Question
Hi,
I recently read a review of a product I had no idea existed. Apparently the two unit combo plugs into an electrical outlet and the other into the computer, and you can get online.  So I want to understand for sure--if I have an ethernet card in my computer, I can get online without a subscription to any service?

Answer
Art,
Power-line networking is based on the simple concept of "no new wires". Power-line Ethernet adapters use the existing electrical power lines in your home and office to build a computer network. Consider this, almost every home and office has multiple power outlets in every room but in order to network these rooms you'll need to either setup a wireless network or shell out some big bucks to have network cabling installed. So if setting up a wireless network is not a feasible option, power-line networking is the way to go.

A few years ago the question was asked "why can't we just use the pre-existing electrical wiring as a data transport media?" Now you can. This type of networking protocol does not allow you to access the internet by simply plugging an Ethernet cable from your computer to your wall socket. Instead, you can plug your cable or DSL modem into one of the socket adapters and provide internet and media access to your entire house rather easily. Also, these products do not interfere with your existing electrical equipment or home automation devices because they operate on a completely different AC frequency.

Tests have shown that while power-line networking is not as fast as a traditional Ethernet network, it provides a simple & cost effective solution for networking a home or small office. In my opinion, wireless networking should be your first choice if you don't currently have Ethernet infrastructure.

Hope this helps!
