除了很多的電話線以外，就是電源線了 再來就是有幾個壁座，我不知道名稱，就是完全沒有插座或是電話孔的座 還沒有挖開來看，因為我挖了半天打不開，沒有帶工具挖得手很痛。 下次去再拍一些建商佈線的照片，我認為弄得很隨便，也沒有預留網路的孔。 |

上個星期訂了一組 ZyXEL合勤 (PLA-4225) 後再家裡測試，卻發現一個很奇怪的現象
我家有兩個電錶，竟然只有一段電線不能通，而這一段電線有經過兩個 NFC 這一段不能通應該算是正常的 不正常的是我爸口中說的不同電表的區域，竟然也可以通 附上在我家的測試結果 PLC 測試 Server 端：windows xp sp3 Client 端：Mac OS X 10.8.2 下面說的 local 是指網路訊號來源的哪一台，remote 是目的地也就是輸出端

sec 208 MBytes 14.6 Mbits/sec 這是我第一次使用電力線網路，覺得很好用，雖然平均 14.6 Mbits 速度不是很理想但是基本的上網已經夠用了。 在測試的過程中，我得到一個結論：電力線設備越接近越好 在書房的分享器是 RouterBoard 493G，在我家很好用，但是環境不一樣竟然差這麼多 另一個分享器是 RouterBoard 751G-2HnD 放在客廳，這個分享器的位置很重要，因為分享器支援 11n，在方圓十公尺內沒有干擾的情況下跑 50M 以上是完全沒有問題的，所以瓶頸就是卡在電力線設備。 這兩個電力線設備越接近越好，越靠近可以讓local 和 remote之間的速度越快，因為是在室內而且是平面，剩下的就讓 Wi-Fi去解決距離的問題 不過很可惜的是當我自己在測試的時候，上面的4，5，6測試，竟然沒辦法超過100Mbits的速度，這能是線路老舊的關係嗎？ 另一個缺點，對其他人可能不算是缺點，那就是他只支援 110V |

該買Netgear XAV 5004 買台灣產品 只有被薛而已 最新已到HomePlug AV® IEEE® 1901規範 |
用網路電力線,只要遵守一個準則就好...
千萬不要使用延長線(排插) , 只能夠直接插在牆壁的插座上 ,這樣傳輸品質就可以比較好!! |

那時候也想找 netgear 的產品，但是台灣找不到啊 引用:
我的確是插在牆壁上面，但是距離越遠就越差，而且差得很多 |

請問你是否使用主機板內建的網路卡? 如果是 , 看看你手邊有無intel晶片的網路卡 拿來使用看看,是否可以改善距離的傳輸問題 !! |

根據我以前使用站上小梅在賣的14M產品經驗，電力線產品實際頻寬只能到標示值的1/4很正常， 雖說當時又有冷氣，線路上又接一台110V的冷氣，但還是可以穩定跑3M。 網路上隨手找的 測試一 測試二 都差不多撞牆在 1/4 的部分。 所以 500M 的新產品也差不多撞牆在 130M 左右，跑不上 100M 其實不會太誇張。 |
