HTEM4 MoCA Adapter
MODEL # HTEM4
Please Note: If you are certain that the coax cables are tightly connected to the MoCA Adapter and your modem/router or device, it is possible that there is a problem with your Coax cable wiring and it is unable to support the frequencies required by MoCA technology.

Getting Started
Minimum System Requirements
- High-speed Cable Broadband Internet Service.
- Coaxial Cable TV wiring or coax outlets.
- Computer and devices with working Ethernet ports and Ethernet cables with RJ45 connectors to connect each device (for example, if you want to connect a gaming console, WiFi router or desktop computer).
Installation Guide
Please Note: Not all routers have MoCA technology built into the router. To check if your router supports MoCA, look for the “MoCA” symbol on the router packaging or consult your router manufacturer’s website. If your router does not support MoCA, you will need at least TWO MoCA Adapters to create a MoCA network connection.
Connect to Your Modem/Router
STEP 1

STEP 3
STEP 4
STEP 5
Please Note: If you have a TV or Cable Set Top box near your modem/router, you can connect it to your MoCA Adapter using the 2nd Coax Port marked “TV”, and use a second coax cable to make that connection.
STEP 1
Take one MoCA Adapter and an Ethernet Cable (a second Ethernet cable is provided in your Hitron HTEM4 package, if you purchased two HTEM4 MoCA Adapters).
STEP 2
Connect the Ethernet Cable from your Router/Access Point or Device (such as a WiFi booster/extender, gaming console, streaming TV player, laptop, desktop computer, etc.) to the second MoCA Adapter.
STEP 3
Locate a Coax Outlet in your home. Use the Coax Cable provided in the package to connect the Top Coax Port on the rear panel of the MoCA Adapter to the Coax Outlet. Make sure that the cable connection is finger-tightened to secure the connection.
STEP 4
STEP 5
Please Note: The MoCA light will turn Green when the MoCA network is in low speed, and Blue when the MoCA network is in high speed.

Product FAQs
How do I contact Technical Support?
Do I need more than one HT-EM4 adapter?
How fast is MoCA 2.5?
How many MoCA devices can I have connected to my home network?
Your network can connect a total of 16 MoCA devices including the adapters.
What is the maximum distance between MoCA devices?
Is the HT-EM4 compatible with satellite services?
Can I connect an OTA antenna to the adapter?
What end-devices are compatible with the HT-EM4?
Virtually any device that has an Ethernet port, including Xbox, gaming systems, computers, streaming media devices and more.
Why is my HT-EM4 not working with some MoCA 2.0 devices?
If the MoCA LED on the HT-EM4 is not lit up, or you cannot access the Internet when using the HT-EM4 with an existing MoCA 2.0 device, this is likely an interoperability issue with the driver/firmware on the MoCA 2.0 device. Some older MoCA 2.0 devices may have issues communicating because they are using much older driver/firmware versions. This is mostly seen with older single-channel MoCA 2.0 devices and can be resolved by simply upgrading to a newer driver/firmware. Please contact your MoCA 2.0 device vendor to see if there is a newer driver/firmware available for upgrade.
After connecting a splitter to my network, it no longer works. Why?
Why is my connection speed so slow?
- Run a speed test of your incoming broadband service to ensure that the broadband service is healthy.
- Check for faulty/outdated/incompatible coax splitters and connections within your MoCA network that may be restricting speeds.
- Check that other devices connected to your MoCA network are not hoarding available bandwidth.
- Check that the Ethernet cable is Cat5E/6 compliant.
- Check to confirm that your device has a Gigabit Ethernet port (1000Mbps) and not Fast Ethernet (100Mbps).
Doesn't the pre-existing coaxial cable already have the capability of providing Internet?
Why can’t I access the internet when connected to the HT-EM4?
If the POWER and LINK LEDs are on, but the MoCA LED is off:
— Ensure that the coax cable is connected to the RF port with the picture of a coax connector
If the POWER LED is on, but the LINK LED is offL
— Please wait up to 90 seconds for the HT-EM4 to establish a network connection.
Why do none of the LEDs turn on?
The HT-EM4 is not receiving power.
- Ensure that you are using the correct power adapter that came with the device. Using a power adapter other than the one that came with your HT-EM4 can damage the HT-EM4.
- Make sure that the power adapter is connected to the HT-EM4 and the electrical outlet correctly.
- Disconnect and re-connect the power adapter to both the electrical outlet and the HT-EM4.
- If none of the above steps solve the problem, consult your vendor as there might be a fault with the device.
