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

Reddit's 'Explain Like I'm Five' videos star real 5-year-olds

Some subjects, like communism, zippers, and our long absence from the moon, can be a little hard to explain. That's when people turn to "Explain Like I'm Five," a Reddit group dedicated to breaking complex ideas down into understandable terms. While the group has been geared for adult readers, it has now morphed into a video series featuring real 5-year-olds.

The YouTube series kicks off with three entries. The topics covered are Syria, existentialism, and the stock market. If you can make a group of bored 5-year-olds understand these topics, you should be good to go for most adults, too.… Read more

I'm Dong Ngo, and these are my personal Wi-Fi routers

Being the person in charge of the Networking category, I've received many e-mails asking what my current personal router is, and how often I change it.

Even though I've worked with many routers -- in fact, I have reviewed most of the existing Wi-Fi routers on the U.S. market -- I don't change my home router very often. This is mostly because programing a router can be a tedious task, and I use a lot of different applications and services with many clients, all of which require different settings in the router's firmware.

That said, since the Wireless-N (802.11n) standard was introduced in 2007, I've used just about five Wi-Fi routers. Most of them them have served me very well over the years and I still have them all, except for one that was broken during a move.

The following is the list of those routers and how they've worked out for me.… Read more

IBM imagines a computer that smells your illness

For the past several years, IBM's research arm has been making predictions about emerging technologies that will change our lives over the next five years. Dubbed "5 in 5," the annual year-end list has already accurately predicted the rise of now-familiar cultural touchstones like Siri, as well as our reliance on smartphones for everything, and real-time speech translation.

This year, IBM has taken a more in-your-face approach to predicting the future of innovation, by specifically focusing on, well, the face and the five senses that make their home there (and yes, hands and everywhere else in the case of touch).… Read more

Apple: Top 5 events from 2012

Apple spent 2012 much like it did the year before: relentlessly pushing out new products. But that's nothing new.

Five key news events marked Apple's 2012, from products to company controversy.

Editor's note: This is the first in a series of stories chronicling the top five events during 2012 for a handful of major technology companies, and technology categories. In the … Read more

The 404 1,163: Where we just can't be friends (podcast)

Find a stick to bite down on during today's show, because we're learning more than we ever wanted about the band Nickelback -- how they became Internet pariahs, why they've sold 50 million records, and the stomach-churning origin of their name.

We'll also review a new documentary about disappearing glaciers and climate control, question the value of Internet ads and the new "four second rule," and prove that the new flagship Apple store in Palo Alto, Calif., is just too darn loud.… Read more

Among the top election quants, Nate Silver reigns supreme

While there's already been whole swimming pools of ink devoted to the Election Day prediction performance of polling aggregators like FiveThirtyEight blogger Nate Silver, CNET is ready to hand out one more round of kudos to the king of the quants.

By now, anyone following the presidential election knows that Silver successfully predicted the winner in the race between President Barack Obama and former Massachusetts Gov. Mitt Romney in all 50 states. That performance was one for the ages, earning him worldwide admiration and validating a polling aggregation model that had drawn mockery and ire from many pundits.

But … Read more

Obama's win a big vindication for Nate Silver, king of the quants

In the end, big data won.

Not the presidential election -- although there's no doubt that President Obama's victory tonight was aided by a sophisticated understanding of the American electorate born of years of analysis of voting trends and demographic shifts.

No, big data -- and its patron saint, Nate Silver -- won the battle to predict the outcome of the contest between Obama and former Massachusetts Gov. Mitt Romney. Where breathless pundits brandishing equivocating polls shouted from the rooftops over the last few weeks that the race for the White House was a "tossup," or &… Read more

Top five budget routers that won't disappoint

I admit it, I have a problem. I am a fan of fast networking products and often feel uneasy if what I have isn't the latest and greatest. That hasn't changed at all, despite the fact that over the years, I have realized that the latest and greatest is generally way more than I need.

The truth of the matter is, for most homes (and even certain types of small offices), all you need is a stable Wireless-N Wi-Fi router. This is because the main purpose of the router is often just to share the Internet connection and some network resources, such as printers and documents. Since the Internet speed generally caps at much lower amount than Wireless-N's speed, it won't get faster if you upgrade the router to the latest and greatest. On top of that, the majority of wireless hardware clients, such as tablets, smartphones, laptops, support Wireless-N (802.11n) or the slower Wireless-G (802.11g) standards. Since the speed of a network connection is determined by the slowest speed of any party involved, a lot of time having a superfast router doesn't help with the speed of the local LAN, either.

That said, if you just want a simple home network to share the Internet and data files, the following routers will more than get the job done. The best part is that none of them costs you more than $80.… Read more
