❏
A wireless router that is compliant with both IEEE802.11a and IEEE802.11g has SSIDs of 2.4 GHz and 5 GHz. If
you connect the computer or smart device to a 5 GHz SSID, you cannot connect to the printer because the
printer only supports communication over 2.4 GHz. Connect the computer or smart device to the same SSID as
the printer.
❏
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.

Connection
If the maximum number of devices have already been connected, you cannot connect any more devices. See the
following and try to re-connect.
Check how many devices are connected
Check how many devices are connected to the printer. If the number of connected devices has not exceeded the
maximum, a connection error may have occurred. Move the printer and computer or smart device closer to the
wireless router to help with radio wave communication, check that the SSID and password are correct, and then
try to make network settings again.
