3.1 Improper Network Cabling and Topology

Improper network cabling or topology setup is a common cause of poor network performance or
even network failure.

CORRECTIVE ACTION
Using faulty network cables may affect data rates and have an impact on your network
performance. Replace with new standard network cables.
Non-standard cables may increase the number of network collisions and cause other
network problems that affect your network performance. Refer to
for more information on network cable types.
If you use longer cables than are needed, transmission quality may be affected.
The network cables should not be longer than the limit of 100 meters.
Too many hubs (or repeaters) between the connected computers in the network may
increase the number of network collision or other network problems. Remove unnecessary
hubs from the network.
A data path loop forms when there is more than one path or route between two networked
computers. This results in broadcast storms that will severely affect your network
performance. Make sure there are no loops in your network topology.
