Chapter5 Troubleshooting Unable to Connect to the Network Problem with Wireless LAN Network Device(s) Turn off the power of all devices connected to the network. Wait about 10 seconds, then turn on the wireless router (access point), computer or smart device, and printer, in that order. Move the devices closer to the wireless router (access point) so that they can receive radio waves more easily, and reconfigure the settings. The Devices and the Wireless Router are Too Far Apart to Receive Signals Move the computer or smart device and printer closer to the wireless router, and then turn the router back on.
Wireless LAN Settings do Not Match with a Replaced New Router Reconfigure the settings to match the new router. Computer or Smart Device and Printer are Connected to Different SSIDs If you are using multiple wireless routers or a single wireless router that can use multiple SSIDs, you cannot connect a computer or smart device to a printer if the computer or smart device and the printer are connected to different SSIDs. Connect the computer or smart device to the same SSID as the printer. • Check the SSID to which the printer is connected by printing a network connection check report.
• Check the name of the Wi-Fi or network you are connected to on all computers and smart devices you want to connect to the printer. • If the printer and computer or smart device are connected to different networks, reconnect the computer or smart device to the same SSID as the printer. Privacy Separator Function of the Wireless LAN Router is Enabled Many wireless LAN routers (access points) and mobile routers have a privacy separator function that blocks communication between devices. If you cannot communicate between the printer and your computer or smart device even though they are connected to the same SSID, disable the privacy separator function on your wireless router (access point).
For details, refer to the manual of your wireless router (access point). 328
