Connect via wireless router
• Make sure your device and the wireless router are connected. For details on checking these settings,
see the manual supplied with the wireless router or contact its manufacturer.
As for a device already connected to the printer without using a wireless router, reconnect it via a
wireless router.
• 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.

When you connect a device and the printer using Wireless Direct, the connection information will
be saved to Wi-Fi settings. The device may be connected to the printer automatically even after
disconnecting it or connecting it to another wireless router.
