11: Connection target not found
In the case of [q], is Camera Connect running?
Establish a connection using Camera Connect (p.33, 84).
In the case of [l], is the power of the printer on?
Turn on the printer.
Are the camera and the access point set to use the same
encryption key for authentication?
This error occurs if the encryption keys do not match when the
authentication method for encryption is set to [Open system].
The setting is case-sensitive, so check upper- and lower-case
characters. Make sure that the correct encryption key for
authentication is entered on the camera (p.80, 119).
12: Connection target not found
Is the power of the target device and access point on?

establish the connection again.
