Solving Problems
The SSIDs connected from the computer or smart device and computer are different.
Solutions
When you are using multiple wireless routers at the same time or the wireless router has multiple SSIDs
and devices are connected to different SSIDs, you cannot connect to the wireless router.
Connect the computer or smart device to the same SSID as the printer.
❏ Example of connecting to different SSIDs
❏ Example of connecting to SSIDs with a different frequency range
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
address may not be assigned correctly.
