Check cabling

Ensure that the link LEDs at both ends of each Ethernet cable are on. If the link LEDs are not on, then ensure that the cross-over cables are not being used in error. Try different cables if the link LEDs do not come on.

Use proper cables rated for at least 100 Mb/s; for example, category 5 UTP cables.

Check end-to-end connectivity

Ensure that any intermediate Ethernet switches or hubs, routers, and firewalls are properly connected and configured.
