Basic Connection
Checks The Router has been designed to aid you when detecting and solving
possible problems with your network. These problems are rarely serious;
the cause is usually a disconnected or damaged cable, or incorrect
configuration. If this section does not solve your problem, contact your
supplier for information on what to do next.
Perform these actions first:
■
Ensure all network equipment is powered on.
■
Power each piece of network equipment off, wait about five seconds
and then power each one on.
CAUTION: Do not power the Router off and then immediately on. Wait
about five seconds between power cycles.
Check the following symptoms and solutions:
■
Check that the Router is connected to your computers and to the
telephone line, and that all the equipment is powered on. Check that
the LAN Status and SYNC LEDs on the Router are illuminated, and that
any corresponding LEDs on the NIC are also illuminated.
■ Ensure that the computers have completed their start-up procedure
and are ready for use. Some network interfaces may not be correctly
initialized until the start-up procedure has completed.
■ If the link status LED does not illuminate for a port that is connected,
check that you do not have a faulty cable. Try a different cable.
