D-Link introduces DXN-221 Coax Ethernet Adapter Kit

D-Link's no stranger to HD streaming, and the outfit is proving that it's still got game by announcing the Coax Ethernet Adapter Kit. The Multimedia over Coax Alliance (MoCA)-certified package consists of two DXN-220 adapters, each of which boast coaxial F-type connectors and an Ethernet port meant to give internet / network access to various rooms without worry over wireless connections flaking out on you. As you can tell, this one was designed to expand home networks without requiring any additional wiring (if you're pre-wired for cable, that is), and being that it operates in the 800MHz to 1,500MHz range, there won't be any interference with cable TV transmissions or the like. The DXN-221 kit -- which includes a pair of the aforementioned adapters -- will be available in Q3 for $199.99, while individual adapters can be purchased for $109.99 apiece.

Back to the Future, Baby! Bring on the 10Base2!

[tom @ May 28th 2008 10:06AM]

it's okay. Who knew the same phone line giving you 9600 baud/s in the 90s can now have speed of 7+mbps. =)

[MattyG @ May 28th 2008 10:32AM]

they'll be bringing back bnc next, just as i'm ripping it out of my work place

Go on eBay and grab a Motorola NIM for half the price.

[Logboy @ May 28th 2008 11:08AM]

Two NIMS.....

[CapWKidd @ May 28th 2008 6:21PM]

Yeah, how are theses different from Motorola NIMs?

[Mo @ May 28th 2008 10:18AM]

So how much speed is this ? Mb/s? Do you guys think it will be a good alternative then paying to place ethernet in my new house? That must cost a lot!

[jackcutts @ May 28th 2008 10:28AM]

Just get a Powerline ethernet solution. I have been using Netgear's XE-103s for about a year and they work great. I get 20-30 mbps over 60 year old wiring.

[Logboy @ May 28th 2008 11:06AM]

It's a bit faster than powerline, which didn't work for me because of my wiring. I turned to MoCA because I'm a Verizon FIOS customer and that's what they use. I'm able to stream HD content from my PC's to a set-top box in my living room and it works fine.

[Chris @ May 28th 2008 10:35AM]

MoCA is actually a great tehcnology, we've been using it @ Verizon to achieve speeds as high as 188mps from the FIOS ONT to the Router. It's good to see the technology being applied now.

[Mo @ May 28th 2008 10:36AM]

Powerline is too slow.. need grande mbps

[booticon @ May 28th 2008 10:48AM]

Hm, what about cable system that go up to 860MHz (or even 1GHz)?

[booticon @ May 28th 2008 10:49AM]

Yes that's meant to be plural (cable systems). I'm just being silly.

[Logboy @ May 28th 2008 11:07AM]

MoCA (at least my boxes) operate at 1150 mhz.

[Adam @ May 28th 2008 11:24AM]

"and being that it operates in the 800MHz to 1,500MHz range, there won't be any interference with cable TV transmissions or the like."

FAIL.

For Rogers customers living in Ontario, its a 1GHz network - this will knock out at least some services. Most likely home phone but I haven't looked up the allocations recently.

[BlowURmindBowel @ May 28th 2008 12:15PM]

Are you sure this is going to be sold in the CDM?

[Adam @ May 28th 2008 12:24PM]

No idea. But I'm sure there's gotta be a few networks in the US running at least 850.... I'm just saying; that bandwidth would have been safe 7 yrs ago but certainly not today.

[booticon @ May 28th 2008 12:38PM]

I was speaking with a couple of coworkers (cable company employee here), and from what I gathered, if this is a competent MoCA device, it'll "range" to find an unoccupied frequency. That said, if you're on a modern 860MHz/1GHz cable system, it'll probably use 1.2GHz or something around that.

[avalon2004 @ Jun 5th 2008 11:31AM]

There is something that is not clear to me here. I am a Rogers cable modem customer, so my coax cable already plugs into my cable modem and then cable modem to a router with wired and wireless ports. So I plug this new DLINK adapter into my router (I assume into one of the wired network ports), attach a coax cable to it, but where do I plug in the other end of the coax cable? The room where my cable modem and router are is already using the only cable coax outlet in the room. Am I missing something here?

[srue @ May 28th 2008 12:25PM]

I wonder if this plays well with cable modems.

[majortom1981 @ May 28th 2008 12:46PM]

Verizon fios uses this right? So how well does this work if your using verizon fios ? Also From what i understand some if not al lcablecompanies are wired for 1ghz but idon't think any actually use the extra space otherwise they would have a lot more bandwidth available. The docsis specs dont use that extra space above 850mhz.

My main question is though is does this screw up fios tv if you have it ? I am pretty sure the fios tv devices use the moca spec also but iam making sure.

[Chris @ May 28th 2008 6:07PM]

Fios Tech here, I believe it would destroy the MoCA to the SBT's and Router causing you to lose all featuers, vod, guide ect..
