• Information Required to Change Wireless Router Settings

Note

• If you do not understand the settings of the wireless router, inquire with the help desk or ask somebody capable of changing the settings of the wireless router to perform the work.

1. Step 1 Update the firmware of the wireless router.

   Wireless routers update their firmware frequently. If it's not the latest version, update it.

2. Step 2 Check the encryption method.

   Connecting is possible when the wireless encryption method of the wireless router is compatible with the printer.

   Check the encryption method, SSID, and encryption key of the computer/smartphone/tablet you want to connect and the currently connected wireless router. If the encryption method used is not supported by the printers, change the encryption method to one that is compatible with the Wi-Fi router and that the printers can use.

   Note

   • If you change the encryption method, redo the wireless connection.
     • Wi-Fi connection
   • If the settings of the wireless router have been changed, also reconnect the other devices connected to the same wireless router.

   In the list below, the encryption level increases in the direction of bottom to top.

   The encryption methods that can be used with printers

   

   • WPA3 or WPA3-Personal

   • WPA2-PSK/ WPA3 or WPA2-Personal/ WPA3-Personal

   • WPA2-PSK (AES)

   • WPA2-PSK or WPA2-Personal

   • WPA-PSK/ WPA2-PSK or WPA-Personal/ WPA2-Personal

   • WPA-PSK (AES)

   • WPA-PSK or WPA-Personal

   Note

   • If the encryption method of the wireless router includes WPA3, you may not be able to use WPS connection. Connect using the manual connection setting method on the printer, or change the encryption method of the wireless router.
   • The security protocol such as WPA2-PSK (AES) or WPA3-SAE (AES) is recommended to be set to wireless router for security reasons.
   • In cases where TKIP or AES are not displayed when the encryption method is WPA, WPA2, or WPA/WPA2, they can almost always both be used.

   The encryption methods that cannot be used with printers

   

   • WPA3-Enterprise

   • WPA2-Enterprise

   • WPA-Enterprise

   • WPA-PSK (TKIP) / WPA2-PSK (TKIP)

   • WPA2-PSK (TKIP)

   • WPA-PSK (TKIP)

   • WEP

   Note

   • Some models also support WPA2-Enterprise / WPA3-Enterprise.

3. Step 3 Turn off the privacy separator function.

   If the wireless router has the privacy separator function turned on, the printer cannot print even if it is connected to the wireless router. A mobile wireless router has this function turned on, so be sure to turn it off when using your printer.

4. Step 4 Turn off MAC address filtering.

   If MAC address filtering of the wireless router is turned on, add the MAC address of the printer. Or, set MAC address filtering to off.

5. Step 5 When using a mesh wireless router.

   If the SSID of 5 GHz (6 GHz) and 2.4 GHz is the same when using a mesh wireless router (including when using the band steering function), printing may not be possible even when connected to the wireless router.

   Turn off the band steering function so that there will be separate SSIDs, one for 5 GHz (6 GHz) and one for 2.4 GHz. If the same SSID is used with 5 GHz (6 GHz) and 2.4 GHz even though there is no band steering function, set different SSID.

   Then, connect both the computer and printer to the wireless router. If the problem persists, change the settings so that the computer connects to the SSID to which the printer is connected.
