Problems with Wireless Connectivity

Problem
When you turn on the CK60 Computer after it was sus-
pended for a while (10-15 minutes or longer), it can no
longer send or receive messages over the network.
The No Network Connection icon appears on the status
bar. The CK60 Computer is not communicating with the
access point.
The CK60 Computer 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 is now replaced with the No Network
Connection icon.
The Network Connection icon is in the status bar, but
you cannot establish a terminal emulation session with
the host computer.
The Network Connection icon is in the status bar, but
the host computer is not receiving any data from the
CK60 Computer.

Solution
The host may have deactivated or lost your current termi-
nal emulation session. In a TCP/IP direct connect net-
work, you need to turn off the "KeepAlive" message (if
possible) from the host so that the TCP session is main-
tained while a CK60 Computer is suspended.
The CK60 Computer is not connected to the access
point. Make sure the access point is turned on and oper-
ating. You may also be using the CK60 Computer out of
range of an access point. Try moving closer to an access
point to reestablish communications.
Make sure the CK60 Computer is configured correctly
for your network. The radio parameters on the CK60
Computer must match the values set for all access points
with which the CK60 Computer may communicate. For
help, see "Configuring 802.11b/g Radio Communica-
tions" on page 53.
If you have an 802.11b radio, the radio initialization pro-
cess may have failed. Try resetting the CK60 Computer.
See "Resetting Your CK60 Computer" on page 3.
If you have tried these possible solutions and the No Net-
work Connection icon still appears, you may have a
defective radio card. For help, contact your local Intermec
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 reestablish 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.
There may be a problem with the host computer, a prob-
lem with the connection between the Intermec Applica-
tion Server and the host computer, or a problem with the
connection between the access point and the host com-
puter. Check with your network administrator to make
sure the host is running and allowing users to login to the
system.
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 administra-
tor 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 com-
puter. Check with your network administrator or use
your access point user's manual.
