Problems With Wireless Connectivity

Problem
When you turn on the CK31
after it was suspended for 10-15
minutes or longer, it can no
longer send or receive messages
over the network.
The network connection icon is
in the status bar, but the host
computer is not receiving any
data from the CK31.
The no network connection
icon ( ) appears on the status
bar. The CK31 is not
communicating with the access
point.
The CK31 is connected to the
Intermec Application Server or
host computer and you move to
a new site to collect data. The
network connection icon was
visible but now the no network
connection icon ( ) is visible.

Chapter 5 — Troubleshooting and Maintaining the CK31
Solution
The host may have deactivated or lost your current
terminal emulation session. In a TCP/IP direct connect
network, you need to turn off the "Keep Alive" message
(if possible) from the host so that the TCP session is
maintained while a CK31 is suspended.
In a UDP Plus network, there may be a problem with
the connection between the Intermec Application
Server and the host computer. Check with your
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 your network administrator or
use your access point user's manual.
The CK31 is not connected to the access point.
•
Make sure the access point is turned on and
operating. You may also be using the CK31 out of
range of an access point. Try moving closer to an
access point to re-establish communications.
Make sure the CK31 is configured correctly for your
•
network. The radio parameters on the CK31 must
match the values set for all access points the CK31
may communicate with. For help, see "Configuring
802.11b/g Radio Communications" on page 43.
If you have an 802.11b radio, the radio initialization
•
process may have failed. Try resetting the CK31. See
"Booting the CK31" on page 123.
If you have tried these possible solutions and the no
•
network connection icon still appears, you may have
a defective radio card. For help, contact your local
Intermec service representative.
You may have gone out of range of an access point. Try
moving closer to an access point or to a different
location to re-establish communications. Once you are
in range again, the network connection icon appears
again. Any data you collected while out of range is
transmitted over the network.
