Chapter 5 — Troubleshooting and Maintaining the CN2A
102 CN2A Mobile Computer User’s Manual
You receive a message saying, “The
server certificate has expired or your
system date is incorrect” after you cold
boot the CN2A. The date and time on the CN2A are not saved through
a cold boot. You need to re-enter the date and time
and then save your changes. For help, see Step 4 on
page 113.
You are setting up multiple access
points in a network, with different
SSIDs, and the connection fails. The CN2A does not save WEP key values when you
change the SSID. Re-enter the WEP key value after
you change the SSID and save your changes. You
should now be able to connect to the different access
points.
Problems With Wireless Connectivity
Problem Solution
A Network Connection icon ( , ,
, or ) appears on the task bar, but
the host computer is not receiving any
data from the CN2A.
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.
When you turn on the CN2A after it
was suspended for a while (10-15
minutes or longer), it can no longer
send or receive messages over the
network. Try these possible solutions in order:
• The CN2A may not be recognizing the network
card. Turn off the CN2A, and then turn it on
again.
• 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 CN2A is
suspended.
