The system is known as white-spaces technology and uses wireless frequencies that are in ... the band reserved for over-the-air TV broadcasts but aren't currently being used.

Netgear Offers $400 System to Combat Poor WiFi

Netgear is launching its own take on a multi-router system in order to improve WiFi across an entire home. It's not a new idea, but Netgear says its tweaks should give it a significant edge over rival setups. The logic of Netgear's Orbi and similar ... systems is that a single wireless router isn't always enough to cover an entire home adequately. Wireless signals can be weakened by passing through walls and floors, as well as being affected by metal such as pipe work. While that problem has always existed, it's become more noticeable as demand for high-bandwidth activity such as ... (view more)

Smart Devices Could Expose WiFi Passwords, or Worse

Are smart devices a security risk? Security firm Rapid 7 seems to think so. According to the researchers, a range of Internet-connected light bulbs had at least nine security flaws. While the potential consequences are hardly life or death, it could ... be a blow to the concept of smart devices in the home. Osram's Lightify range of light bulbs lets users control lighting via a smartphone or tablet app. The idea is partly to allow more precise controls, such as dimming a bulb or even changing its color, and partly to allow users to remotely access the lights.

How to: Access Windows Shares using an Android Device

Infopackets Reader Sonja S. writes: " Dear Dennis, I have a very perplexing question that has been bothering me for the last little while. For the longest time, I have been using an app called ES File Explorer for my Android smartphone, which allows ... me to connect to a shared Windows folder on my Windows PC using my WiFi connection. However, it appears that ES File Explorer now contains a bunch of bloatware and is constantly scanning my SD Card, and alerting me of programs 'requesting sensitive information'.

Can Christmas Tree Lights Degrade Wifi Signal?

Can Christmas tree lights degrade a WiFi signal? A British government agency suggests exactly that, but tech experts say it's unlikely to have a noticeable effect. The claim came in a press release for a new app to check WiFi quality. Ofcom, which ... is roughly equivalent to the Federal Communications Commission, noted that WiFi problems "could be down to something as simple as interference from other electronic devices, such as a microwave oven, baby monitor, a lamp - or even Christmas fairy lights."

Contractors at a convention center have been fined $718,000 for blocking visitors from using their own mobile data services. Meanwhile the Hilton chain has been fined $25,000 for obstructing an investigation into similar claims.

Facebook Alters News Feed Depending on Your Connection

Facebook is to tweak the way it selects and displays content in user news feeds. The idea is to make life easier for users on slow, inconsistent, or wireless Internet connections. Part of the changes affect how the content will be shown; for ... example, users on a slow connection will see more text-based content such as status updates, rather than showing more videos. There will also be a change affecting how media content is downloaded as a priority. Facebook has already switched to an image format known as Progressive JPEG that displays low quality images first, then gradually downloads into a ... (view more)
