1. Check the following two points:

   • Unplug the power to your wireless access point/router, wait for 10 seconds, and then plug it back in.
   • If your WLAN 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), the information may be incorrect.

   Reconfirm 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 access point/router is set to 2.4 GHz or 2.4 GHz/5 GHz mixed mode.
