English Solve setup problems Step 3. Restart components of the wireless network Turn off the router and the printer, and then turn them back on in this order: router first and then the printer. If you still are unable to connect, turn off the router, printer, and your computer, and then turn them back on in this order: router first, then the printer, and then the computer. Sometimes, turning off the power and then turning it back on recovers from a network communication issue. Step 4. Run the Wireless Network Test For wireless networking issues, run the Wireless Network Test. For more information, see "Step 2: Test the wireless connection" on page 9. Tip: If the Wireless Network Test indicates the signal is weak, try moving the printer closer to the wireless router. Step 5. Make sure your computer is not connected to your network over a Virtual Private Network (VPN) A Virtual Private Network (VPN) is a computer network that uses the Internet to provide a remote, secure connection to an organization's network. However, most VPN services do not allow you to access local devices (like your printer) on your local network while your computer is connected to the VPN. To connect to the printer, disconnect from the VPN. Tip: To use the printer while connected to the VPN, you can connect the printer to your computer with a USB cable. The printer uses its USB and network connections at the same time. For more information, contact your network administrator or the person who set up the wireless network. Reducing interference The following tips might help reduce the chances for interference in a wireless network: • Keep the wireless devices away from large metal objects, such as filing cabinets, and other electromagnetic devices, such as microwaves and cordless telephones, as these objects can disrupt radio signals. • Keep the wireless devices away from large masonry structures and other building structures as these objects can absorb radio waves and lower signal strength. • Position the access point or wireless router in a central location in line of sight with the wireless devices on the network. • Keep all wireless devices on the network within range of one another. 12
