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

printer.
Restart the wireless router or reset the network settings for the printer.
