Top five power-line adapters: When Wi-Fi fails you

In home networking, the fastest way -- in terms of data speed -- to connect devices together is via network cables. However, running cables properly, which involves making networking ports and connector heads, is no easy task. This is part of the reason the wireless network (Wi-Fi) has become so popular. But chances are, there's a spot in your home that the Wi-Fi signal can't reach, because of distance or thick walls. This is when a power-line connection can be a useful alternative.

Power-line adapters basically turn the electrical wiring of a home into network cables for a computer network. You need at least two power-line adapters to form the first power-line connection. The first adapter is connected to the router and the second to the Ethernet-ready device at the far end. There are some routers on the market, such as the D-Link DHP-1320, that have built-in support for power-line connectivity, meaning you can skip the first adapter. After the first connection, you just need one more adapter to add another Ethernet-ready device to the home network.

Apart from the ability to bridge the network through thick walls, power-line connections are also a lot more stable than Wi-Fi signal and have as low latency and a regular Ethernet wired connections.

Currently there are two main standards for power-line networking, HomePlug AV and Powerline AV 500. They offer speed caps of 200Mbps and 500Mbps, respectively. The following is the list of top five power-line adapters on the market. This list is sorted by the review date, starting with the most recently reviewed. It will be updated as more devices are reviewed.… Read more

Social networking on desktops may have peaked in 2012, Experian finds

Perhaps there is such a thing as too much Facebook.

In 2012, U.S. consumers on personal computers spent about 27 percent of their Internet time with social networking sites and forums, or 16 minutes for every hour, according to data from Experian Marketing Services.

Though that's an alarming finding for some, the figure, which doesn't reflect mobile browsing, is actually down 3 percentage points from the previous year. In 2011, social networking in the U.S. peaked at 30 percent of all time spent online, according to Experian.

U.S. consumers are not alone in their adjusted … Read more

Facebook reportedly wants $1 million for each video ad

Study: Anxiety and alcohol use linked to Facebook

In a quest to learn what leads some people to turn to Facebook to connect with others, doctoral student Russell Clayton of the Missouri School of Journalism found that anxiety and alcohol use seem to play a big role.

For his master's thesis, which appears in the May issue of Computers in Human Behavior, Clayton surveyed more than 225 college freshman about two emotions, anxiety and loneliness, and two behaviors, alcohol and marijuana use. He found that the students who reported both higher levels of anxiety and greater alcohol use also appeared the most emotionally connected with Facebook. Those … Read more

LED lights could become network devices, too

Today, you've got wireless networks that use radio waves and you've got optical networks that use light traveling in tiny glass fibers. Tomorrow, if Fraunhofer Institute research comes to fruition, a combination of the two could turn living-room lights into network devices.

The German applied-research lab has developed wireless networking that uses rapidly blinking LEDs to transmit data through the air. The technology can send data at speeds up to 1 gigabit per second -- and by using three colors of light, triple that data rate is possible, Fraunhofer said.

The technology could be useful in crowded, interference-prone … Read more
