Intermec cn30 User Guide

You are setting up multiple access points in a network, 
with different SSIDs, and the connection fails.

The CN30 Computer does not save WEP key values 
when you change the SSID. Reenter the WEP key value 
after you change the SSID and select Apply Network Set-
tings from the 802.11 Radio menu. You should now be 
able to connect to the different access points.

You receive a message saying “The server certificate has 
expired or your system date is incorrect” after you per-
form a cold-boot on the CN30 Computer.

The date and time on the CN30 Computer are not saved 
when a cold-boot is performed. You need to reenter the 
date and time and then select Apply Network Settings 
from the 802.11 Radio menu.

When you turn on the CN30 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 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 CN30 Computer is suspended.

The No Network Connection icon appears on the status 
bar. The CN30 Computer is not communicating with 
the access point.

The CN30 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 CN30 Computer out of 
range of an access point. Try moving closer to an access 
point to reestablish communications.

Make sure the CN30 Computer is configured correctly 
for your network. The radio parameters on the CN30 
Computer must match the values set for all access points 
with which the CN30 Computer may communicate. For 
help, see “Configuring 802.11b/g Radio Communica-
tions” on page 108.

If you have an 802.11b radio, the radio initialization pro-
cess may have failed. Try resetting the CN30 Computer. 
See “Resetting Your CN30 Computer” on page 16.

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.

The CN30 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.

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.

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 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.
