What does error code E-2, E-3, or E-7 mean on the network connection report, and how do I fix it?

These error codes mean no wireless network names (SSID) were found, or the entered security key/password does not match the router. Try turning off the router or access point, waiting about 10 seconds, and turning it on again, then move the product closer to the router and remove any obstacles. Also confirm that the SSID and password are correct, and that the SSID uses only ASCII characters and symbols. (Page 39)
