This chapter includes some general troubleshooting guidelines, as well
as tips on certain common problems and how to overcome them.
Before you begin to trouble-shoot the interface, you should observe the
following guidelines.
▪ Don't overlook the obvious. With all the activity involved in
setting up a wireless network, it is easy to accidentally unplug an
antenna or disconnect power from a device. Check those things first.
(For a list of common problems, see the Troubleshooting Checklist
at the end of this chapter.)
▪ If something worked previously, but now has stopped working,
did you change something? If, for example, you change the
application running in the ControlWave Micro and re-download it,
and now it stopped working, it's possible that the change you made
to the application might have caused a problem.
▪ Adopt a systematic approach. Don't try to solve the problem by
changing several different things at once. Change one thing, see if it
causes an improvement, then make notes about what you did, then
you can try to make other changes. If you haphazardly begin
swapping hardware modules, re-routing cables, and changing
software parameters, you may end up in worse shape than when you
started, or you may end up masking symptoms of an underlying
problem.
▪ Try to isolate the problem. If, for example, you can communicate
with some wireless devices but not others, then concentrate on
what's different with the non-functional wireless devices, or their
configuration parameters. If you can't communicate with any
wireless devices, your might not have correctly configured network
parameters in the application, or there may be a problem at the field
link.
