WiFi’s tougher WPA3 security is ready

WiFi security is finally getting an upgrade after 14 years. The Wi-Fi Alliance has officially launched WPA3, the next-generation standard that promises to tackle many of the vulnerabilities that have persisted in wireless networking. Most notably, it brings individualized data encryption that should protect your data against eavesdropping from within the WiFi network. You’ll also get tougher password-based sign-ins through Simultaneous Authentication of Equals, a key establishment protocol that reduces the chances of someone guessing your password — even if it’s lousy.

How to Keep Your Home Wi-Fi Safe From Hackers

You probably don’t give it much thought, but your router is one of the most important gadgets in your home—without it there’s no wi-fi for your laptops, your phones, and all the other web-connected devices you’ve got set up.

This Wireless Drive Puts Your Files in a Tiny, Private Cloud

WE’RE THOROUGHLY CHILDREN of the cloud these days, and portable hard drives have come to feel as quaint as cassettes.

But the cloud is a rented storage unit, not your own attic, and there’s something comforting about having your own data on a physical external drive. There are also some practicalities that come with owning a portable hard drive—especially if it’s wireless, like the new model from Western Digital.

Will Li-Fi Replace Wi-Fi?

If Harald Haas is right, in just a few years we’ll all be getting internet through our lightbulbs.

Haas, a professor of mobile communications at the University of Edinburgh in Scotland, has been championing the idea that data can be transmitted through LED lightbulbs for years. Now, he has created a working model of a “Li-Fi” system.

Microsoft will deliver low-cost broadband to 500,000 rural Indian villages

A major partnership with Google putting free Wi-Fi in 400 train stations wasn’t the only major network news coming from India today. The Indian government also announced on Monday that it will pair with Microsoft to bring low-cost broadband connectivity to half a million villages throughout the subcontinent. That should help at least some of the estimated 4 million people that go without internet connectivity every year.

Screw Wearables—Now Wi-Fi Will Monitor Your Body

The business of tracking your health with smartwatches or fitness trackers is oppressively hardware-heavy—all those wires, charging docks, and batteries. But that’s poised to change. Soon, it might be the space around you that do the monitoring.
