1. Cable Problem: Cables that connect different parts of a network
can be cut or shorted. A short can happen when the wire conductor comes
in contact with another conductive surface, changing the path of the
signal. Cable testers can be used to test for many types of cable problems
Cut cable, incorrect cable connections, Cable shorts, Interference level,
2. Connectivity Problem: A connectivity problem with one or
more devices in a network can occur after a change is made in configuration
or by a malfunction of a connectivity component, such as hub, a router
or a Switch.
3. Excessive Network Collisions: These often lead to slow connectivity.
The problem can occur as a result of bad network setup/plan, a user
transferring a lot of information or jabbering network card.
NB: A jabbering Network card is a network card that is stuck in a transmit
mode. This will be evident because the transmit light will remain on
constantly, indicating that the Network card is always transmitting.
4, Software Problem: Network problems can often be traced to
software configuration such as DNS configuration, WINS configuration,
the registry etc.
5. Duplicate IP Addressing: A common problem in many networking
environments occurs when two machines try to use the same IP address.
This can result in intermittent communications.
