Notes on Wi-Fi Connection

• Make sure your computer and the wireless router (A) are connected. For details on checking these settings, see the manual supplied with the wireless router or contact its manufacturer.

  
• Configuration, router functions, setup procedures and security settings of wireless routers vary depending on the system environment. For details, see the manual for your wireless router or contact its manufacturer.
• Depending on your country or region, this printer does not support wireless networking standards using the 5 GHz band.
• If the current channel bandwidth setting on your device does not include 20 MHz, TKIP cannot be used for a security protocol. Change the setting to something that includes 20 MHz. For improved security, we recommend that you set to AES together with WPA2 or higher security.
  The connection between your device and the wireless router will be temporarily disabled while the setting is changed. Do not proceed to the next screen of this guide until setup is complete.
• When connecting to Wi-Fi outdoors, do not connect to a 5 GHz network (SSID).
  The 5 GHz band available for use with the printer includes the channels that are allowed for indoor use only, depending on your country or region.
  For details on the 5 GHz network (SSID) of your wireless router, see the manual supplied with the wireless router, or contact its manufacturer.
• For office use, especially when connecting with IEEE802.1X/EAP (WPA/WPA2/WPA3 Enterprise), consult your network administrator.
• Note that if you connect to a network with no security protection, your personal information could be disclosed to a third party.
• You cannot use the printer over Wi-Fi and wired connections at the same time. Wi-Fi and USB can be used at the same time.
