63: Wireless LAN authentication failed
Are the transmitter and wireless LAN terminal configured for the same
authentication method?
The transmitter supports these authentication methods: [Open system], [Shared key],
[WPA-PSK], and [WPA2-PSK] (p.19).
When using an AirPort for communication in infrastructure mode, [Open system] is not
supported. Configure a [Shared key] on the transmitter (p.19).
Are the transmitter and wireless LAN terminal configured with the same encryption
key for authentication?
The setting is case-sensitive, so check upper- and lower-case characters. Make sure the
correct encryption key for authentication is entered on the transmitter and wireless LAN
terminal (p.20).
If you are filtering by MAC address, did you register the transmitter's MAC address
on the wireless LAN terminal?
Register the transmitter's MAC address (p.80) on the wireless LAN terminal.
64: Cannot connect to wireless LAN terminal
Are the transmitter and wireless LAN terminal configured for the same encryption
method?
The transmitter supports these encryption methods: [WEP], [TKIP], and [AES] (p.19).
If you are filtering by MAC address, did you register the transmitter's MAC address
on the wireless LAN terminal?
Register the transmitter's MAC address (p.80) on the wireless LAN terminal.
65: Wireless LAN connection lost
Are any obstacles blocking the line of sight between the transmitter and the
antenna of the wireless LAN terminal?
Move the antenna to a position clearly visible from the point of view of the transmitter
(p.111).
The wireless LAN connection was lost, for some reason, and the connection
cannot be restored.
The following are possible reasons: excessive access to the wireless LAN terminal from
other terminals, a microwave oven or similar appliance in use nearby (interfering with
IEEE 802.11b/g/n reception on the 2.4 GHz band), or poor weather or high humidity
(p.111).
