63: Wireless LAN authentication failed
Are the camera and the access point set to use the same
authentication method?
The camera supports the following authentication methods: [Open
system], [Shared key], [WPA-PSK], and [WPA2-PSK] (p.68, 116).
When using an AirPort for communication in infrastructure mode,
[Open system] is not supported. Configure a [Shared key] on the
camera (p.68, 116).
Are the camera and the access point set to use the same
encryption key for authentication?
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 and the access point
(p.69, 117).
If filtering by MAC address is effective, is the MAC address of
the camera used registered at the access point?
Register the MAC address at the camera used at the access point. The
MAC address can be checked on the [General sett.] screen (p.149).
64: Cannot connect to wireless LAN terminal
Are the camera and the access point set to use the same
encryption method?
The camera supports the following encryption methods: [WEP],
[TKIP], and [AES] (p.68, 116).
If filtering by MAC address is effective, is the MAC address of
the camera used registered at the access point?
Register the MAC address of the camera used at the access point. The
MAC address can be checked on the [General sett.] screen (p.149).
65: Wireless LAN connection lost
Are any obstacles blocking the line of sight between the
camera and the antenna of the access point?
Move the antenna of the access point to a position clearly visible
from the point of view of the camera (p.164).
