Solution
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 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 46.
• If you have an 802.11b radio, the radio
initialization process may have failed. Try resetting
the CK30. See "Booting the CK30" on page 128.
• 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.
There may be a problem with the host computer, a
problem with the connection between the Intermec
Application Server 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.
If you are having problems sending or receiving data through the
integrated serial port on the CK30, check these possible
problems:
• Make sure the CK30 is connected to the PC, host computer,
or RS-232 serial device using the appropriate cable adapter
and null modem cable.
