Network Problems
Basic Checks:
•Check the network activity lights to see if the computer is
communicating with the network.
•If you are using a modem and a network adapter, ensure that the
modem cable is not connected to the network adapter.
•Disconnect the network cable from the computer and check the cable
connector for bent or broken pins. Check for damaged or frayed cables.
•If the cable is not damaged, ensure that it is firmly connected to the
computer.
•Ensure that a hardware conflict does not exist between devices.
•Enter system setup and ensure that the appropriate network
operations settings are configured correctly.
•Verify the type of network device to which you are connecting the
computer. A hub typically operates at 10 Mbps. A switch operates at 10
or 100 Mbps. Ensure that the network adapter is configured for the
appropriate speed. See the network adapter diagnostics and
configuration utility in the Dell Diagnostics.
