Basic Troubleshooting
If you cannot connect your USI 802.11b WLAN CF Card to the network, the
first troubleshooting hint is to verify LED activity of the CF Card . The LEDs
may show the following behavior:
•
Power LED on, Transmit/Receive LED off
•
Power LED on, Transmit/Receive LED flickering
•
Both LEDs blink once every 10 seconds
•
Power LED is Flickering
•
No LED Activity
If there is LED activity, run the Client Manager diagnostic tool on your station
to:
•
Run the Link Test to verify the quality of wireless network interface
radio communications with the network.
Power LED on, Transmit/Receive LED off
This LED status indicates normal operation:
•
The USI 802.11b CF WLAN Card is powered on
•
The Transmit/Receive LED indicates there is no activity on the wireless
network.
The absence of activity on the Wireless Network Interface might be related to
he fact that:
•
You moved out of Wireless Range of the Base Station(s) that could
provide access to the selected network.
•
There are no Wireless Client Stations in the Wireless Range of your
computer to participate in the selected Peer-to-Peer Group.
•
The Base Station(s) that could provide access to the selected network has
(have) a problem (e.g. power is off).
Power LED on, Transmit/Receive LED flickering
This LED status indicates normal operation:
•
The USI 802.11b WLAN CF Card is powered on
•
The Transmit/Receive LED indicates activity on the wireless network.
If the radio of your USI 802.11b WLAN CF Card seems to communicate with
other radio devices, but does not succeed in actually connecting to the
network (i.e. the power and radio LED shows normal activity), you may need
to verify whether your operating system installed the correct Network Protocol
Settings.
Both LEDs blink once every 10 seconds
This LED indicates that the USI 802.11b WLAN CF Card is powered on
and working properly, but it is not able to establish a wireless connection
to the wireless network.
Possible causes might be:
•
Your wireless station is outside the Wireless Range of the Base
Station(s) that could provide you access to the selected network.
•
The Wireless Network Interface of your station has been configured
with an incorrect Network Name and/or Encryption Key settings.
•
By mistake you selected a configuration profile on your wireless
station, that does not belong to the wireless network that you want
to connect to.
•
The Base Station(s) that could provide access to the selected
network has (have) been configured to deny access to stations that
use the value ANY as their Network Name.
Contact your LAN Administrator for information about the correct values of
the parameter settings that apply in your network.
No LED Activity
If there is absolutely no LED activity on the Power LED and
Receive/Transmit LED of the USI 802.11b WLAN CF Card, this may be
due to one of the following reasons:
•
The USI 802.11b WLAN CF Card device is not properly connected
to your computer.
•
No driver was installed to allow communication between your
computer and the wireless network interface.
Power LED is Flickering
A flickering Power LED identifies that you enabled the Card Power
Management option for the USI 802.11b WLAN CF Card of a Wireless
Client Station (Advanced Settings).
