Wi-Fi AC with MU-MIMO: Everything you need to know

Currently home routers with Wi-Fi AC support 3 and 4 simultaneous data streams to provide higher wireless speeds, thus if we connect a client who also supports these multiple streams, we will use all the bandwidth the router allows. However, there are many devices that incorporate only one flow such as smartphones and tablets, which makes wireless network much slower affecting faster clients. With MU-MIMO technology we will optimize the overall performance of the network.

MU-MIMO (Multi-User Multiple Input Multiple Output) is a technology that is part of the standard 802.11ac and uses beamforming technology to focus the signal on wireless clients, it is also capable of allowing simultaneous transmissions to clients.

If we have a three-stream router but we connect customers that are 1-stream, wireless network instead of working at the maximum speed provided by these 3 data streams, will work at the maximum speed that one stream provides. So far, it’s logical to think the wireless network will always run at the maximum speed that the client supports, but in this scenario we connected two other clients, the best performance will be divided among the three users connected and transferring data in the network because one will transfer information first and then the other (in series).

Enable MAC randomizer in Windows 10

This trick requires some hardware, but it is certainly interesting. It enables us to make our hardware address to be different in each wireless connection and therefore to be more difficult to trace using typical tracking wireless networks applications. Our hardware always looks different and therefore we will be more hidden in public and private networks.

The method is easy to activate. We just have to go to the network settings of Windows 10, select Wi-Fi and “advanced options“.



MSI GS40 Phantom, the maximum power at 14 inches

Recently, MSI has announced the introduction into its catalog of the new 14-inch laptop GS40 6QE Phantom, which will now be part of the G family of the brand’s laptops oriented to games. This is one of the computers with best relation size – power of the brand, and of course incorporates all the latest technologies.

Let’s start with the technical specifications. MSI has integrated a sixth generation Intel Core processor i7-6700HQ, high-end processor that perhaps is a bit oversized for games but MSI has wanted to play it safe so we won’t have any problems because of the processor performance. Along with this, the GS40 Phantom has a dedicated graphics card MSI GeForce GTX 970M (3GB DDR5 VRAM), 16GB DDR4 RAM, a 256GB SSD M.2 (SATA) and additionally a 2.5-inch 1TB mechanical hard drive.

MSI GS40 Phantom

As you can see this is a device that has more than enough in terms of technical specifications and that theoretically should be able to provide an excellent gaming experience with any current game in its 14-inch full HD resolution screen (1920 x 1080 pixels). Speaking of the screen, MSI has integrated its stealth technology to be ultra-thin, so that the size and weight of the device is quite small, and even so, thanks to its dual independent cooling system for GPU and CPU it will not suffer overheating problems.

Microsoft Surface Pro 4 Review

On October 6th we attended the event Microsoft® called ‘Windows 10 Devices’ in which, along with new terminals of the range of Lumia, presented the renewal of its Pro range of convertibles. If you’re thinking about getting one, do not miss our analysis of the Surface Pro 4, the most anticipated convertible by Microsoft®.

Microsoft Surface Pro 4

Since its birth, in early 2013, the Surface Pro family has two basic principles. First, to combine under the same manufacturer both hardware (the computer itself), and software, allowing an excellent level of optimization. The second premise, also related to the union, is to offer the best of two worlds: the portability of a tablet and the power of a laptop.


How to set default programs, file type and Library Save locations in Windows 10

When you want to use a file (either text, music, video, PDF or a website), Windows 10 searches the list of applications, files, protocols and partnerships by default to launch the right program. This list can be customized, adapting it to your favorite software.

1: Choose the default applications

When you play a video or try to read a text, Windows 10 chooses a default application depending on file type. These are the default programs, and by default Windows gives preference to its own applications. If you open a website it will do it with Microsoft Edge, and if you try to read a PDF document it will do it with PDF Viewer.


How to securely and irreversibly erase hard drive completely

To delete data from a hard drive properly, a rewriting process of all sectors is performed recursively. That is, the hard disk is completely rewritten repeatedly in a write loop, which makes the recovery of residual data to be an almost impossible task.

Erase a hard drive completely

To delete data from a mechanical hard drive, the most appropriate tool, in our opinion, is DBAN (Darik’s Boot And Nuke). You can boot it from a bootable CD, or upload it to a pendrive with Unebootin or Yumi. You can start up from it and just have to wait to be able to choose the drive or drives that you want to safely erase. If you don’t want to complicate things, the standard method without any configuration already provides high quality erasing levels.

Erase a hard drive completely

Simply select the drives that you want to delete and run the action. The standard method used is DOD Short. This method, designed years ago by the Department of Defense of the United States, uses a triple writing in each sector of the disk. First a character, its complementary character and then a definite a random character. Subsequently a check is made. It has been used for years and though some experts describe it as obsolete, it certainly is a fairly reliable method for the type of information that a home user would leave on its hard drive.

How to Configure Privacy in Windows 10

Since the release of Windows 10, there have been plenty of detractors ranting in their reviews on the collection and use of personal information that Microsoft makes with their new OS version. Some are furious and use the term ‘big brother’ and how they have gotten away with spying users. Privacy in Windows 10 is in question but in our opinion, these claims are exaggerated. Does Microsoft spy on users or is the user not properly using the settings?

The news of massive spying programs from agencies such as NSA and the alleged omission by act or the large technology companies seemingly looking the other way have triggered concerns about user privacy issues.


Checking the privacy settings after upgrading to Windows 10 Threshold 2

A portion of users are reporting that the upgrade to Windows 10 Threshold 2 resets the privacy settings by default, it reinstalls previously removed native applications, as well as file associations.

Windows 10 Threshold 2 is the first major update to the new Microsoft operating system since its launch in late July and it’s highly recommended for users because it includes improvements in all aspects. In overall performance, user interface, Cortana assistant, Edge browser, in updating its device drivers, in compatibility with applications, and also in business management and security features, as a nod to facilitate implementation and deployment of Windows 10 in companies of all sizes.
