Chapter 6 — Troubleshooting and Maintaining the CK30
CK30 Handheld Computer User’s Manual 99
Problems With Wireless Connectivity
Problem Solution
When you turn on the CK30 after it was
suspended for a while (10-15 minutes or
longer), it can no longer send or receive
messages over the network.
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 CK30 is suspended.
The no network connection icon
(
)appears on the status bar.The
CK30 is not communicating with the
access point.
The CK30 is not connected to the access point. Make
sure the access point is turned on and operating. You
may also be using the CK30 out of range of an access
point. Try moving closer to an access point to re-
establish communications.
Make sure the CK30 is configured correctly for your
network. The radio parameters on the CK30 must
match the values set for all access points the CK30 may
communicate with. For help, see “Configuring
802.11b/g Radio Communications ” on page 41.
If you have an 802.11b radio, the radio initialization
process may have failed. Try resetting the CK30. See
“Booting the CK30” on page 102.
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.
The CK30 is connected to the DCS 30X
or Intermec Gateway 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.
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.
The network connection icon is in the
status bar, but you cannot establish a
terminal emulation session with the host
computer.
There may be a problem with the host computer, a
problem with the connection between the DCS 30X or
Intermec Gateway and the host computer, or a problem
with the connection between the access point and the
host computer. Check with your network administrator
to make sure the host is running and allowing users to
login to the system.
