wifi and mesh routers

Wi-Fi router and Mesh router : What’s the difference?

More and more devices are now wireless and work thanks to your Wi-Fi network. It is therefore more important than ever that this network works properly and covers your entire home.

Even if routers provided by ISP have made great progress in this area, it must be said that they are still light years away from what specialized equipment can offer. Your ISP’s router may be sufficient if you have a small apartment or a medium sized house but as soon as the surface to be covered is too large or the walls are too thick you will only find yourself with a dead space where your house is not covered by Wi-Fi.

Choose a dedicated wireless router

There are a multitude of routeur wifi devices available from almost all network equipment manufacturers and in a very wide price range.

Using such equipment can be justified by the fact that the Wi-Fi range of your ISP’s router is restricted. Or if you have special needs. For example, some routers are specialized in gaming, others are more for experienced users.

New wireless routers are coming out much faster than the ISP’s routers evolved, allowing them to be at the top of current technology and standards. That is partly because ISP cannot afford their routers / modem to have a high production cost or to rent them at a high cost.

While manufacturers of wireless routers do not have this constraint, if they want to release a 600€ router they can do it (and it happens). Dedicated routers therefore generally have much better quality parts, and can afford to have better components like more antennas with better range for example.

But the wireless may be in your living room, your bedroom or your kitchen, it cannot emit from several places at the same time.

In some cases, in very large houses, or with walls that prevent waves from spreading, a dedicated wireless router may not be enough! You can buy the most beautiful, the most expensive, if your old house spreads over 300sqm over 3 floors, the rooms located at the top will have no signal or it will be very bad. (Imagine that the router is on the ground floor)

Solid home setup

Choose a mesh system

Manufacturers became aware of this, and thought that instead of providing extremely powerful equipment, it might be a good idea to provide something more modest, but something that is divided into several entities.

This is how the mesh system was born, and it is very fashionable at the moment, because it responds perfectly to this coverage issue.

A mesh system is therefore several devices (2, 3, 5, 10…), which will be spread throughout your home. Each has its own coverage, but all have the same Wi-Fi name (SSID). So when you reach the end of one’s coverage, the other takes over.

Of course, the coverage of one of these devices is not as good as that of a high-end dedicated Wi-Fi router, but the number makes the difference! The different satellites discuss among themselves to determine together a whole lot of things, such as on which terminal you should be connected to have the best speed, with which band, 2.4 Ghz or 5 Ghz?

They are not only simple repeaters, which reproduce the wifi network of your router at different places in your home. In the case of mesh systems, all devices are identical and produce a unified and intelligent wireless network throughout the house.

The differences

The wireless router is no better or worse than the mesh system, and the reverse is also true. Everything will actually depend on your needs.

The surface area and constitution of your house is obviously a very important point to take into account, but not the only one. Mesh systems are also very simple to set up, but on the other hand, they offer less functionality than a router.

And of course, a router may be more suitable for those who need a lot of features.

In terms of pricing, it’s about the same, if you consider a mid-range/high-range router model and a good mesh system (at least three units). So it is really a matter of how you will use the device, the size of your home, and your level of knowledge.

If you need a wireless network in a large house, you don’t know much about networking and your needs are just to access the Internet, then a mesh system is the right choice.

If you need hardware with QoS, establish static routes, redirect ports, do parental control etc. and you know how to do all this, the wireless router will probably be a better choice, otherwise you will be limited by the mesh system.

fiber vs adsl

Fiber or ADSL? Which technology is better?

Why is fiber faster than ADSL? And above all, what about choosing between fiber or ADSL when you have a choice?

The answers may not be obvious, and we explain why below.

Fiber or ADSL: a story of throughput above all

We could spend hours explaining technically what makes ADSL different from the fiber. But the easiest way to find out which fiber or ADSL is the best is to launch an Internet speed test. The speed exceeds 110 Mb/s on a fiber connection, its lower limit, i.e., a download speed of about 12.5 Mb/s. A download can go up to 1 Gb/s (or 125 MB/s in the download).

On the ADSL side, it all depends on your location. With luck, you can get a maximum of around 80 Mb/s (or 10 Mb/s in the download), because its line must be eligible for VDSL2 technology and therefore be close (less than 3.5 km) to a DSLAM (among other constraints). The user is content with a “simple” ADSL connection without VDSL technology with a maximum speed of 20 Mb/s (or 2.5 Mb/s in the download), which is now considered very weak.

What is the advantage of fiber over ADSL?

Attenuation is a defect that does not concern the fiber – or much less – since the signal strength is reflected on a glass or plastic surface inside a cable. The attenuation is almost non-existent and, above all, the data transmission speed is much faster.

The advantage of fiber over ADSL is, of course, its speed, wherever you are. However, it has one major flaw today: it requires the line to be built to the user’s home (this is called FTTH fiber, or Fiber to the Home). In other words, it is necessary for a technician to come to your home to drill through your walls or floors and physically pull it to your Internet box. It is not always possible or, at least, not still possible quickly.

Is it better to use ADSL or FTTLA fiber?

But regarding the download, it is often much faster (up to 10 or 20 times) than a traditional ADSL line. While waiting for very high-speed connections to become widespread throughout France, it very often happens that different operators only offer ADSL or FTTLA fiber offers, without any other alternative. In this case, there is no hesitation, regarding throughput, it is the FTTLA fiber that should be used. The subscription sometimes costs a few more euros, but it is to have a much higher performance.

Fortnitevulnerability

Epic Games: millions of Fortnite players exposed to a vulnerability

A flaw in Fortnite that was discovered by researchers from a security solutions provider allowed hackers to take control of a player’s account, and to access his confidential data. Corrected since then by Epic Games, this breach made it possible to use the recorded credit card and listen to the games without the players’ knowledge.

Thanks to its team of researchers, security systems publisher Check Point Software Technologies discovered a flaw in the Fortnite video game that potentially affected all registered accounts, 200 million players worldwide. The main version of the game, called Fortnite Battle Royale, consists of a player-to-player battle, with games involving up to 100 players at a time, organized in teams of two or four, or solo. They must scan the map for weapons, objects, and resources. The last team still alive wins the game.

Players can buy V-Bucks, the virtual money of the game, by spending real cash after recording their credit card information, and most often, their parents’ credit card information. These purchases offer no strategic advantage and are mainly used to obtain cosmetic improvements. Despite this, accounts can be resold on specific sites for several hundred dollars, making them a target of choice for hackers. The most common scams use fake sites that promise players free or discounted V-Bucks, encouraging them to identify themselves and therefore give the website their password.

Hacking with a single click

The discovery of the Israeli research team is much more sophisticated and consists of a flaw in the identification through another sub-domain of the publisher Epic Games. The website, dedicated to the results of Unreal Tournament 2004, contained a SQL vulnerability. The team took advantage of this opportunity to steal the user’s OAuth identification token, which allows them to identify themselves with a third-party account, such as Facebook, Xbox Live, Nintendo, Google or PlayStation Network. This token is sufficient to access the player’s account on the site. The attack takes the form of a link, for example by promising promotional V-Bucks. Just clicking on the link allows the pirate to steal the token, no further action is required.

The researchers’ demonstration shows that they were able to access the entire account and even buy virtual currency with the registered credit card. However, the intrusion is not limited to the personal information on the site. By logging into the account, a potential hacker could have followed the discussions in the game, including the audio talks. Any intruder would not only have been able to hear the player talking but also conversations from other people in the background, near the microphone.

The vulnerability is already fixed

Even if fixed with a patch, the fact remains that this breach, not exploited in its current state since discovered by researchers, could encourage pirates to dig deeper into the game’s protections to exploit other vulnerabilities. And this time, it is not sure that the publisher will be informed.

Benefits of Using Cannabis Vaporizers

the gopro karma

Test Karma Gopro Drone

With Karma, US sports camera manufacturer GoPro wants to compete with Chinese DJI’s Phantom and Mavic. We put it to the test.
Go Pro relaunches its Karma drone gopro. After a reminder of the first version for a recurring battery problem, the American company hopes this time to get back on the right foot and finally enter the race of video drones, where DJI reigns almost as master. We tested it, here’s the verdict.

We loved

pack and transport bagStabilization. The three-axis stabilization system fulfills its function perfectly. The image does not move in flight, except for an inertia movement in the event of a sudden stop, which can be easily avoided by smoother steering. Note that the camera is in front of the propellers and that they are never visible in the image. A very good point.

Image quality. The model we tested is equipped with a Go Pro Hero 5 camera, which shoots in 4K at 30 frames per second. It’s accurate with a very interesting color rendering. Full HD mode is less efficient. Also missing is a 60 fps 4K mode, proposed by the Phantom 4 Pro DJI for example.

Security. Go Pro integrates automatic return with two options: return to the starting position or return to the user’s position. Both prove to be accurate. However, we did not have the opportunity to test the drone’s behavior in case of signal loss. The absence of obstacle detection can also be regretted.

The radio control. Nice effort from Go Pro. The radio control, with its roundness, is particularly well thought out, with its integrated screen and its sticks and buttons well positioned. It is very small in size. On the other hand, it is a pity that there are so many reflections under strong light.

The kit with the stabilizer “karma grip”. A good point for Go Pro, the Karma comes with a handle to adapt the camera’s stabilizer for ground shots. This is enough to amortize the price of approximately 1,300 euros when the competition chooses to sell this option separately.

We didn’t like it so much

karma in flightThe weight. With its folding arms, the Karma offers a relatively small footprint, but this advantage is quickly erased by the weight of the machine. Go Pro announces one kilo for the camera, 545 grams for the battery and 230 grams for the stabilizer, i. e. almost 1.8 kg in total, without the camera! When used, it is heavy, too heavy compared to the competition.

Reactivity. Karma is not a racetrack, a race drone. But that does not excuse the drone’s pathetic behavior in the air. In normal mode, the device does not reach 30 km/h and reacts very, very slowly. All this, of course, improves the image stabilization, but that’s less argument for the pleasure of flying. In sport mode, the drone becomes more nervous, with a top speed around 50 km/h, but suffers from a high inertia that affects the image and, above all, battery life.

DJI’s Mavic Pro – A serious contender for Gopro

Autonomy. Let’s talk about the battery! Karma offers just 20 minutes of flight time for one hour of charging. With such a large accumulator (545 g!), we had every reason to hope for something better. The total weight of the machine doesn’t help, that’s a shame.

Few intelligent modes. Go Pro does the strict minimum on this point. Three intelligent modes are available (Panorama, Cable Cam, and Orbit). No “Follow me” mode, therefore, to order the drone to follow its pilot. The modes present are tedious to use, with the need to determine the route before launching the automatic flight.

Verdict

GoPro’s adventuring into the UAV market has come up against one obstacle: not to be a quadcopter specialist. The defects of Karma only accentuate the sensation of paying high prices for a product that is not fully optimized.

snapchat is having a hard time

SNAPCHAT: New design coming soon!

Snapchat is preparing a significant update with a new interface. It is beginning to show through a few shared captures online.

Snapchat is in a difficult situation. In spite of its community, the company is struggling to break even, and competition has intensified. Worse still, Facebook did not hesitate to pick up on its functions and take over some of its peculiarities.

Evan Spiegel is well aware of the stakes involved and recently announced his intention to deploy a new version of his application at the end of the year.

Snapchat is going to get a new skin.

The latter will benefit from an entirely new interface that is both simpler and – above all – more intuitive. The idea is, of course, to make the tool accessible to the most significant world to revive growth and gain new market share.

Evan Spiegel returned to this new design during a panel discussion by presenting several visuals of this new interface.

The new Snapchat will, therefore, be entirely different from the old one and will require a separation between social content and media to simplify the use of the solution. Evan Spiegel is aware of taking a risk, but he thinks that this separation of materials will allow him to monetize the solution better.

On the one hand, the solution will always allow us to interact with our contacts and groups. On the other hand, it will present the different contents shared by the platform’s users, content displayed on an infinite grid composed of tiles, all with horizontal navigation.

In order not to lose the most frequent users, the application will always open on the camera. Snapchat will, therefore, continue to place creation at the heart of its priorities, and this is apparently a good thing, as it has also contributed to its success.

A more accessible interface to reconnect with success

To access the activity of your friends, the user will just need to scan the left panel. This page will list all the new content shared by the contacts, and it will, of course, be enough to tap on the element of its choice to display the text, image or video associated.

The right panel will show content shared by publishers, media, and the community. The Discover tab will be present, as well as for the Snap Map and the Collective Stories.

The content of this page will vary according to each user, and the tool will rely on the user’s personal preferences to bring up the most relevant elements. On the other hand, all indexed content will be systematically checked by the company’s employees before being published.

This tab will evolve in the coming months to highlight the content created by influencers and creators. The latter should, therefore, gain in visibility.

As a reminder, the new version of Snapchat will start rolling out at the beginning of December, but not everyone will be able to enjoy it at the same time. The company has opted for a progressive deployment.

Test iPhone X

Apple’s latest smartphone is not the expected revolution, but its facial recognition technology is particularly impressive.

The iPhone X, long awaited by Apple fans, is finally released. For this anniversary smartphone, released just ten years after the first iPhone in 2007, Apple wanted to mark the occasion and promised: “the biggest leap forward since the original iPhone.”

So what is this new smartphone worth: is it different from its predecessors? After a week of hands-on experience, here are the three strong points and three weak points of the iPhone X.

Three reasons to buy it

lfsbkjgfbsbfksbkqsbjxjxxxxxFirst good point: design and ergonomics. With the iPhone X, we say goodbye to the iconic design of the iPhone, which has remained virtually unchanged since its inception with its unique round button and large rectangular screen. Apple has chosen to get rid of this physical button so that the screen occupies the entire front face of the phone. Featuring two glass fronts and aluminum contours, the iPhone X looks like a small high-tech gem.

The phone is equipped with a new 5.8-inch screen – the first OLED screen that meets iPhone standards, manufactured by its competitor Samsung. This Super Retina screen displays high-precision, vivid colors, and beautiful contrast.

Previous iPhone users will have to learn new gestures to navigate in the smartphone without the Home button. But ergonomics, which has always been a high point at Apple, is very well thought out and it only takes a few minutes to get used to, for example, getting out of an application by sliding your finger upwards.

Face ID “facial recognition is the great innovation of this phone. The user’s face becomes his password: he just has to look at his screen, and it unlocks almost instantly, or to confirm a purchase with Apple Pay.

Configurable in a few seconds, this function is useful even in the dark, or when a scarf or sunglasses half mask the face. A little extra: as long as the phone detects that its owner is not watching it, it does not display its notifications in their entirety, to preserve its privacy.

Unlike Samsung’s Galaxy S8 facial recognition, which is less reliable because it is based on 2D, the Face ID system projects 30,000 invisible dots on the face of the person, to map it in 3D. It is challenging to hack into this system, even though a Vietnamese cybersecurity company said it was achieved by printing a 3D face.

The test of the iPhone X in video

Three reasons to do without it

Apple’s main selling point, which promises a “big leap forward” and aims to “pave the way for technology for the next decade,” is falling through the cracks. The iPhone X is a beautiful evolution, but not a revolution.

Whereas ten years ago, the apple company defined the essence of the smartphone itself, this new product seems to be more in line with the competition. Its onboard screen can be found on the Galaxy S8 and LG V30.

And augmented reality applications, enhanced portrait mode for photos and induction charging, presented as new features, can be found on the iPhone 8.
