Defective cables. Replace the cable if it is worn or defective.
An Ethernet cable may not be firmly connected at both ends. Secure the cable at both
ends. Often, just reseating the cable into a connector is all that is required.
The NIC may be bad or the network cable connected to it may be the wrong kind (for
example, it might be a straight-through cable when a crossover cable is required). If you
have another NIC and cable available, try using them instead.
The DHCP server that would automatically assign IP addresses is not configured for
