What does error code E-2, E-3, or E-7 mean on the network connection report?

These errors indicate that no wireless network name (SSID) was found, or the entered security key or password does not match your router or access point. Try turning off your router, waiting 10 seconds, and turning it back on, and move the printer closer to the router to improve signal strength. Also confirm that your SSID uses only ASCII characters and that you are entering the correct password. (Page 43)
