It's taken almost a year, but D-Link is finally shipping its
DXN-221 Coax Ethernet network adapter. The
MoCA-certified box does exactly what it says -- it turns your existing coax cabling into a giant Ethernet network without interfering with TV signals, allowing you to get hardwired network speeds anywhere in your house without having to run Cat6. A pair will set you back $239 at retail, but it looks like D-Link is selling them direct for $156.

So what are the Speeds ? 10/100/ Gigabit ? this could be cool
Jon @ Apr 20th 2009 8:15PM
I can see its 100mps from the picture ..

MoCa actually is rated up to over 220mbps. But it does say that the ethernet interface is 10/100, so I am not sure if that is a limiting factor.
But if you want to experiment with MoCa cheaper go to ebay and buy 2 motorola nim100s. Same principle, much cheaper (can be found on ebay for less than $50 each).

So do you use the Motorola boxes and/or these boxes as 'bridges'? Meaning your run the original cable into this box to get the 'feed' and then run the coax out to your 'normal' cable box but this allows you to use plug in a network device into this box and utilize cable internet (if you have cable internet)? If so, can you attach a switch to it to allow multiple devices to plug-in?

@Wryker
These boxes effectively work as bridges between 2 segments of an ethernet network. In my example I have an office with my Modem, Router, computers, laptops, etc. I have a nim100 connected to the network & coax there, then I have another nim100 in my entertainment center connected to a switch. I then have my TiVo, my PS2, my pch a100, & my wireless access point also connected to the switch. Everything works seemlessly together. You wouldn't need a switch if you only had one device to connect.

@scyber
do you need two boxes? i ask since i already have my cable network box upstairs and my computers etc connected to a router off the cable network box. downstairs we also have cable so could i get one of the nim100's and run that cable through it to get access to the network?

I apologize if this is off-topic, but does anyone know how to do the reverse. I have a room that I've wired with CAT6, but no coax, and I need to put a TV in it.
Pacey @ Apr 22nd 2009 9:56AM
Many companies make baluns that let you convert coax to Cat5e/Cat6 and back again. It's not on the network and needs to be point-to-point. So if you have coax near your networks central location you can sacrifice one of the network lines to get TV to wherever you need it

You will somehow connect to your router. That's where your network is. Hence the need for second box.
Wryker @ Apr 21st 2009 2:40PM
I meant since I already have the cable box w/the cable internet already in the house so i would only need one moto box to connect my cable downstairs?

I have a pair of Gefen Ethernet over coax box purchased from BeachAudio.com for similar price. It works out very well. I did a file transfer test using Windows XP. I got about 70mbps real world performance for Windows file copy which is very close to what 100mbps LAN can offer. The actual link speed is about 160mbps on my setup over about 200 to 300 feet of coax running out side of my house (my existing cable run).
From the review I read, typical MoCA setup is about 70 to 80 mbps for one connection and about 130 mbps for multiple connections.
The Gefen receiver box comes with 4-port switch, perfect for my HT setup.
This setup beats any wi-fi networking as far as I can see in the area of consistant throughput, low ping and speed.
foxb @ Apr 21st 2009 2:46PM
No, you will have to connect to your router's LAN side, not internet side. Hence you need another box. There is no network on coax cable side by itself unless you are going to setup a second cable modem and account.

if i knew how to PM you i would - i'm not clear on the set up you're speaking of. How can one 'box' in a different room allow internet access to a 'box' in a different room? I have the comcast internet/phone box upstairs w/my router and a bridge (too many items i wanted to have wired in) while downstairs we also have cable and i've configure the PS3, etc wireless but if there was a way to put a 'box' downstairs that'd allow for 'wired' connections that is what i'm looking to do.
