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 indicate that no wireless network name (SSID) was found, or the entered security key/password does not match the router or access point. To resolve this, make sure your router is turned on, move your product closer to the router, and confirm the SSID and password are correct — noting that the SSID must use only ASCII characters and symbols. You can also try turning the router off, waiting 10 seconds, and turning it back on. (Page 46)
