What should I do if I see error code E-2 on my network connection report?
Error E-2, E-3, or E-7 means no wireless network names (SSID) were found. Check that your router or access point is turned on and correctly connected, move your product closer to the router, remove obstacles between them, confirm the SSID is using only ASCII characters, and verify you are using the correct wireless password.
