Example of connecting to SSIDs with a different frequency range
Connect the computer or smart device to the same SSID as the printer.
❏
Check the SSID that the printer is connected to by printing out the network connection check report.
❏
On all of the computers and smart devices you want to connect to the printer, check the name of the
Wi-Fi or network you are connected to.
❏
If the printer and your computer or smart device are connected to different networks, reconnect the
device to the SSID that the printer is connected to.
A privacy separator on the wireless router is available.
Solutions
Most wireless routers have a separator function that blocks communication between devices within the
same SSID. If you cannot communicate between the printer and the computer or smart device even if
they are connected to the same network, disable the separator function on the wireless router. See the
manual provided with the wireless router for details.
The IP address is incorrectly assigned.
Solutions

address may not be assigned correctly.
Print the network connection report, and then check the IP address and the subnet mask assigned to the
printer. To print a network connection report, select
