Chapter 5 — Troubleshooting and Maintaining the Computer
82 741 and 751 Color Mobile Computers (Windows Mobile 5.0) User’s Manual
Problems With Wireless Connectivity
Problem Solution
When you turn on the computer
after it was suspended for a while
(10-15 minutes or longer), it can
no longer send or receive messages
over the network.
Host may have deactivated or lost current terminal
emulation session. In a TCP/IP direct connect
network, turn off the “Keep Alive” message from host
to maintain the TCP session while the computer is
suspended.
The Network Connection icon is
in the toolbar, but you cannot
establish a terminal emulation
session with the host computer.
There may be a problem with the host computer,
with the connection between the Intermec
Application Server and the host computer, or with
the connection between the access point and the host
computer. Check with network administrator to
make sure the host is running and allowing users to
login to the system.
The Network Connection icon is
in the toolbar, but the host
computer is not receiving any data
from the 751.
In a UDP Plus network, there may be a problem with
the connection between the Intermec Application
Server and the host computer. Check with network
administrator or see the users 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 network administrator or use
your access point users manual.
Problems While Configuring 802.1x Security
Problem Solution
The 751 indicates that it is
authenticated, but it does not
communicate with the host.
Make sure the 751 IP address, host IP address,
subnet mask, default router are configured for
network.
The 751 does not appear to be
authenticating and a network
connection icon does not appear on
the toolbar.
The 751 may not be communicating with the
access point. Make sure the 751 network name
matches the access point network name (SSID).
802.1x security network may not be active. Make
sure the server software is properly loaded and
configured on the server PC. See server software
documentation for help.
A network connection icon appears
in the toolbar, but then disappears.
The 751 may not be communicating with the
intended access point. Make sure the 751 network
name matches the access point network name.
Default network name is “INTERMEC.
Access point may not be communicating with
server. Ensure the access point is turned on,
properly configured, and has 802.1x security
enabled.
You are setting up multiple access
points in a network, with different
SSIDs, and the connection fails.
The 751 does not save WEP key values when
changing the SSID. Reenter the WEP key value
after changing the SSID and save your changes.
You should now be able to connect to the different
access points.
