What to check on the camera

Is another device on the camera network using the same IP
address as the camera?
 Change the camera’s IP address to avoid using the same address
as another device on the network. Otherwise, change the IP
address of the device that has a duplicate address.
 If the camera’s IP address is set to [ Manual setting ] in network
environments using a DHCP server, change the setting to [ Auto
setting ] (p.86, 102).
23: Device with same IP address exists on selected
network

Check also the following points when responding to errors numbered
21 - 23.
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.85, 101).
