Cannot connect to a Network
The problem could be one of the following issues.
Something is wrong with the network devices for Wi-Fi connection.
Solutions
Turn off the devices you want to connect to the network. Wait for about 10 seconds, and then turn on the
devices in the following order; wireless router, computer or smart device, and then printer. Move the
printer and computer or smart device closer to the wireless router to help with radio wave
communication, and then try to make network settings again.
Devices cannot receive signals from the wireless router because they are too far apart.
Solutions
After moving the computer or the smart device and the printer closer to the wireless router, turn off the
wireless router, and then turn it back on.
