Chapter 5 — Troubleshooting and Maintaining the CK31
Problems While Configuring 802.1x Security (continued)
Problem
A network connection icon appears in
the status bar, but it disappears.
The CK31 indicates that it is not
authenticated.
You are setting up multiple access
points in a network, with different
SSIDs, and the connection fails.
You receive a message saying "The
server certificate has expired or your
system date is incorrect" after you cold
boot the CK31.

Solution
The CK31 may not be communicating with the access point
that you want it to communicate with. Make sure that the
network name on the CK31 is the same as the network name of
the access point that you are trying to communicate with. The
default network name is "INTERMEC."
The access point that you are trying to communicate with may
not be communicating with the server. Make sure your access
point is turned on, properly configured, and has 802.1x security
enabled.
Make sure that:
• The User Name and Password parameters on your CK31
match the user name and password on your authentication
server. You may need to re-enter the password on both your
CK31 and the authentication server.
• On your authentication server, the user and group are
allowed and the group policy is allowed to log in to the
server. For help, see the documentation that shipped with
your authentication server software.
• The IP address and secret key for your access point must
match the IP address and secret key on your authentication
server. You may need to re-enter the IP address and secret
key on both your access point and authentication server.
• Your authentication server is active and that it can
communicate with your access point. You can use the PING
utility to determine communications. Go to Start >
Programs > Intermec Diagnostics > System >
Ping Utility.
• The authentication server software is running on the server
PC.
The CK31 does not save WEP key values when you change the
SSID. Re-enter the WEP key value after you change the SSID
and save your changes. You should now be able to connect to
the different access points.
The date and time on the CK31 are not saved through a cold
boot. You need to re-enter the date and time and then save your
changes.
