Troubleshoot Your Mobile Computer

Use the troubleshooting tables in this section to fix problems with the

Wi-Fi connection, 802.1x security, the imager, or general problems

with operating the mobile computer.

If you send the computer in for service, it is your responsibility to save

the computer data and configuration. Intermec is responsible only for

ensuring that the hardware matches the original configuration when

repairing or replacing the computer.

minutes or longer), it can no longer

send or receive messages over the

network.

Host may have deactivated or lost current terminal

turn off the “Keep Alive” message from host to maintain

the TCP session while the computer is suspended.

The computer is connected to the

network and you move to a new site to

collect data. Your computer now shows

you are not connected to the network.

Move closer to an access point or to a different location

to reestablish communications until you reconnect with

the network.

The computer appears to be connected

to the network, but you cannot

establish a terminal emulation session

with the host computer.

There may be a problem with the host computer, or with

the connection between the access point and the host

computer. Check with the network administrator to

make sure the host is running and allowing users to log

in to the system.

The computer appears to be connected

to the network, but the host computer

is not receiving any information from

the 70 Series computer.

There may be a problem with the connection between the

access point and the host computer. Check with the

network administrator or use your access point user’s

manual.
