My printer won't connect to the wireless network — what should I check?

First, verify that no network (Ethernet) cable is connected, as the printer cannot connect to a wireless network when a wired cable is plugged in. Also confirm that the printer is within 30 meters (100 feet) of the wireless access point, that the printer and computer are on the same wireless network, and that the wireless switch is turned on. If issues persist, try restarting the wireless router. (Page 3)
