Frequently asked questions
Can your MoCA devices bridge 802.1q VLAN tagged packets and add VLAN tags?
Yes, our device can pass packets with VLAN tag. But, it can't add VLAN tags to the passed ethernet packets.
Is it full duplex?
MoCA is TDD (Time Division Duplex) technoligy. The 2.5 Gbps bandwidth is shared by all the devices in the same coaxial network. The elected controller device manages the Tx/Rx time slot allocation.
Will these work in an existing MOCA 2.0 environments? Obviously would have update at least 2 ends of the splits but would other ends be required to have 2.5 or would older MOCA adapters work with these?
Per the MoCA specification, MoCA devices are backwards compatible but not forwards compatible. This means, if a MoCA 1.1 device is talking to a MoCA 2.0 device (or 2.0 <-> 2.5, etc.) then the speed drops down in both directions to what the 1.1 device can support. At the same time, if you have another pair of nodes on the same network that both support MoCA 2.0, then that pair will communicate at 2.0 speeds.
The bad news is, some old MoCA devices are no longer maintained. We may meet some intworking issue. If you have such issue, please let us konw. We will try our best to help you.
Does the admin GUI also allow configuring the MoCA frequency channel you want the extenders to run on?
Yes, our products can support this. Our device can support MoCA D-band low, D-band high and D-band extend three configurations. By default, we enable all of them. It will setup a 5-channels connection, from 1125MHz to 1625MHz. We know that, many MSO use D-band low 1125MHz to 1225MHz to act as MoCA WAN. You can change our device to use D-band high only, from 1350MHz to 1675MHz, can build a 3-channels connection.
Does MoCA work with any network access technology?
Yes. MoCA technology works with any network access technology including fiber (GPON/EPON), DOCSIS, Ethernet and MoCA Access (see description later in this document).
But for DOCSIS, please pay attention to the upper frequency. Some DOCSIS 3.1 device can run up to 1218MHz. That will have overlap with MoCA(1125-1675MHz). Then you should add some POE filters to let them work together.

Is your product MoCA certified by the MoCA Certification Board?
Not yet. Now only Maxlinear is making MoCA2.5 chip. Their reference board has passed MoCA 2.5 certification. Our product is based on their MoCA 2.5 chip, MxL3710. So we don't need to do the certification again.
Does your MoCA adapter includes a filter inside the device already, such that connecting Modem/TV/etc to the second (marked TV) coaxial connector of the device will filter out MoCA frequencies?
Yes, our adapter has two internal band pass filters. One is for MoCA, between the MoCA chip and MoCA RF port. The frequency range is 1125 to 1675 MHz. Another is for TV, between MoCA RF port and the TV RF port. The frequency range is 5 to 1002 MHz. If your cable modem is using band less than 1002MHz. You can connect it to the TV RF port.
If the upper frequency of cable modem is higher than 1002MHz. Please don't connect it to the TV RF port. You need to install PoE filter to the modem and use a two-way splitter to connect RF outlet on the wall and the cable modem, MoCA adapter.
The admin / config page will not load at all, page just times out.
You need to set your IP address manually to 192.168.254.x, for example, 192.168.254.10, subnet 255.255.255.0, no gateway IP. You can refer to the follwoing link to set fixed IP to your computer.

Then connect your computer to the LAN port of MoCA adapter via ethernet cable.

Couple of quick questions around the firmware on the adapters： 1，Do you plan on issuing firmware updates? 2，How would I know they are available? 3，What level of support do you plan on providing for the adapters specifically for firmware or other types of updates?
1, Yes, If chip vendor updates SDK, I will release a new firmware based the new SDK.
2, We will put the new firmware onto our website, and send notifications to all the customers.
3, We will try our best to provide technical support to our customers, definitely the firmware upgrading will be included.
What problem does MoCA technology solve and how does it make the home network better?
MoCA technology is used as an in-home backbone to guarantee wireless connectivity. As consumers bring more devices into the home all yearning for bandwidth a wire is required to guarantee the wireless network. Though Wi-Fi has improved dramatically over the years, live content streaming, gaming, virtual reality and UHD format programming all strain even the most robust wireless network.
As a result of its high performance and reliability, and the support it provides for wireless networks, MoCA technology lowers the cost of managing the entire network, or total cost of ownership. This is important for both operators and consumers as guaranteeing the performance of the network and delivery of content reduces the need to continuously upgrade equipment and eliminates downtime from a non-performing network.
What are some of the alternative technologies and mediums available for home networking?
Large houses, MDU environments, thick building materials, and the nature of the in-home wiring can all affect the performance and satisfaction level of a home network.
Wi-Fi® technology is a shared medium so the more devices on the network, the less bandwidth available. A Wi-Fi-based network may not reach every room in the home, and signals will not go through walls. It is also prone to interference with a neighbor’s network.
Products using power line technology are easy to use and outlets are found in every room. Power line is also prone interference from everyday household appliances such as vacuum cleaners, microwave ovens and DECT phones. It is not an ideal medium for HD or ultra HD content distribution and it can be affected by condition and age of the wiring.
Ethernet (Cat5/6) are viable options and provide the performance and reliability of MoCA. However, Ethernet is not pre-installed in every home like coax, and every time there is an upgrade to the specification, a new category of wiring is required.
Unlike MoCA, which is a no new wires technology, Ethernet is a new wire every time.
When designing a home networking, products integrating both Wi-Fi and MoCA technology should be considered for maximum performance and satisfaction.
What is the bandwidth for simultaneous up/down transmission?
One network can has maximum 16 devices. All the devices share the 2.5G bandwidth, transfer traffic among them. So it is difficult to say up/down transmission. For example, if you connect two devices directly, when you do the test, you can get bi-directional 1Gbps throughput.
Does MoCA technology work on any type of coax?
Yes. If you can receive a TV signal, you can get MoCA. If the coaxial cable is 75Ohm, it is OK.
How fast can MoCA go?
MoCA 2.5 offers actual data rates of up to 2.5 Gbps. It is backward interoperable with MoCA 2.0 and MoCA 1.1.
MoCA 2.0 is capable of up to 1 Gbps actual data rates.
