Troubleshooting
1. Everything is hooked up but Rj45 port is not working. What should I do ?
When you troubleshoot issues with a network port, there are some quick tests that you
can compete 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:
1) Ethernet cables
2) Network devices
3) Computer system
To test your setup components, try the following:
1. Use the Ethernet cables, network devices, and computer system in another setup to
see if the problem is with the components or the setup.
2. Use different Ethernet cables, network devices, and a different computer system 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:
1. Test each cable individually
2. Use short cables when you are testing.
2. Having trouble with video or audio playback ?
