Description
This means the Airborne Device Server cannot locate a
wireless network that matches the module
configuration. For a association to occur both the SSID
and security settings must match exactly the settings
on the target Access Point or Wireless Router. Please
refer to the Enterprise Command Line Interface manual
for information on how to configure the module.
This means the Airborne Device Server cannot locate a
wireless network that matches the module
configuration. It is possible that the target network is
not in range, this may be due to the location of the
Evaluation board or that the target network AP or WR
are not powered. Confirm availability of wireless
network.
The system failed POST. It is recommended the
evaluation board is RESTARTED by pressing SW2 or
using SW1 to power the board down and up.
Make sure the Device Server Module (Ref Figure 1) is
attached to the Evaluation board. Confirm the module
is seated correctly by pushing lightly down on the units
using the edges of the device. Avoid pushing on the
label.

This means the module is failing to
associate/authenticate with the a wireless network that
matches the installed SSID. The cause of this is
incorrect configuration of the security settings; please
refer to the Enterprise Command Line Interface manual
for details.
If WPA2-Enterprise is being used please confirm that
the Certificates and Private Keys have been installed
on the Device Server and that the correct file names
are being used for authentication.
If DHCP is being used this indicates a failure in the
DHCP service, this can be caused by there being no
DHCP server on the network. Confirm there is a DHCP
server available for the module to lease an IP address
from.
If a static IP address is being used this indicates either
an illegal IP address has been stored on the device or
an incomplete network configuration has been
provided.
Please refer to the Enterprise Command Line Interface
manual for details on installing a valid WLN_CFG
configuration.
