CS40 Mobile Computer User’s Manual
Troubleshooting Your Mobile Computer
Use the troubleshooting tables in this section to fix problems with the
Bluetooth connection, Wi-Fi connection, the phone, the imager, the
camera, or general problems with operating the mobile computer.
If you send the mobile computer in for service, it is your responsibility
to save the computer data and configuration. Intermec is responsible
only for ensuring that the hardware matches the original
configuration when repairing or replacing the computer.
Troubleshooting the Wi-Fi Connection
Use this troubleshooting table to help solve problems with your
802.11 radio connection.
Problems With the Wi-Fi Connection
Problem
Solution
When you turn on the computer
after it was suspended for a while
(10 to 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 “Keep Alive” message from host to maintain the TCP
session while the computer is suspended.
The mobile computer is connected
to the network and you move to a
new site to collect data. Your mobile
computer 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 mobile computer 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 the network
administrator to make sure the host is running and allowing
users to login to the system.
The mobile computer appears to be
connected to the network, but the
host computer is not receiving any
information from the mobile
computer.
There may be a problem with the connection between the
access point and the host computer. Check with the network
administrator or use your access point user’s manual.
