IMPORTANT!!! THESE DECA UNITS CAN ONLY BE POWERED BY A SMART DEVICE LIKE A USB PORT OF A SMART TV, USB PORT OF A LAPTOP, USB POWER OF A ROUTER, ETC. REGULAR WALL ADAPTER LIKE FOR YOUR PHONE WILL NOT WORK. This unit can be used to run Ethernet over existing coax cable. The DECA network is a shared 200Mb/s, or the same speed as full duplex 100Mb/s Ethernet. Great for using right behind a router to pump internet over coax for a Whole Home DVR or Connected Home Setup This unit will connect to your router via an Ethernet cable, and then into an open port on one of your sws splitters to get the internet into the coaxial cable for the entire system. Installation over an existing coax cable is simple. Place the first unit near a CATV output, such as a router, which already has an internet connection. Attach the coax line, the internet source CATV, and a power supply to the first unit. At the other end of the coax line, attach the second unit, and plug it into a power supply. Within a minute or so the indicator light will stop flashing flash and stay solid indicating an established link. This second unit now offers a CATV output with internet speeds of up to 100 Mb/s. This adapter is used to bring an internet connection to SWM enabled DIRECTV receivers on a network. You wont have to run Ethernet cable throughout your home or business thanks to this small system add-on.
Enjoy Pandora, PC Media Sharing and more when you bring internet to your DIRECTV receiver using this handy adapter.

They wouldn't establish a connection by just connecting a 5V DC power supply to the micro USB connection. I assume they need a USB data connection also if you want to use that method of powering the devices. I think they use some power saving protocol for communicating if you power them through the USB. Which means they would need drivers for that kind of configuration.
The devices I wanted to connect in the attic (USB TV tuners) and basement (ethernet network) didn't have that capability so I abandoned the micro USB connection for powering these. Since I wanted to use one of these devices up in the attic as a simple fast ethernet connection to my basement media center, I had to run 12V DC up on the same coax cable I used for the data. I used a Satellite/TV splitter with DC pass capability on the satellite path in both the basement and the attic to inject and strip off the DC from the coax. There are no RF or data signals transmitted over the satellite frequencies, so this works well as a straight DC power injector/bias tee.
I didn't have an appropriate DC connector for the unusual 12V DC port on these devices so I disassembled the outer case and desoldered the 12V DC port from the PCB. The only way I could get the connectors off the board was to carefully cut the metal ground cover off the connector and then heat each solder connection while gently pulling it out of the tiny hole that it was soldered into. I soldered speaker wire to the power connections and a more standard DC port to the short piece of speaker wire to be able to inject the 12V DC to the device. The installation required a bit of soldering/desoldering capability and being handy with small cutoff tools. The end result has been installed for a few weeks and is running flawlessly connecting my two TV tuners mounted directly on my antennas in the attic, to my media server in the basement. This exercise allowed me to isolate and use two antennas one aimed at local and one aimed at distant transmitting towers covering multiple channels the are bumping up to one another in the TV band - all without any filtering or concern about cable length to eliminate destructive interference. It also allowed me to connect the tuner right at the antenna - eliminating virtually all cable loss so I could get every last dB the antenna is capable of.
I was messing around with different USB chargers and cords, just to experiment. I was able to get it to work with a USB hub connected to an old unused cell phone and Samsung charger.
FYI, the 12v adapter has a proprietary connector. It's NOT a standard 2.1 or 2.5mm barrel.
However, if you're looking for throughput and latency comparable to CAT5e/CAT6, just go with MoCA. My latency and down speed took a large hit with DECA (~60Mbps DL and ~50ms ping) vs CAT6 (~600Mbps DL and ~10ms ping), whereas the significantly more expensive MoCA got me close to CAT6 quality. (~500Mbps DL and ~15ms ping)
In summary, DECA for FaceBook and Netflix? Thumbs up. DECA for online gaming or large downloads? Thumbs down.
That should be very explicit in the description instead of being buried in the Q&As (hence the 4 * instead of 5, would have given 4.5).
I wanted to get wired Ethernet from a new fiber gateway to the old Wi-Fi router using the existing coaxial cable.
It did not work when I tried ALL the USB phone chargers we have (iPhone, Samsung, generic,...). Power led stayed off.
Before giving up, I went back to the Q&As section and there it was: you have to hook it up to a USB port on a TV or a computer. I did it on both sides, on the USB ports of the gateway and the router. And I get ~ 94Mbps for both download and upload.
So I would say it works very well once you get it to work.

2) I found that one of the deca devices is running in my LAN with an IP address. Attempted to login to the IP address portal with admin user password but unable to access. I am suspicious of what this portal is doing and if it is retransmitting data to the internet. I proceeded to block the IP address from accessing the internet for now.
