Setup and Installation

Follow these steps to set up your TRENDnet TMO-312C MoCA 2.5 Ethernet Over Coax Adapter:

  1. Step 1: Connect the First Adapter to Your Router.

    Connect one MoCA adapter to your internet router. Use an Ethernet cable to connect the adapter's LAN port to an available Ethernet port on your router. Then, connect a coaxial cable from the adapter's MoCA Coax port to a coaxial wall outlet near your router.

  2. Step 2: Connect the Second Adapter in Another Room.

    In another room where you need a wired Ethernet connection, connect a second MoCA adapter. Connect a coaxial cable from the adapter's MoCA Coax port to a coaxial wall outlet in that room.

  3. Step 3: Connect Your Device.

    Use an Ethernet cable to connect the second MoCA adapter's LAN port to your network-enabled device (e.g., computer, gaming console, smart TV).

  4. Step 4: Power On and Verify.

    Connect the power adapters to both MoCA devices and plug them into electrical outlets. Verify that the LAN, MoCA, and Power LEDs on both adapters are lit, indicating a successful connection.

Operating Instructions

Once the MoCA adapters are properly installed and powered on, they will automatically establish a network connection over your existing coaxial cables. The adapters function as a transparent bridge, extending your Ethernet network without requiring additional configuration. Any device connected to the LAN port of a MoCA adapter will receive network access as if it were directly connected to your router via an Ethernet cable.

The LED indicators provide status information:

  • Power LED: Indicates the power status of the adapter.
  • MoCA LED: Indicates the status of the MoCA connection over the coaxial cable. A solid light typically means a successful MoCA link.
  • LAN LED: Indicates the status of the Ethernet connection to your device. A solid light means a successful Ethernet link, and blinking indicates data activity.

Maintenance

  • Cleaning: Use a soft, dry cloth to clean the adapter. Do not use liquid or aerosol cleaners.
  • Ventilation: Ensure the adapter is placed in a well-ventilated area to prevent overheating. Do not block the ventilation slots.
  • Environment: Avoid exposing the device to extreme temperatures, humidity, or direct sunlight.
  • Cable Management: Ensure all coaxial and Ethernet cables are securely connected and not excessively bent or strained.

Troubleshooting

Problem Solution
No Power LED. Ensure the power adapter is securely connected to the MoCA device and a working electrical outlet. Try a different outlet.
MoCA LED is off or blinking.
  • Verify that both MoCA adapters are powered on.
  • Check coaxial cable connections at both ends (adapter and wall outlet).
  • Ensure your coaxial network is compatible with MoCA. Some services (e.g., Directv, Dish Network, AT&T U-Verse) are not compatible.
  • If using splitters, ensure they are MoCA-compatible (5-1675 MHz or higher). Older splitters may block MoCA signals.
  • Consider installing a MoCA filter at your service entrance to prevent signals from leaving your home and to improve internal network performance.
LAN LED is off. Ensure the Ethernet cable is securely connected between the MoCA adapter and your network device. Try a different Ethernet cable or device.
Slow network speeds.
  • Check the quality of your coaxial cabling. Older or damaged cables can degrade performance.
  • Ensure all splitters in your coaxial network are MoCA-compatible and minimize the number of splitters.
  • Confirm your internet service plan supports the desired speeds.
  • Ensure your connected devices (router, computer) have Gigabit Ethernet ports to utilize the full speed of the MoCA 2.5 adapter.
