DIRECTVDIRECTV Broadband DECA Ethernet to Coax Adapter - Third Generation (with AC Power Supply)

Been using these for years. As long as you only need 100mbps they’re fine. I have four going now on one coax “network,” no issues. I get nearly 100mbps and no packet loss.These are not “point to point,” you can put three on the same circuit, it’ll work.They can be USB powered, but *not* by a “dumb” power supply. I don’t know why. But if you run a USB micro cable to an actual “device” (computer, game console, etc.) it powers it fine. From a normal 5V power supply, nope. So if you’re having that problem, there’s your answer.Overall a great and cheap way to use existing wire as long as the speed works for you.

I bought 2 of these devices as house has no ethernet wiring and it does serve the purpose for ethernet over coax (old cable TV cables). The highest speed you can get is close to 100Mb even when I connect it with 1 Gb router on one end and just computer on the other end (with 1 Gb CAT6). I hoped for more, but better than nothing.

Facile à installer d'autant plus que les cable necessire sont fournis avec

This deca adapter solved a big issue. I upgraded my food service and the new box has only Ethernet out, not coax. During the midst of COVID, Verizon wouldn’t pass the cable to my basement, where my router was. This deca adapter did the trick. I used it as a bridge to get Ethernet over coax to my house. Please be aware that you may need a proper coax splitter to match the frequency of the adapter . They are very inexpensive at about $6. Also you will need 2 of these deca adapters , one at the source (Ethernet in, coax out) and one at the destination (coax in, Ethernet out). Also the max speed is between 80-95Mbps. This is plenty for HD video and gaming and working and video conferencing at the same time.

I bought a pair of these to try to make for a stable internet connection in an area that had spotty WiFi coverage, and where it is not easy to run an Ethernet connection, but cable wiring already exists. I tried connecting these using the existing cable wiring in my house and could not get a connection. My computer indicated it was connected, but that the device IP was invalid. So I tried a “best case” test by connecting the pair to each other using a 6’ length of coax. I tested the ethernet connection without the DECA in place and got 350 Mbps. I disconnected the cable from my laptop, plugged it in to one of the DECA adapters, and used another Cat6e cable to connect the other DECA adapter to the laptop, then ran the same speed test. With the adapters, speed dropped to 30 Mbps. And that’s over just 6’ of coax, no splitters, no other factors. I expected something closer to 100 Mbps in this setup. I don’t need this connection to be blazing fast, but 1/3 of the stated speed in an ideal scenario just isn’t going to cut it.
