CN3 Mobile Computer User’s Manual 105
A network connection icon
appears in the toolbar, but then
disappears.
The CN3 may not be communicating with the intended access point. Make sure
the CN3 network name matches the access point network name. Default
network name is “INTERMEC.”
Access point may not be communicating with server. Ensure the access point is
turned on, properly configured, and has 802.1x security enabled.
The CN3 indicates it is not
authenticated.
User Name and Password parameters on the CN3 must match the user name and
password on authentication server. You may need to reenter the password on
both the CN3, authentication server.
On your authentication server, the user and group are allowed and the group
policy is allowed to log into the server. For help, see the documentation that
shipped with your authentication server software.
IP address and secret key for access point must match the IP address and secret
key on authentication server. You may need to reenter the IP address and secret
key on both your access point and authentication server.
Authentication server software is running on server PC
You are setting up multiple access
points in a network, with different
SSIDs, and the connection fails.
CN3 does not save WEP key values when changing the SSID. Reenter the WEP
key value after changing the SSID, select Apply Network Settings from the
802.11 Radio menu. You should now be able to connect to the different access
points.
You receive a message saying “The
server certificate has expired or
your system date is incorrect” after
you perform a clean-boot on the
CN3.
Date and time are not saved when a clean-boot is performed. Reenter the date
and time, then select Apply Network Settings from the 802.11 Radio menu.
Problems While Scanning Bar Codes
Problem Solution
You cannot see a red beam of light
from the scanner when you press
the Scan button and aim the
scanner at a bar code label.
You may be too far away from the bar code label. Try moving closer to the bar
code label and scan it again.
You may be scanning the bar code label “straight on.” Change the scanning angle
and try again.
Move within 2 feet of a wall to test the effective scan of the scanner. For help
scanning bar codes, see page 15.
When you release the Scan button
or handle trigger, the Good Read
light does not turn off.
The Good Read light will remain on if you configure the CN3 to use
continuous/edge triggering. If you configure the CN3 for level triggering and the
Good Read light remains on, there may be a problem. Press the Scan button or
pull the trigger again without scanning a bar code label. If the light is still on,
contact your local Intermec representative.
