WiFi channels 1, 6 and 11 are they the best?

Published

on

Wired connections are not affected by interference in the environment. If we throw a 30 meter Ethernet cable, the signal will always arrive stable at the destination without loss if we have a good cable. However, with the Wifi the situation is very different, and more in the band of 2.4 GHz, which is one of the most saturated today. But there are ways to make it go better.

If you live in a building, there are probably dozens of Wi-Fi networks around you. They all operate in 2.4GHz band, while some others also do it in the 5 GHz, and it may even be that one of your devices is already compatible with the new 6 GHz. However, the 2.4 GHz, being the most used, is the that more tends to saturate and generate interference.

The 2.4 GHz band in Europe operates between the 2401 and 2472MHz. Among those 71 MHz we find a total of 13 channels of 22 MHz each, which overlap each other. Each channel concentrates its maximum frequency in steps of 5 MHz, placing, for example, channel 1 at 2,412 MHz, channel 2 at 2,417 MHz, and so on until reaching 2,472 MHz of channel 13.

Why does interference occur?

As happens to any wireless signal, WiFi is likely to have interference with other WiFi signals nearby overlapping frequencies, or even from other devices that also operate on those frequencies. For example, Bluetooth devices or microwaves in the kitchen emit signals at 2.4 GHz, and a microwave can, while it is turned on, create interference in the signal of our WiFi network.

The WiFi channels overlap each other, but normally wireless networks use, by default, the channels 1, 6 or 11. We see the reason in the previous graph, where we can see that these three channels do not overlap each other. In other words, it is the number maximum channels that may be available without any overlap, since there are only 71MHz to use spectrum, and each channel occupies 22MHz.

So why don’t all routers use just those three channels in the 2.4 GHz band? Well, because there would be even more interference within the channel. There are applications for mobile phones and computers that allow you to know how saturated your environment is. For example, with Wi-Fi Analyzer for Windows 10, you can see which channels are being used by adjacent networks on 2.4 GHz in the graph, as well as which channels are using 5 GHz. Looking at the graph, in my case it would not be a bad idea to use channel 1 , which is also the one that offers the most range (no matter how small the difference).

Other programs like inSSIDer They even have recommendations on which channels to use. In fact, as soon as you open it, it effectively detects that the canal 1 is the least saturated around me, and that the performance could improve if I change it in the router. Some modern routers automatically choose the least crowded WiFi channel, but unfortunately most don’t. In addition, the program also measures WiFi usage on each channel, including nearby networks.

Therefore, it is best to always use the channels 1, 6 or 11, since they are the ones further away from each other and do not overlap. Of them, it is best to choose the one that uses fewer networks around us, and, above all, the networks that are farthest from ours, which we can see in data such as the attenuation. The closer the value is to -90dBm, the less powerful the WiFi signal that reaches our receiver will be.

In the 5 GHz there are hardly any interference problems

How much the higher the frequency than a channel is available, the more speed we can achieve. That is why it was launched 5 GHz band, with a smaller range, and with a greater number of channels, which are also broader. Thus, most people who use WiFi do so near the router, and thus do not have to overload the surroundings.

Thus, as there are more and more routers and devices using 5 GHz thanks to the higher speed they offer, these frequencies can also interfere with each other. with the band of 6GHz will help further reduce the load at the frequencies of 2.4 and 5GHz, in addition to obtaining greater speed. With 6 GHz there will be in Europe up to 3 channels of 160 MHz bandwidth, which do not overlap each other. With the 5 GHz, the channels are up to 80 MHz.

Can Microsoft Defender antivirus be disabled in Windows 11?

Published

on

microsoft defender has reached a spectacular level of maturing with windows 10. What started as a basic malware protection more serious, it has become one of the best antiviruses on the market, with the advantage that it is free, lightweight, and is already included and activated with the operating system. However, there are times that we may be interested in deactivating it, but is it possible to do it with Windows 11?

When we install a third-party antivirus, Microsoft Defender is disabled. However, there may be times when it is not deactivated properly, or there may be times when we simply want to temporarily disable the antivirus to install something that is detected as a false positive. It is also possible that, on a weak computer, Microsoft Defender consumes a lot of resources; especially when booting the system. There are lighter options, or if we don’t have the internet connected device, we may not even need the antivirus.

Windows 11 allows you to disable antivirus

In the Security section of Windows 11, luckily, we can disable many antivirus functions, including Real-time Protection, which is the one that usually causes problems when it comes to detecting false positives in files that we know are safe. This protection can only temporarily deactivate, but the rest of the protection modules can be permanently disabled.

So, effectively, we can temporarily disable the protection in Windows. To do this, we go to Settings in Windows 11, and there we enter the Privacy security tab. In there, let’s windows security. Once there, click on the option that says Antivirus and threat protection. In there, we just have to go to the part of managing the configuration of Real-time protection, and disable it.

It can also be permanently disabled

This deactivation is temporary, so if we want to deactivate it completely, we will have to go to the Local Group Policy Editor. To go to this section, it is necessary to disable the function of Tamper Protection within the same section where real-time protection is temporarily disabled.

To do this, we look for theLocal Group Policy Editor«, or gpedit.msc. In there, let’s Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus. Once we get there, we look for the option «Disable Microsoft Defender Antivirus«. We double click, and we give Enabled. Now we just have to restart, and we will have the Windows 10 antivirus permanently disabled.

These are the best options we have for disable Microsoft Defender in Windows 11. Another option is to use programs like Defender Control or Configure Defender. This type of program allows you to manage a multitude of settings directly from the program and with a couple of clicks without having to navigate through the system settings.

These are the most realistic artificial voices of the moment

Published

on

We are used to hearing computer generated voices on different devices. In smart assistants, in gadgets, in ebook readers, on websites…. these voices are more and more present, but they continue to feel artificial, something that will cease to be so in a few years.

The fact is that there are already artificial intelligence engines capable of creating voice systems that are extremely natural, and today I will show you where to listen to them.

Is about vocalora.com, a web project that uses one of the world’s most sophisticated speech engines to simulate the voice of 5 different English accents, using 18 different voices in the process.

We can paste a text (in English) and select the desired voice from all the available ones. Once done, we will click on the Read Text button that appears on the right. If during the reading process we put a different voice, both will be heard at the same time.

Both male and female voices and children’s voices are available, and the result is so impressive that it is difficult to understand how our vacuum cleaner continues to speak with an 80’s movie voice.

We can try vocalora for free, but if we need readings of several hours, we will have to go through the premium subscription (about 20 dollars per month).

At the moment there are no projects with the same quality in Spanish, at least not on a website of these characteristics, available to the general public, although it is a sector that is advancing a lot, so it will not be long before we have something like this soon in our language.
