Chapter 4 — Troubleshooting and Maintaining the CN4
CN4 Mobile Computer User’s Manual 91
The CN4 is connected to the network
and you move to a new site to collect
data. Your CN4 now shows you are not
connected to the network. Move closer to an access point or to a different location
to reestablish communications until you reconnect with
the network. Any data collected while out of range is
transmitted over the network.
The CN4 appears to be connected to
the network, but you cannot establish a
terminal emulation session 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 administrator to make sure the host is running
and allowing users to login to the system.
The CN4 appears to be connected to
the network, but the host computer is
not receiving any information from the
CN4. 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.
Problems While Configuring 802.1x Security
Problem Solution
The CN4 indicates that it is
authenticated, but it does not
communicate with the host. Make sure the CN4 IP address, host IP address, subnet
mask, default router are configured for network.
The CN4 does not appear to be
authenticating and a network
connection icon does not appear on the
toolbar. The CN4 may not be communicating with the access
point. Make sure the CN4 network name matches the
access point network name (SSID).
802.1x security network may not be active. Make sure the
server software is properly loaded and configured on the
server PC. See server software documentation for help.
A network connection icon appears in
the toolbar, but then disappears. The CN4 may not be communicating with the intended
access point. Make sure the CN4 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
You are setting up multiple access
points in a network, with different
SSIDs, and the connection fails. The CN4 does not save WEP key values when changing
the SSID. Reenter the WEP key value after changing the
SSID and save your changes. You should now be able to
connect to the different access points.
