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.
A privacy separator on the wireless router is available.
Solutions
Most wireless routers have a privacy separator feature that blocks communication between connected
devices. If you cannot communicate between the printer and the computer or smart device even if they
are connected to the same network, disable the privacy separator 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.
Select Settings > General Settings > Network Settings > Advanced on the printer's control panel, and
then check the IP address and the subnet mask assigned to the printer.
Restart the wireless router or reset the network settings for the printer.
