For information about the network status indicator(s) on
your notebook, refer to your model-specific documentation.
■
Verify that the network cable is a Category 5 (CAT-5) twisted-pair
cable.
■
Verify that one end of the network cable is securely plugged into
the RJ-45 (network) jack on your system and that the other end of the
cable is securely connected to an Ethernet network wall jack (not to
a digital telephone wall jack or other similar-looking wall jack).
■
Try connecting to a different Ethernet network wall jack that you
know is functioning correctly.
■
If you are plugging directly into a hub or switch, make sure the hub or
switch is turned on and that you are not plugging into the uplink port.
Connection occurs, but network seems
inactive
■
Using the Device Manager utility in your operating system, verify
that the network adapter device driver is properly installed.
■
Verify that the TCP/IP or other required networking protocol is bound
to the network adapter and properly configured.
■
Verify that you are using a valid address for your network. For
network address information, contact your network administrator.

Verify that the network resource you are trying to reach is on and
connected to the network.
