How MIMO Works MIMO-based Wi-Fi routers use the same network protocols that conventional (single-antenna, non-MIMO) routers do. A MIMO router achieves higher performance by aggressively transmitting and receiving data across a Wi-Fi link. It organizes the network traffic that flows between Wi-Fi clients and the router into individual streams, transmits the streams in parallel, and enables the receiving device to re-assemble (reconstitute) the streams into single messages. MIMO Technology in Wi-Fi Networks Wi-Fi incorporated MIMO technology as a standard beginning with 802....

Unlike most port numbers, port 0 is a reserved port in TCP/IP networking, meaning that it should not be used in TCP or UDP messages. Network ports in TCP and UDP range from number zero up to 65535. Port numbers in the range between zero and 1023 are defined as non-ephemeral ports, system ports, or well-known ports. The Internet Assigned Numbers Authority (IANA) maintains an official listing of the intended usage of these port numbers on the internet, and system port 0 is not to be used....

What Is 10.0.0.1? 10.0.0.1 is more commonly seen in business computer networks than in home networks where routers normally use addresses in the 192.168.x.x series instead, such as 192.168.1.1 or 192.168.0.1. However, at-home devices might still be assigned the 10.0.0.1 IP address, and it works just like any other. If a client device has an IP address in the 10.0.0.x range, for example, 10.0.0.2, the router is using a similar IP address, most likely 10....

Zoom has become a household name in a matter of just a few months, with the world turning to its video conferencing platform due to the pandemic severely limiting in-person meetings. However, an FTC complaint alleged that Zoom “engaged in a series of deceptive and unfair practices that undermined the security of its users.” This followed scrutiny from security experts earlier this year, who found the platform was not using end-to-end encryption despite marketing claims....

The M1 Macs can run any iPhone or iPad app—you just install it from the Mac App Store. The catch is that the developer can opt out, and make its app unavailable. Until now, you could work around this limit using third-party tools to download your legitimately purchased apps. Now, Apple has shut this loophole down. Is this a good thing, or bad? “This is exactly the sort of authoritarian behavior from Apple that rubs me the wrong way,” writes music app blogger Tim Webb....

Instagram CEO Adam Mosseri recently stated that we don’t have an official iPad Instagram app because the company can’t devote the resources to it. This isn’t a hand-waving excuse, either—it turns out app development is quite complicated. Even something as seemingly straightforward as a port would still require an awful lot of work. It’s way more complicated and involved than the average user might expect. “There are more factors to consider in bringing the Instagram app over to the iPad,” said Katherine Brown, founder of Spyic, in an email interview with LIfewire....

I ditched laptops a long time ago. For years, I have used a desktop Mac with an iPad. But after setting up a friend’s M1 MacBook Air, I’m totally going all-in on the MacBook Pros whenever they arrive in the world. For quite a while, the iPad has been far superior to any MacBook, but now the Mac has caught back up. What’s more, the iPad has some limitations that may never be fixed....

If you have a TPMS light, it’s important to remember that it isn’t a replacement for regular maintenance. While a TPMS light coming on can be a great warning ahead of an impending emergency, there’s no replacement for physically checking your tires with a tire pressure gauge and topping them up as needed. What Does the TPMS Light Coming on Really Mean? When you have a car that has a TPMS, what that means is every tire has a wireless sensor inside it....

For example, beginning on January 1, Comcast began limiting households to 1.2 terabytes of data per month. Other broadband companies also are turning the data taps down for their customers. While a terabyte or more is sufficient data for many people, some users could exceed these amounts and have to pay a penalty. “Americans are paying for the lack of investment by the cable companies,” Mark Chen, the owner of Bill Smart, a company that negotiates between customers and internet providers, said in an email interview....

The Steam Deck has had much of the gaming world’s attention since Valve dropped the official news earlier this month. Now all eyes are turning back to the massive publisher following news that it would be striving to offer 30FPS as the bar for what it considers “playable” on the Steam Deck. There are some caveats to that bar, and experts say that even at 30FPS, most games should be more than playable on the Steam Deck’s smaller screen....

The other way to be zapped by a car is to inadvertently act as a ground for the ignition system, which can be painful and dangerous. The other electrical systems in most cars aren’t dangerous or capable of shocking you, with the exception of electric and hybrid vehicles. The How and Why of Automotive Static Shock When you touch a car door handle, door, or another metal surface and feel a shock, the cause is the sudden discharge of static electricity....

The fight to make Microsoft Edge the default web browser for Windows machines continues. Microsoft began to patch out the option to select a different default browser in Windows 11 earlier this month, but now it’s trying a more direct approach. Neowin has noticed that discouraging pop-up messages appear when attempting to download Chrome in Windows 11. These messages won’t prevent anyone from downloading Chrome, but they do overtly try to push Edge as the better alternative....

Researchers in Japan have created a pure and light diamond for use in quantum computing in a move that could lead to new kinds of hard drives. It’s part of an ongoing effort to use the strange effects of quantum mechanics to hold information. “Unlike our classical computers that operate on binary digits (or ‘bits’), that is, 0’s and 1’s, quantum computers use ‘qubits’ that can be in a linear combination of two states,” David Bader, a computer science professor at the New Jersey Institute of Technology who studies quantum memory, told Lifewire in an email interview....

A tight seal: According to an Apple support page, a webcam cover prevents the MacBook from closing completely, as they’re “designed to very tight tolerances.” Continuing to use a cover could result in a damaged display. Going coverless: Rather than using a cover, Apple suggests relying on the camera indicator light, which glows green when the camera is active. No green light means no active camera and your activities are safe from prying eyes....

With a new school year right around the corner, Zoom wants to make it easier for kids and parents to manage remote learning. In a blog post full of back-to-school tips, Zoom recommends trying out the new Focus Mode, which “your child’s teacher might introduce in class to help students stay attentive.” Focus Mode allows teachers to view all the video feeds from their students as usual, but students only will see their own and the teacher’s feed....
