为什么不早告诉我系列   二


某一天，我拿着钻头在确定不会砸开水管电线之后从楼上开始往楼下打洞，目的只是为了在楼下增加一个ethernet接口，因为wifi无法满足录影传输的需求。工程是艰巨的。打洞才是万里长征走完的第一步。之后，要把长长的ethernet缆线从楼上送到楼下，再从楼下的窄眼中引出，是一件说来容易做来难的差事。

工程进行到一半，朋友打电话聊天，我告知我现在工程之浩大，朋友一顿，问我有没有听说过有这么一件神物，可以让家中电线传输因特网流？

＂还听说过用自来水管道传输因特网呢！谷歌有一次愚人节的搞笑新闻上说用下水道传输因特网。只是，创意是有，但真有这样的东东卖吗？＂

＂早就有了。＂

原来，真有这个神物。把它一头插入路由器的因特网接口，一头插入电源插座。这样你的电源线就在传输因特网流了。而且，你可以用密码保护你的因特网，所以它也是安全的。

怎样让这流动的互联网为我所用呢？你需要一个adatptor，一般是跟原件捆绑售出的。你可以在家里加上任意数目的啊adaptors。你把adaptor的一端插入墙上的插座，adaptor上的ethernet接口这时就应该流淌着这鲜活跃动、呼之欲出的互联网了。把你电脑上的ethernet缆线插入adator上的ethernet接口，你在家里的任何地方都能上网了。如果把你无线路由器插上，家里可以用上第二个wifi，大大延伸wifi的可达至的范围。

因为wifi不够稳定，又因为我们有些电器只有ethernet接口，所以这个神物真的很有用。

几天后，我的一位美国同事正在干着跟我一样楼上楼下打孔穿缆线的＂蠢事＂，我立即叫停，跟他讲了这个东东。可是讲了半天他好像还没大懂，最后他恳求我写一个详细的step
by step 的说明书，说隔天中饭的感谢。我说中饭就免了，但我会尽快写出来，所以就有了下面英文版的神器详解。我就懒一下,再加上最近较忙没有时间，就没翻成中文照贴如下：（如需翻译，请在评论里言语一声）

Think running cables through existing walls? Do NOT. Try powerline network adapter

Are you thinking about running cables through existing walls, like I did it before? Now with
new technologies like ethernet through power outlet, you don’t have to spend your time,
money and sweat to mess around your walls and cables. You have an alternative that work much better, and best of all, no need to run your cables through the existing walls, no hole-drillings, and you actually save money, time and your energy for other things at home.

Becasue you already have wires that run through your house almost everywhere. I am talking about your electrical wires. Why not re-use it and take advantage of the new technogies that can run ethernet via your power lines?

I have tried to be running cables through existing walls, or using WIFI extenders to try to extend the coverage of WIFI connections or make WIFI connections stable. However, so far I think the best way is to run ethernet through power outlets. It is almost effortless to do, plus, it definitely make your internet connections much more stable than WIFI extenders.

So here it goes, naturally, what is the best ethernet through power outlet kit to buy?

What is powerline networking?

First, what is power networking?

Power networking technology is built on top of HomePlug standards to connect computers via power line, or make internet available through existing power lines.

The major benefit of powerline networking is that users can quickily build a network using existing electrical wiring as the communication channel. So no need to drill holes in floors, walls or ceilings to route new wiring and,therefore, this way of building a computer network is fast and inexpensive.

Here is a great video as a crash course on powerline networking:

Powerline networking review

If you are looking for a Best Powerline Networking Kit, I have reviewed a bunch of different brands and styles.  The following kits are some of the most popular ones online.

Our criteria for selecting the best powerline networking kit are:

• Look for the latest and fastest version of the Homeplug standard, which is AV2.
• A Gigabit Ethernet port is another must-have.
  

The speed of AV2 adapters with gigabit Ethernet ports will be much, much better than previous generations.

ZyXel Homeplug AV2 Gigabit Powerline Adapter Starter Kit (PLA5206KIT)

The ZyXel Homeplug AV2 Gigabit Powerline Adapter Starter Kit is currently the fastest to extend your network to a corner in your home or office where your Wi-Fi signal can’t reach.

I’d have to give the nod to Zyxel for its performance under lightweight loads as well as its AC line-conditioning capability.

ZyXel Homeplug AV2 Gigabit Powerline Adapter Starter Kit is the fastest in most of our tests, and they’re the only AV2 adapters with an AC outlet passthrough, so you can plug your other gadgets into the pass-through outlets in each adapter.

The drawback is that it’s more expensive compared to the other kits. It also is very much bulky and blocks the third or grounding prong of the outlet above.  and the Ethernet cordscoming with the kit is too short short, which is only 46-inch long.

Product: The ZyXel Homeplug AV2 Gigabit Powerline Adapter Starter Kit

Price:  about $149.95 (retail)

Where to Buy with the Best Price: Amazon.com
Product Dimensions: 7 x 4 x 6 inches ; 12.8 ounces
Shipping Weight: 14.4 ounces
Guarantee: 2 Year Full Warranty
My Rating: 9.5 out of 10

Update: The newer version just came out so you may consider buying the newest version with much faster speed: ZyXEL AV1200 Powerline MIMO Adapter Starter Kit (PLA5405KIT)

TP-Link AV600 Powerline Adapter Kit: TP-LINK TL-PA4010KIT AV500 Nano Powerline Adapter Starter Kit, up to 500Mbps

If the price is a big concern to you, the top pick above becomes unavailable, or if your house/office only has two-prong outlets, then the TP-Link AV600 Powerline Adapter Kit is the best option. The TP-Link kit was faster than the ZyXEL in some of the tests. It is less bulky, and comes with longer Ethernet cables.

At the time of this writing, the TP-Link kit is the No. 1 best seller in Amazon in this category.

The drawback is, the TP-Link was slower overall and it doesn’t have AC outlet passthrough.

Where to Buy with the Best Price: Amazon.com

Usage Tips：

• Do not plug powerline kit into a power strip or surge protector, which can filter out the signals your powerline kit uses.
• Be sure to sync your adapters for encryption. Powerline adapters should have encryption to secure your powerline network from neighbors who share electrical wiring. LED status indicators are also important. Most powerline adapters have both.
