When you troubleshoot issues with a network cable, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
To test your setup components, try the following:
Use the network devices and network cables in another setup to see if the problem is with the components or the setup.
Use different network devices and network cables in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the network devices and network cables, make sure that the link LEDs (if present) turn on for both of the devices. This indicates basic network connectivity between the network devices. You also need to determine if your devices need a straight through or a crossover cable. For more information about straight through and crossover cables, see the following FAQ: http://www.startech.com/faq/network_cables_straight_through_vs_crossover
If the link LEDs are not illuminated or there are not any LEDs present, you will need to troubleshoot your devices. Alternatively, you can also use a network cable tester, such as the or .
