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 1.8 s and then off for 1.8 s.
9.2
Check connected status
The Kvaser Wireless Configuration program should display “Connected”. If not,
you may have an authorization problem. Check the WLAN passphrase, 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.
