Responding to Error Messages
Are any obstacles blocking the line of sight between the
transmitter 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 transmitter (p.136).
The wireless LAN connection was lost, for some reason, and
the connection cannot be restored.
The following are possible reasons: excessive access to the
access point from other terminals, a microwave oven or similar
appliance in use nearby (interfering with IEEE 802.11n/g/b (2.4
GHz band)), or influence of rain or high humidity (p.136).
Are the transmitter 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 transmitter and the access point
(p.32).
Note that if the authentication method is [Open system], an Error
41 (“Cannot connect to FTP server”) is displayed.
