為什麽不早告訴我係列   二


某一天，我拿著鑽頭在確定不會砸開水管電線之後從樓上開始往樓下打洞，目的隻是為了在樓下增加一個ethernet接口，因為wifi無法滿足錄影傳輸的需求。工程是艱巨的。打洞才是萬裏長征走完的第一步。之後，要把長長的ethernet纜線從樓上送到樓下，再從樓下的窄眼中引出，是一件說來容易做來難的差事。

工程進行到一半，朋友打電話聊天，我告知我現在工程之浩大，朋友一頓，問我有沒有聽說過有這麽一件神物，可以讓家中電線傳輸因特網流？

＂還聽說過用自來水管道傳輸因特網呢！穀歌有一次愚人節的搞笑新聞上說用下水道傳輸因特網。隻是，創意是有，但真有這樣的東東賣嗎？＂

＂早就有了。＂

原來，真有這個神物。把它一頭插入路由器的因特網接口，一頭插入電源插座。這樣你的電源線就在傳輸因特網流了。而且，你可以用密碼保護你的因特網，所以它也是安全的。

怎樣讓這流動的互聯網為我所用呢？你需要一個adatptor，一般是跟原件捆綁售出的。你可以在家裏加上任意數目的啊adaptors。你把adaptor的一端插入牆上的插座，adaptor上的ethernet接口這時就應該流淌著這鮮活躍動、呼之欲出的互聯網了。把你電腦上的ethernet纜線插入adator上的ethernet接口，你在家裏的任何地方都能上網了。如果把你無線路由器插上，家裏可以用上第二個wifi，大大延伸wifi的可達至的範圍。

因為wifi不夠穩定，又因為我們有些電器隻有ethernet接口，所以這個神物真的很有用。

幾天後，我的一位美國同事正在幹著跟我一樣樓上樓下打孔穿纜線的＂蠢事＂，我立即叫停，跟他講了這個東東。可是講了半天他好像還沒大懂，最後他懇求我寫一個詳細的step
by step 的說明書，說隔天中飯的感謝。我說中飯就免了，但我會盡快寫出來，所以就有了下麵英文版的神器詳解。我就懶一下,再加上最近較忙沒有時間，就沒翻成中文照貼如下：（如需翻譯，請在評論裏言語一聲）

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.
