New 'LiFi' Gets 8 Gigabit Speed; Faster than WiFi, 5G

Light could be the key to solving one of the big problems of faster mobile Internet. But the technology, which uses spotlights to send out signals, has some limited range of uses. The technology developed by pureLiFi works on a simple principle: ... rather than using radio waves to transmit data (as does WiFi), it uses light waves. A demo of the system uses ceiling spotlights which blast out light in a cone shape. To the human eye it looks like an ordinary constant light supply. In fact it's actually flickering at incredibly high speeds to create a pattern. 5G Signals Hurt By Walls A plug-in ' ... (view more)

How to: Use a Firewall to Block Full Screen Ads on Android

Infopackets Reader Steve G. writes: " Dear Dennis, Thank you so much for your article on How to Disable Full Screen Popup Ads in Android ! Lately I have been inundated with full screen ads appearing on my smartphone and I have no idea where they are ... coming from. I tried your suggestion in the article, which says to wait for the full screen ad to appear, then press the app button on my phone to see where the ad is coming from. The problem is that these full screen ads don't have a title, so unfortunately I can't tell where the ad is coming from. You also suggested using a firewall but I am not ... (view more)

Explained: Absolute Best way to Limit Data on Android

Infopackets Reader Sam G. writes: " Dear Dennis, I work from home and also own an Android smartphone, which I use to communicate (via text messages) with friends and family. Because I am home all the time, I use WiFi on my phone instead of data. ... Therefore, I purchased a very cheap 'pay as you go' data plan for when I'm away from the office. The problem is that my data is being eaten away by apps on my phone whenever I'm on the go. I have tried disabling 'background data' on my Android phone to limit which apps can use data, but this is incredibly time consuming because each data permission is ... (view more)

Several Google devices such as the Google Home and Chromecast appear to be causing temporary WiFi outages on home routers.

Originally it appeared ... the problem was specifically restricted to one gadget, the Google Home Max, and affected only "Archer" brand routers. However, later reports have identified the problem in other models of the Google Home smart speaker, along with the Chromecast range that 'casts' Internet audio and video to a television set.

New Wi-Fi Crack can Intercept Your Data: What You Need to Know

One of the key security protections in WiFi has a serious vulnerability, a researcher has revealed. The exploit has to do with the protocol "WPA2" - currently considered the most secure protocol commonly used on WiFi routers and hotspots. Here's ... what you need to know about the WPA2 exploit. What's the problem and what does it affect? Security researcher Mathy Vanhoef has published a demonstration for what he's called "KRACKs," short for key reinstallation attacks.

Microsoft to use TV Airwaves for Internet 'Super WiFi'

Microsoft wants to use unused TV frequencies to provide Internet service in rural areas. It believes its size could help bring down the costs of the technology. 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. While Microsoft plans to use some of these frequencies, it wants the government to reserve at least three frequencies in each local area for use with the technology.

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. For example, if a home owner is ... (view more)

How to Fix: No WiFi After Windows 10 Upgrade

Infopackets Reader 'Sisi' writes: " Dear Dennis, After I upgraded to Windows 10, I can no longer connect to my wireless network. However, when I connect my laptop to my router using a ethernet cable, it works fine. How can I get my wireless network ... to work again? " My response: There's a lot of reasons that the WiFi won't work after upgrading to Windows 10. The top two reasons are that the driver for your wireless network adapter needs to be updated, or it's possible that Windows 10 does not support your wireless adapter. With that said, I'll describe a systematic approach to resolving this ... (view more)
