What to check on the camera

Do the camera and another device connected via Wi-Fi to the
same network have the same IP address?

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.121).
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 password for
authentication?

This error occurs if the passwords 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 password for authentication is set on the camera
(p.120).
