So, yeah - Ethernet does have a 10Mbit COAX option. It's was pretty useful back before switches, since you didn't need to buy a hub. It did have BNC connectors/T-adapters/Terminators, which meant if someone unplugged something the whole network went down. However, I believe the cable was 50-ohms, versus common home cable coax which is 75-ohms.

I remember trying to explain to someone why his COAX network was down when the terminator on the end had been removed. After going through the technical reasons, and getting a blank stares, I simply stated, "Your packets were leaking out all over the floor". It got the message across..]]>Apr 21st 2009 7:51AMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 8:24PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 9:21PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 9:48PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 10:13PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 21st 2009 7:20AMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 8:27PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 8:30PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/

I just pulled some CAT6 at one of our campuses because there was co-ax inplace at 10mbit and we needed 100mbit, but gigabit was preferable and at 50/router affordable too. But I guess this is more about inplace cable wiring and less about previous co-ax network installs.

p.s. 200 is 100 up and 100 down in case you're using a switch and not a hub.]]>Apr 21st 2009 1:21AMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/

It looks more expensive and doesn't offer a speed improvement over 200mbps Powerline adapters. It also wouldn't be any more convenient, there are alot more power sockets than vacant Coax ports.

I used to scoff at using such solutions in place of wi-fi, but I recently purchased a Belkin AV Powerline adapter for my parents home, which has dead spots and intermittent connections even with a long range router.

The Belkin Powerline Ethernet bridges are THE easiest networking solution I have ever used. No running cables, no network keys, no setup of any kind. Once you have one linked to your router it is literally plug and play for each additional socket. Need a ethernet port in your office? Plug in an adapter, connect your computer and your done.

No matter how you try to justify it, if you only need a hardline connection between two computers a powerline connector is always going to be easier and 99% of the time less expensive, than running an ethernet line.]]>Apr 20th 2009 10:03PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 21st 2009 12:38AMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/
I've had no luck with powerline in my house at all. seems to be wonky at best for me. panel issues or something. i never saw near the advertised speed. usually 60-80. not terrible. as I said connection would not work in all areas in my house...i tried every outlet with 1 other location.

I also have wireless issues. I'm genrally not a fan of home grade wireless devices. I use then because I'm cheap and I pay for it in the end. I would never put my main pc on a wireless connection. would you? ok for internet and email. when it comes to work stuff i want it wired. too much interference overall....too many homes around me use it. useless to push large video streams around for me on a consistent basis.

wired is better...always. running a cat 5/6 cable would be sucky. these adapters took 15 min.....maybe 15.]]>Apr 20th 2009 10:19PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 10:39PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/

The big deals are 1) >100 Mbps throughput at long distances through multiple splitters and 2) quality of service. Powerline has major problems when passing through the circuit breaker (i.e., not on the same circuit). It'll work, but not all that reliably and with significant throughput losses. It is also extremely susceptible to interference from high-draw appliances such as microwaves and the like. Wireless-N is good, but again highly susceptible to interference and, at least for me, quite erratic with regard to throughput. I also need to be very close (]]>Apr 20th 2009 10:53PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 10:56PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 10:57PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/Apr 20th 2009 11:35PMhttp://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/http://www.engadget.com/2009/04/20/d-link-finally-ships-the-dxn-221-coax-ethernet-adapter/
