2. Check 3 Check the wireless router's security protocol settings.

   To set the wireless router's security protocol to TKIP, change the channel bandwidth setting to something that includes 20 MHz, and then redo the printer's Wi-Fi settings. For improved security, we recommend that you set to AES together with WPA2 or higher security.

   If the security protocol is set to TKIP, you cannot use IEEE802.11n (maximum channel bandwidth: 40 MHz) or IEEE802.11ac (maximum channel bandwidth: 80 MHz) as the communication standard.

   The wireless router's network name (SSID) is normally described on the wireless router; for details on the security protocol settings, see the manual supplied with the wireless router or contact its manufacturer.

3. Check 4 Check the wireless router's settings.

   If the wireless router's DHCP function is off or MAC address filtering is enabled, you need to change the wireless router's settings. After changing, redo the printer's Wi-Fi settings.

   For details on checking or changing the wireless router settings, see the wireless router manual or contact its manufacturer.
