1. Check the following:
   • Make sure the wireless access point/router is powered on.
   • Move your machine to an obstruction-free area, or closer to the wireless access point/router.
   • Temporarily place your machine within about 3.3 feet (1 meter) from the wireless access point/router when you are configuring the wireless settings.
   • If your wireless access point/router is using MAC address filtering, confirm that the MAC address of the Brother machine is allowed in the filter.
2. If you manually entered the SSID and security information (SSID/authentication method/encryption method/Network Key (Password)), the information may be incorrect.
   Confirm the SSID and security information, and re-enter the correct information as necessary.
   This device does not support a 5 GHz SSID/ESSID and you must select a 2.4 GHz SSID/ESSID. Make sure the wireless access point/router is set to 2.4 GHz or 2.4 GHz/5 GHz mixed mode.

The wireless network and security setting you entered may be incorrect.

Confirm the wireless network settings.

Confirm that the entered or selected SSID/authentication method/encryption method/UserID/Userpass are correct.

The Authentication/Encryption methods used by the selected wireless access point/router are not supported by your machine.

For the infrastructure mode, change the authentication and encryption methods of the wireless access point/router. Your machine supports the following authentication methods:

• WPA-Personal
  TKIP or AES
• WPA2-Personal
  AES
• Open
  WEP or None (without encryption)
• Shared key
  WEP

If the issue is not solved, the Network Name (SSID) or network settings entered may be incorrect. Confirm the wireless network settings.

For Ad-hoc mode, change the authentication and encryption methods of your computer for the wireless setting. Your machine supports the Open authentication method only, with optional WEP encryption.

The security information (SSID/Network Key (Password)) is incorrect.

 The security information (SSID/Network Key (Password)) is incorrect.Confirm the Network Name (SSID) and the Network Key (Password).

If your router uses WEP encryption, enter the Network Key (Password) used as the first WEP key. Your Brother machine supports the use of the first WEP key only.

The wireless security information (Authentication method/ Encryption method/ Network Key) is incorrect.

Confirm the wireless security information (Authentication method/ Encryption method/ Network Key) using the Authentication Method table in error TS-04.

If your router uses WEP encryption, enter the key used as the first WEP key. Your Brother machine supports the use of the first WEP key only.

The machine cannot detect a wireless access point/router that has WPS enabled.

To configure your wireless settings using WPS, you must operate both your machine and the wireless access point/router.

if you do not know how to operate your wireless access point/router using WPS, see the documentation provided with your wireless access point/router, ask the manufacturer of your wireless access point/router, or ask your network administrator.

Two or more wireless access points that have WPS enabled are detected.

Confirm that only one wireless access point/router within range has the WPS method active and try again.
