DIRECTV Broadband DECA Ethernet to Coax Adapter (DCA2SR0 ) Generation II

Pros:- CHEAP!- No config Setup- Speeds are what I'd expect from a 100mbps connection- Solid constant connection unlike Powerline networking like HomePlug which constantly droppedNeutral:- 2-6ms latency added in. Overall this isn't a big deal, but worth noting.Cons that aren't a big deal for me:- No configuration to ensure the connection is encrypted with a unique key.- By design this will not work with cable TV on the same coax. If it's isolated from cable TV signals, it works fine.For the price, I'm not complaining about its simplicity. I'm just happy it works and doesn't drop the connection unlike my HomePlug Powerline adapters. I'm currently running these point to point so there's only two adapters and not 3+ with splitters; I can't comment how more than two would work out, but my network switch doesn't have an issue.I rent a house and it isn't wired well. I'm not interested in getting the landlord's approval along with spending my own money to upgrade his house. I tried powerline adapters, but the connection frequently dropped even in a five year old house. One of the previous tenants had satellite TV with RG6 ran in additional areas that weren't originally wired. MOCA is way too expensive for what it is and these DECA adapters are pretty much the same thing on a different frequency range.

said it would work from cable to ethernet but doesnt work that way it may work great with direct tv but not from cable to work

I would have given it 5 stars, if it weren't because one of the two units that I received is "-18", which is only $4 at Amazon, and is not "-1" as seller described. Luckily, with my own Ethernet cable, the pair works fine, and Amazon should pay me back the $4 difference.I switched to Optimum. Optimum Cable Modem and Router are two separate units. Phone jack is on Modem and connection between the two is with an Ethernet Cable. The Modem must be placed near the phone connection, so that router cannot be at an ideal location for WiFi, unless I run a new Ethernet cable, as the house is only pre-wired with coaxial cables.So, I need an EoC solution, and after studying reviews of DIRECTV DECA in Amazon and various websites, it is not conclusive whether DECA can serve as EoC, yet I decide to give It a try.I connect one DECA on each end of an existing coaxial cable in house,power them up with supplied ESP10 12Vdc 1.5A power adapters,use an Ethernet cable to connect a Gigabit port on the Router to1st DECA,wait network light on both DECAs to stop flash and be solid on, which takes a while,then I connect an Ethernet cable from 2nd DECA to a Laptop PC, it indicates 100M network connection is established, and I have internet access.I subscribe 50/25 Internet speed, and speed test on PC is 58/28 MBit.I then move the router to farther end of the coax cable, so as to insert EoC between Modem and Router,connect Ethernet cable from 1st DECA to Modem Ethernet port,connect Ethernet cable from 2nd DECA to Router input.After system initialization, speed test result with PC wired to router is 59/28 MBit. 5.0 GHz WiFi speed is 43/25, which is consistent with original results.It worked flawlessly for 10 days, then all the suddenly "there is no internet access". The problem was "DNS server not responding", which eventually traced back to EoC. After reboot both DECAs and router, things are back to normal. It has been 4-weeks, there is no other service interruptions, other than above mentioned reboot on 10th day. There was a brief power outage, the DECA handshake was the last to establish, once it did, the router internet access indicator lit up rather quickly.It can be safely concluded that a pair of DECA can serve as a $16.5, 100 Mbit EoC solution, if occasional reboot is tolerable. I am glad DIRECTV makes DECA, although EoC probably was not their original purpose.Most other EoC solutions will be more expensive, while EoP (over power line) is susceptible to AC line noise, so it is not as reliable as EoC, and is also more costly.I have a dedicated coaxial cable for EoC, depending on the TV system, the EoC signal may or may not be able to mix back into cable signals due to potential spectrum conflict.The power consumption is 3W for each DECA unit, which is ~$0.5/mon, if you care. A 12Vdc 0.5A, F-connector power adapter should work more efficiently. If you have it, then buy DECA w/o the supplied EPS10 adapter for slightly less.

I do not have direct TV, what I have if a room that does not like WiFi, and a spare cable line running from point A to B. I bought 2 of these for the 1 run. Basically to use it in this manner, you have 1 on each side of the cable coax line, and both sides need the power hooked up. Past that 1 side gets hooked up though a Cat 5 or more cable going to the router or switch you use, and the other side just goes to the unit you want to have solid wired internet. After that is done, it just takes a minute or two for the units to talk to each other; then both lights will be green- and you have a connection. This line passes everything I have hooked it up to for testing, laptops, media devices like apple TV and rokus. It even passes the DLNA and it works great! Instead of it taking 20 seconds or more to have spotty videos through Netflix and my DLNA server, the videos start up in under 3 seconds! The time saved is life saving when it comes to 3 small children, they have no patience anymore. So to answer your question 2 of these do what the much more expensive adapters that are made specifically for this purpose do. So save yourself $100+ and get these instead, they are even a bit smaller than the pricier units!

This product doesn't solve my problem, and I will be returning it.

The units worked well but unfortunately my broadband provider has to be changed because of way too slow speed for streaming.

My house is wired for Cat-5 and Coax with all lines running through a central box. In the room I'm using for an office the Ethernet port isn't convenient for my desk, but the coax port is. I didn't want to have two sockets in my room dedicated to the powerline any longer, so I was looking into MOCA adapters until I found this. (Note: MOCA can get you true Gigabit speed, this is regular Base100-T speed.) As I don't have any intention of using cable or broadcast on the drop, this solution works well. Just hooked two adapters together and no problem.It only took me 5 seconds for 2 adapters to establish a handshake over about 50 ft of cable in the the walls.Yeah, the boxes and power supplies are bulky, but so are MOCA adapters.Update:I've been running one for a couple months. I'm getting a 96 Mbps one-way speeds on my setup. It's been reliable as well.
