Chapter 3 Troubleshooting
3.2  Improper Network Cabling and Topology
Improper network cabling or topology setup is a common cause of poor network performance 
or even network failure. 
Figure 8   Troubleshooting Improper Network Cabling and Topology
PROBLEM
CORRECTIVE ACTION
Faulty cables
Using faulty network cables may affect data rates and have an impact on your 
network performance. Replace with new standard network cables. 
Non-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. 
Cabling Length  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 
between the 
computers in 
the network 
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 loop in the 
data path
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.
