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?
g
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.
g
If the camera’s IP address is set to
[Manual setting]
in network
environments using a DHCP server, change the setting to
[Auto
setting]
(

Also check the following points when responding to errors numbered 21–23.
o 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 ( = 482).
