I cannot connect to an AP.
Q
(The wireless connection is
disconnected frequently.)
 Check the Network Key.
A Right-click the Wireless Network
Connections icon from the Taskbar
and click View available wireless
networks. If wireless networks are
found, it indicates that the device is
operating properly but the network
settings may have a problem. Please
check the Network Key (Encryption
Key) and the AP settings.
 Check if there is a device nearby
using the same frequency band.
A1 If there is a device nearby using the
same frequency band such as another
wireless LAN device, wireless video
transceiver, microwave oven, plasma
bulb, etc., channel interference
may occur. If you experience
interference from another device, it
is recommended changing the AP
channel.
A2 When operating in EEE802.11g mode,
if there is a IEEE802.11b device
operating nearby, you may experience
low data rates or even disconnection
as it operates in Hybrid mode.
 Check the authentication type.
A A connection may be disconnected
after a period of time if the "Use
IEEE 802.1x network authentication"
option is selected when IEEE 802.1x
authentication is not being used.
View the properties of the
corresponding AP in the Wireless
Network Properties. In the
Authentication tab, unselect the "Use
IEEE 802.1x authentication in this
network" option.
For detailed information on the
authentication server, ask your
network administrator.
 Check the AP settings.
A1 Check if the surroundings are
appropriate for a wireless LAN.
A wireless LAN connection may
be limited by the surrounding
environment and distance. Obstacles
such as walls and door mats affect
the quality of the wireless LAN signal.
You have to install an AP in a high,
open position far away from any other
radio signal sources.
