Why Your HTEM4 MoCA Connection Isn't Working – 6 Common Fixes

If your HTEM4 MoCA adapters aren't working, review this list of quick fixes.

1. Coax outlets aren’t connected.

  • All outlets must be on the same continuous coax line.

2. Router doesn’t support MoCA.

  • You need two adapters unless your router is MoCA-enabled.

3. Splitter is blocking MoCA

  • Replace the "bad splitter" with a MoCA-compatible splitter (5-1675 MHz).

4. Amplifiers or filters are blocking the signal.

  • MoCA signals can be stopped by coax amplifiers or filters. Please remove the coax amplifiers or filters.

5. Ethernet cable is in the wrong port.

  • Make sure Ethernet goes from your router to the HTEM4 adapter, and from the adapter to a device.

6. Defective adapter or cable

  • Test each HTEM4 unit and Ethernet cable by following the instructions found here
