name (SSID) or security settings you entered may be incorrect. Check all wireless network settings are correct for your network.

The Network Name (SSID) and Network Key (Password) are incorrect. Check the following points and try to set up your wireless connection again:

1. Confirm the Network Name (SSID) and Network Key (Password). Brother cannot provide this information. If your Network Key contains upper-case and lower-case letters, make sure you type them correctly.
2. If you cannot find the Network Name (SSID) and security information, see the documentation provided with your wireless router/access point, or contact the router manufacturer, your system administrator, or Internet service provider.
3. If your wireless router/access point uses WEP encryption with multiple WEP keys, write down and use only the first WEP key.

The wireless security information (Authentication method / Encryption method / Network Key) is incorrect. Check the following points and try to set up your wireless connection again:

1. Confirm the Network Key. If your Network Key contains upper-case and lower-case letters, make sure you type them correctly. Brother cannot provide this information.
2. Confirm whether the authentication method entered and the authentication method or encryption method supported by the wireless router/access point are the same.
3. If the network key, authentication method, and encryption method have been confirmed, restart your wireless router/access point and Brother machine.
4. If the machine is still unable to connect and your router supports WPS, try connecting with WPS. To set up your wireless connection using WPS, you must enable WPS on the Brother machine and wireless router/access point.

The machine cannot detect a wireless router/access point that has WPS enabled. Check the following points and try again:

1. To check if your wireless router/access point supports WPS, look for the WPS symbol displayed on the router/access point. For more information, see the documentation provided with your wireless router/access point.
2. To set up your wireless connection using WPS, you must configure both your Brother machine and the wireless router/access point.
3. If you do not know how to set up your wireless router/access point using WPS, see the documentation provided with your wireless router/access point, or contact the router manufacturer, your system administrator, or Internet service provider.
