How to troubleshoot connection problems with MoCA (goCoax WF-803M) and basic MoCA setup requirements

This video will walk the viewer through setting up the simplest type of MoCA connection and what to look for when things are not working immediately. #moca #gocoax #homenetwork

We also demonstrate what to look for when the coaxial cables are split or routed to a central splitter and we need to confirm the splitter compatibility with your MoCA devices.

When all of these fairly simple troubleshooting steps do not do the trick, you may have a truly faulty device.
