9 Troubleshooting
This section describes what to check if the connection does not work as expected.
9.1 Check the LEDs
The PWR LED (green) should be illuminated.
The WLAN LED (blue):
LED flashes about once per second (0.8 s period to be exact). Something went wrong
during start up. Try disconnecting the CAN and USB connectors and then
reconnecting.
LED gives a steady blue light when connected to the Network Enumerator Service via
a network with good signal strength.
LED gives a slow steady blink (on for about 1.8 s, than off for about 1.8 s) when
disconnected from the Network Enumerator Service, but connected to a network with
good signal strength.
If the signal strength of the network is poor, the steady part of the WLAN LED signal
described in the two cases above will start to blink. The frequency of the blinking will increase
as the network connection gets worse. For example, if you have a connection to the Network
Enumerator Service like above, but with poor signal quality, you will see a continuously
pulsating LED. If you get disconnected from the Network Enumerator Service, the WLAN LED
blinking will consist of fast blinking for 1.8s and then off for 1.8s.
9.2 Check connected status
The Kvaser Wireless Configuration program should display “Connected”. If not, you may have
an authorization problem. Check the WLAN pass phrase, security keys, encryption, and
authorization mode.
9.3 Check Signal Strength
The Kvaser Wireless Configuration program should indicate a signal strength between (circa)
-70 dBm and -30 dBm.
9.4 Check WLAN security settings
If the
Connection status
is something other than
Connected
in the parameter setter, check:
WLAN encryption and/or authorization modes must agree with the settings in the
WLAN access point. Most corporate networks are probably using WPA or WPA2.
The key is pre-shared and must be the same in the access point and in the BlackBird.
Check that you have typed in the key or pass phrase correctly. The pass phrase is
case sensitive.
Check the WLAN encryption and authorization mode with your network administrator. You
can also use the Browse networks button in the parameter setter, select the network in
question from the list, and see some technical details for that network in the pane to the right.
