What should I do if the wireless network connection is not working?

Verify that no network cable is connected, as the printer cannot connect to a wireless network when an Ethernet cable is plugged in. Ensure the printer is within 30 meters (100 feet) of the wireless router, and that both the printer and router are powered on with the wireless switch enabled. Also confirm the printer and computer are connected to the same wireless network, and try restarting the wireless router. (Page 11)
