Problems With Wireless Connectivity
Problem Solution
When you turn on the CV30 after it
was suspended for a while (10 to 15
minutes or longer) and it no longer
sends or receives 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 CV30 is suspended.
The network connection icon is in
the taskbar or iConnect appears to be
communicating, but the host
computer is not receiving any data
from the CV30. 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.
The CV30 is not communicating
with the access point. Try these possible solutions in order:
• The CV30 is not connected to the access point. Make
sure the access point is turned on and operating. You
may also be using the CV30 out of range of an access
point. Try moving closer to an access point to
reestablish communications.
• Make sure the CV30 is configured correctly for your
network. The radio parameters on the CV30 must
match the values set for all access points the CV30
may communicate with. For help, see
“Setting Up
802.11 Radio Communications” on page 38 .
• The radio initialization process may have failed on the
802.11 b/g radio. Try resetting the CV30. For help,
see
“Resetting the CV30” on page 9 .
• If you have tried these possible solutions and nothing
happens, you may have a defective radio card. For
help, contact your local Intermec service
representative.
The CV30 is connected to the
Intermec Application Server or host
computer and you move to a new site
to collect data. You do not appear to
be connected to the network. 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.
