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

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.
