Solutions for Common Problems
Basic Troubleshooting
Network problems are often caused by cabling errors, conflicts
with other devices installed in the same computer, or software that
has been configured incorrectly. If you encounter a network
problem, use the following checklist to identify and correct the
problem.
K Make sure the cable is within ANSI/IEEE 802.3 and ISO/
IEC8802-3 Ethernet, or ANSI/IEEE802.3u Fast Ethernet
standards for the type of network you are using. For 10BASE-T
and 100BASE-TX operation, the maximum UTP cable length is
100 meters. For 10BASE-T operation (SMC9432BTX model),
the maximum thin coax cable length is 185 meters.
K Make sure the card is securely seated in the expansion slot.
K Make sure the network cable is securely attached to the card's
connector.
K Make sure the correct network operating system driver is
installed.
K Make sure the computer is receiving power. If you suspect the
power outlet to be faulty, plug another device into it to verify
that it is working. Check to see whether the outlet is controlled
by a wall switch.
K If you set your network card's speed manually, be sure the
speed selected for the hub and card (10 Mbps or 100 Mbps)
match.
