When operating in EEE802.11g mode, if there is a IEEE802.11b device operat-
ing nearby, you may experience low data rates or even disconnection as it oper-
ates 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 adminis-
trator.
•
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. Obsta-
cles 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. If the AP is excessively far away, or is installed at the end of a
building and you are attempting to use the wireless LAN from the other end, you
may not be able to use the wireless communication normally because the signal
is blocked by obstacles between you and the AP (such as a wall).
A2
Check if the AP operates properly. If the AP is not operating properly, turn it off
and on again and try again.
A3
Check if the AP firmware is the latest version. (For more information on the AP
firmware, ask the AP manufacturer or your product provider.)
A4
Check if the AP is properly connected to the network. Connect the LAN cable
from the AP to a computer and check if the network is connected properly.
A5
Check the Network Key (Encryption Key) settings again.
If the automatic password converting function (passphrase function) is enabled
and the wireless connection is normal but you cannot send data over the connec-
tion, please enter the Network Key (Encryption Key) manually.
A6
Check the AP settings as follows.
If there are multiple APs running at the same time, check the channel setting of
each AP. If the interval between the channels of the APs is narrow, you may ex-
perience electromagnetic interference. Set the channel numbers of the APs so that
the internals between the channels are maximized. (E.g., Ch1, Ch5, Ch9, Ch13)
