Chapter 4 — Troubleshooting and Maintaining the CN3
Solution
Host may have deactivated or lost current terminal
emulation session. In a TCP/IP direct connect network,
turn off the "Keep Alive" message from host to maintain
the TCP session while the computer is suspended.
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.
There may be a problem with the host computer, with
the connection between the 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.
In a TCP/IP network, there may be a problem with the
connection between the access point and the host
computer. Check with your network administrator or see
your access point user's manual for troubleshooting
information.
Solution
Make sure the CN3 IP address, host IP address, subnet
mask, and default router are configured for your
network.
The CN3 may not be communicating with the access
point. Make sure the network name (SSID) on the CN3
matches the access point network name.
802.1x security network may not be active. Make sure the
server software is properly loaded and configured on the
server PC. See the server software documentation for
help.
