Make sure you are using Category 5 cable for 100 Mbps connections, and that the length of any
cable does not exceed 100 m (328 ft). Inspect all network cables and connections. Make sure the
network cable is securely attached to the card's connector.
Possible Solution:
Make sure the correct network card driver is installed for your operating system. If necessary, try
uninstalling and then reinstalling the driver.
Possible Solution:
If the network card's speed or duplex mode has been configured manually, make sure it matches
that of the attached network device port. It is recommended to set the card to auto-negotiation
when installing the network driver.
Possible Solution:
The port on the network device that the card is attached to may be defective. Try using another
port on the device.
Possible Solution:
If you cannot access a Windows or NetWare service on the network, check that you have enabled
and configured the service correctly. If you cannot connect to a particular server, be sure that you
have access rights and a valid ID and password.
Possible Solution:
If you cannot access the Internet, check your network settings and verify that TCP/IP is installed
and properly configured.
Possible Solution:
Some network devices require a crossover ethernet cable to be used. Check the documentation of
your network devices to verify what type of ethernet cable must be used.
