❏ Example of connecting to SSIDs with a dierent 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 dierent 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
If the IP address assigned to the printer is 169.254.XXX.XXX, and the subnet mask is 255.255.0.0, the IP

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 Settings > Network Settings > Connection Check.
Restart the wireless router or reset the network settings for the printer.
