Did you know that you could create and use a QR code to better facilitate using stronger security on your wireless network? A QR code is not in and of itself more secure than manually typing in a passcode, but if you want to use a long string of 63 characters and symbols, you would otherwise need an exceptional memory. Let's be real, who has time to remember a unique set of 63 characters? For the most part, it is not really feasible. At the same time, using a long passcode can help defend against brute-force attacks. The thing about WPA and even WPA2 is they are vulnerable to password cracking attacks, and the weaker the passcode, the easier it is crack. That's where using a QR code comes into...

Over the past few months, we have seen a spattering of Wi-Fi 6 (802.11ax) routers enter the fray, including the ASUS ROG GT-AX11000 and Netgear Nighthawk AX8, both of which we recently put to the test. There was a caveat to our testing, however—we had to benchmark them using Wi-Fi 5 (802.11ac) hardware, because at the time, Wi-Fi 6 had not yet really permeated the marketplace on the client side. That's to say, practically every modern device with Wi-Fi connectivity is sporting a Wi-Fi 5 adapter. In a sense, companies like ASUS and Netgear had put the cart before the horse. It is not that these companies are obtuse. Rather, they recognized where the market was headed and essentially got...

Every major wireless company likes to thump its chest and proclaim it is home to the best network, in terms of speed and coverage, but is there a clear winner? According to the latest USA Mobile Network Experience Report by OpenSignal, Verizon leads the way more often than not, though the results are a bit more surprising when you dig into the individual tests. OpenSignal tested wireless performance in five different categories—4G Availability, Video Experience, Download Speed Experience, Upload Speed Experience, and Latency Experience. Verizon won three of the five categories, those being 4G availability, videos, and uploads. Click to Enlarge (Source: OpenSignal) What's interesting, though,...

If you are itching to be one of the first on the block with 5G wireless connectivity, AT&T is getting ready to turn on its network in a few select cities. Unlike Verizon's 5G service, which is using proprietary technology -- at least initially -- AT&T says that its 5G network is "standards-based". At the moment, there is only one device that is certified for use on AT&T's 5G network, and that's the Nighthawk 5G Mobile Hotspot. This little device will allow your notebook, tablet, or any other Wi-Fi capable device to hop on AT&T's network and enjoy the faster data speeds and incredibly low latency. Unfortunately, AT&T isn't giving us any concrete details on how fast...

Stronger wireless security is headed to homes and businesses. That's because the Wi-Fi Alliance this week formally introduced Wi-Fi Certified WPA3, the next generation of Wi-Fi security with new capabilities to bolster personal and enterprise wireless networks. The new standard builds upon and ultimately replaces WPA2, which has seen widespread adoption over the past 10 years, enabling more robust authentication. No small upgrade, WPA3 delivers increased cryptography strength for highly sensitive data markets. There are two modes, WPA3-Personal and WPA3-Etnerprise, both of which use the latest security methods and disallow outdated legacy protocols. Both also require the use of Protected Management...

It was right around a year ago when AT&T trumpeted plans to expand its '5G Evolution' network to 20 metro areas before flipping the calendar to 2018. That number has since ballooned, with AT&T today announcing the launch of 5G Evolution connectivity in parts of 117 new markets, bringing the total number of markets served with that technology to 141. "We’re building a 5G network that will fundamentally change the way the world lives and works," said Melissa Arnoldi, president of Technology & Operations. "5G will provide a wireless experience that is faster, more responsive and more secure for our customers." It is an aggressive roll out for sure, though to be clear, 5G Evolution...

Wireless carriers have already started extolling the benefits of 5G over existing 4G LTE networks, the primary one being raw speed. 5G reckons to be much faster than 4G, which could open up a new world of possibilities on mobile. The question, how much faster will 5G actually be in real-world settings? Qualcomm has been conducting simulated tests over the past several months to answer that very question, and the results are pretty exciting. "There is a lot of interest from various stakeholders in the mobile ecosystem—cloud platform providers, application developers, device OEMs, and others—in understanding the real-world performance that 5G NR mobile networks and devices will deliver,"...

Most of us have had a love-hate relationship with wireless networking. It’s a wonderful technology when all your devices remain connected and perform well in every room of your house, but that’s not always the case. When your devices intermittently drop off or can't find a strong enough signal strength for reliable web browsing, or even if you're suffering through endless video buffering, there isn’t much you can do in that moment, but accept you’re at the mercy of your wireless router. Networking companies sought to fix that with wireless network extenders, but most of those early devices were a messy affair that required separate network names and manually selecting...

The FCC has been catching heat in its current form for making changes to existing regulations governing broadband internet access. The big change the FCC made was to eliminate the net neutrality rules that forced ISPs to treat all traffic equally, no matter the service or application. Another place where the FCC was considering a big change was with a plan that could have weakened the definition of what speed and type connection qualifies as "broadband." Thankfully, the FCC is stepping away from a new classification that would change the definition of broadband. The draft 2018 Broadband Deployment Report has now been issued by FCC Chairman Ajit Pai. The good news is that the FCC has chosen...

AT&T has positioned itself to be the first U.S. company to roll out real, honest-to-goodness mobile 5G service in a dozen markets by late 2018, the company announced today. And unlike AT&T's 5G Evolution service, which in many areas is just a rebranding of 4G LTE, what AT&T is pitching here is true 5G wireless performance that conforms to 3GPP's recently introduced 5G new radio (NR) standards. "5G will change the way we live, work and enjoy entertainment," said Melissa Arnoldi, president, AT&T Technology and Operations. "We’re moving quickly to begin deploying mobile 5G this year and start unlocking the future of connectivity for consumers and businesses. With faster speeds...

A security expert at Belgian university KU Leuven has discovered a major vulnerability in the Wi-Fi Protected Access II (WPA2) protocol that could a expose a user's wireless Internet traffic, including usernames and passwords that are entered into secure websites. The vulnerability affects most devices and several operating systems, including Android, iOS, Windows, Linux, and OpenBSD. "Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted," Marthy Vanhoef, a security expert at Belgian university KU Leuven, wrote in a detailed report (PDF) outlining the vulnerability. "This can be abused to steal sensitive information such as credit...

For all the attention that has been poured onto Android 8.0 Oreo, one thing that has kind of flown under the radar is support for Wi-Fi Passpoint. This is a technology that was introduced by the Wi-Fi Alliance back in 2012 to make bouncing from one hotspot to another a smooth and seamless transition, and it is included in Google's Android 8.0 update, which Google describes as the biggest change to the foundations of Android to date. This is a big convenience that is coming to Android. Without it, roaming a city landscape and going from one hotspot to another is an annoying affair that requires multiple logins as you go about your business. Wi-Fi Passpoint eliminates that hassle by keeping you...

Netgear has a solution to eliminate those pesky Wi-Fi dead zones in your home and to extend wireless coverage to every nook and cranny. It is called the Nighthawk X6S (model EX8000) and it is an AC3200 tri-band Wi-Fi range extender, which itself does not sound all that sexy, but there is more here than meets the eye. One thing that makes this range extender stand out from the competition is Netgear's patented FastLane3 technology. FastLane3 is a fancy marketing term Netgear came up with to describe three critical components of the Nighthawk X6S, those being tri-band Wi-Fi, a dedicated Wi-Fi link from the extender to your router, and an optimized antenna design inside the range extender. That...

It is only a matter of time before all of the major wireless carriers in the United States upgrade their wireless infrastructures to 5G, which will provide a significant boost in performance over 4G. In preparation for that day, Apple has begun testing next-generation wireless technologies so that its future iPhone models such as (potentially) the iPhone 8 will be ready for the high-speed revolution. We know this because the FCC made public an experimental license filed by Apple that gives the company permission to use a new wireless technology called millimeter wave. "Apple Inc. seeks to assess cellular link performance in direct path and multipath environments between base station transmitters...
