Problems While Configuring 802.1x Security
If you have trouble configuring the computer for 802.1x security, check
these problems and possible solutions.
Problems with Wireless Connectivity
Problem Solution
When you turn on the CN3 after
it was suspended for a while (10-
15 minutes or longer), it can no
longer send or receive messages
over the network.
Host may have deactivated or lost current terminal emulation session. In a
TCP/IP direct connect network, turn off the “KeepAlive” message from host to
maintain the TCP session while a CN3 is suspended.
The No Network Connection
icon appears on the toolbar. The
CN3 is not communicating with
the access point.
The CN3 is not connected to access point. Ensure access point is turned on and
operating. Move closer to access point to reestablish communications. Ensure the
CN3 is configured correctly for network. CN3 radio parameters must match all
access point values.
If you have an 802.11b/g radio and its radio initialization process failed, reset the
CN3 (see page 5).
If No Network Connection icon still appears, you may have a defective radio
card. For help, contact your local Intermec representative.
The CN3 is connected to the
Intermec Application Server or
host computer and you move to a
new site to collect data. The Net-
work Connection icon was visi-
ble, but is now replaced with the
No Network Connection icon.
Move closer to an access point or to a different location to reestablish communi-
cations until the Network Connection icon appears. Any data you collected
while out of range is transmitted over the network.
The Network Connection icon is
in the toolbar, but you cannot
establish a terminal emulation ses-
sion with the host computer.
There may be a problem with the host computer, with the connection between
the Intermec Application Server and the host computer, or with the connection
between the access point and the host computer. Check with network adminis-
trator to make sure the host is running and allowing users to login to the system.
The Network Connection icon is
in the toolbar, but the host com-
puter is not receiving any data
from the CN3.
In a UDP Plus network, there may be a problem with the connection between
the Intermec Application Server and the host computer. Check with network
administrator or see the user’s manual for the Intermec Application Server.
In a TCP/IP network, there may be a problem with the connection between the
access point and the host computer. Check with network administrator or use
your access point user’s manual.
Problem Solution
The CN3 indicates that it is
authenticated, but it does not
communicate with the host.
Make sure the CN3 IP address, host IP address, subnet mask, default router are
configured for network.
The CN3 does not appear to be
authenticating and a network
connection icon does not appear
on the toolbar.
The CN3 may not be communicating with access point. Make sure the CN3
network name matches access point network name (SSID).
802.1x security network may not be active. Ensure the server software is properly
loaded and configured on server PC. See server software documentation for help.
