What is DNS and how does it work?

DNS stands for Domain Name System. It is a system
that allows you to assign readable names to the IP addresses of devices connected to the Internet. In this way, users can access websites, online services, or network resources using easy-to-remember names, such as www.bing.com, rather than long and complex numbers, such as 204.79.197.200.

The way DNS works is based on a hierarchy of servers distributed around the world. They store and update information about names and associated IP addresses. When a user enters a domain name in his browser, the DNS system looks up the server that contains the information about that domain and returns the IP address. Thus, the browser can then establish a connection to the server hosting the requested website and display its content to the user.

How to use AdGuard’s DNS service on your Android phone

The AdGuard DNS is an alternative service to the one offered by our Internet provider or our router. In addition to performing the basic function of resolving domain names, it also filters the requests that are made to advertising and tracking servers. Preventing them from being loaded on our device. Thus, we can surf the Internet without seeing ads or being tracked by third parties.

Follow the steps below to use the AdGuard DNS service:

First step

Go to the Settings application on your Android phone.

Second step

Then go to Network & Internet>Advanced>Private DNS. You can get to this option easier and faster by typing “Private DNS” in the search box of the Settings app.

Third step

After that, once you have selected Private DNS, tap on “Private DNS provider hostname”.

Fourth step

Now, you have to enter the AdGuard DNS address:

dns.adguard.com (to block advertising and tracking).

Fifth step

Finally, click on Save and that’s it!

With these steps, you will have already activated AdGuard DNS on your Android device. And you can enjoy cleaner and safer browsing. Of course, keep in mind that this method only works if you have Android 9 or higher, and that it may not be compatible with some public or private WiFi networks that require specific configuration.

Alternatively, you can activate this DNS from a more intuitive interface with the AdGuard app that you can download from Google Play.

Google Play | AdGuard for Android

Is it safe to use the AdGuard DNS service?

The dns.adguard.com is a public DNS service that protects against tracking, phishing, and malware. According to its website, dns.adguard.com uses encryption and does not keep any logs of user queries. However, as with any DNS service, there is a risk of bugs, unwanted failures, delays, or crashes. It is therefore recommended to
use dns.adguard.com with caution and verify its reliability and performance before relying on it for browsing. Thank you for reading us. Goodbye!

Blocking the permanent mobile data connection

Wireless connections are an essential part of smartphones, especially after the progressive popularization of apps connected at all times. Android searches for a tower to connect to, tries to locate known WiFi networks and, on top of that, performs both tasks constantly and by default. Restricting this operation will have positive effects on battery saving without wasting more than a few minutes each day.

Increasing battery life is possible with two hidden settings on your Android that will help you.

In the Developer Options, several settings allow you to get some more autonomy. And two of these options are practical: “Mobile data always active” and “Wi-Fi scan throttling”. Both are intended to reduce the time away from an active Internet connection, but they can be switched off without reducing the usage experience too much. We find this highly recommended.

Here’s how to disable both network features from Developer Options:

First step

To begin with, it is essential to enable the “Developer options”. To do this, go to the settings of your Android. Then find the “About phone” section. Next, locate the “Build number” and press that option 7 times until you see a message saying “You are now a developer”. This activates the “Developer options”. There is a possibility that you will have to authorize unlocking your phone.

Second step

Then go back to the main “Settings” menu and go to the “System” section to locate the new “Developer options”. For each brand of phone, this may vary: they are usually located under “System”.

Third step

After that, swipe down in the Developer Options menu until you find the “Wi-Fi scan throttling” setting and enable it.

Fourth step

Finally, just look for the “Mobile data always active” option and turn it off. And that’s it!

Conclusion

By configuring these two functions of WiFi and mobile connectivity in the background your Android device will stop searching for networks constantly and, when connected to a known WiFi, it will disable mobile data so as not to waste resources when they are unnecessary (you can also completely disconnect the WiFi and activate it only when you are under your known networks). In return, it may take a few seconds longer than usual for your phone to connect to the Internet when you leave the WiFi coverage, nothing that would be problematic. Remember to try these options and let us know your experience in the comments. Thanks for reading us. Goodbye!

SysInspector

ESET has created a program called SysInspector. It is a very easy-to-use diagnostic tool that will help you solve numerous system problems. It can be obtained both integrated in the antivirus suite, and independently.

CPU-Z / CPU-X

This other program provides a lot of details about the CPU. Not only information about it, but also about the memory, tests, and something important, the voltages and frequencies at which it is working. Something that can be essential to detect problems, especially if you have done overclocking.

As CPU-Z is only available for Windows, CPU-X is the alternative for GNU/Linux which is exactly the same.

Intel Processor Diagnostic Tool

Intel Diagnostic Tool is compatible with Windows, and allows you to verify the functionality of the Intel processor. In this sense, it provides information such as frequency, voltages, and other characteristics. It also performs stress tests on the processor to see if the instability or failures you are suffering are due to it or to another component.

WiFi Analyzer

It is a complete suite that can perform a great amount of wireless network analysis. For example, some of the options you have at your disposal are:

• Checking the channels of nearby Wi-Fi networks to detect which channels enjoy higher quality.
• Checking the Wi-Fi signal strength to rule out or certify that the problem is that.
• Obtain information from each detected Wi-Fi network separately.
• Save information from the reports obtained to view at any time.

Angry IP Scanner

This utility is available for multiplatform. It is compatible with Windows, macOS, and Linux. This free app is used to track and export the results of a network scan in order to detect network problems. For example, IP hops, latencies or ping, used servers, ports, etc.

CrystalDiskInfo

Thanks to the S.M.A.R.T. technology of HDD and SSD hard drives, it is possible to detect health problems of a hard drive before it fails irreversibly. This could help detect issues and prevent data loss. Well, what this program for Windows does is to obtain information thanks to this technology. As a result, it provides information about the health status. For example, you can check the operating temperature, firmware, and disk information. In addition to an analysis with the state of health that will indicate if it is going to fail soon or not.

CCleaner

CCleaner is a well-known Windows program. In principle, it can be used for maintenance tasks such as cleaning some temporary or cache data. It also serves to repair the Windows registry, another of the sources of problems that can occur in the system. However, it also has other functions. For example, freeing up space or searching for duplicate files that are making your hard drives cluttered and slow.

How to configure Windows not to scan for Wi-Fi

By default, Windows is configured to constantly scan for Wi-Fi connections. This is certainly handy. However, you may wish to do without it, in order to extend battery life. Or to save resources. Well, let’s see how to do it. It is a very simple procedure and for which we will not have to install any additional plugins. We are only going to use the operating system’s own configuration.

The first thing we are going to do is to go to Start, look for services and access. There we will see a large list of operating system services that we will be able to modify. All of them will be configured as they come when installing the OS, unless we have made some change. We can also access simply with the key combination Windows+R and execute services.msc.

When you are at this point, look for the WLAN Auto Config service. We have to click with the right button of the mouse and click on Stop. Then go to Properties and under Startup type, which will be marked as Automatic, change it to Manual.

Once this is done, we simply have to click on Apply and we will accept the changes. From this moment on, Windows will not be searching for Wi-Fi networks automatically. We must also restart the computer for the changes to take effect correctly.

You should know that this change is totally reversible. Consequently, it is possible to return to the previous scenario. That is, Windows will automatically search for networks again. Consequently, we only have to follow the steps that we have explained again. Only this time, we switch back to Automatic. Press OK, restart the computer, and that’s it.

How to prevent Windows from connecting to a specific network

After having explained what we can do to prevent Windows from automatically searching for Wi-Fi networks, we are now going to focus on preventing it from connecting to a specific network. It is possible that we do not want it to automatically access a Wi-Fi to which we have previously connected. Even to an access point we have at home. This can also be done easily. It can be interesting for the same reasons as mentioned above. It is especially useful for not connecting only to a certain network that has a weak signal.

Windows configuration

If at some point we connect to a network, and now we do not want it to connect automatically, we can avoid it. To do this, we have to follow these steps. First, go to Start and then go to Windows Settings. Then we go to Network and Internet, click on Wi-Fi and access Manage known networks.

A list of all the wireless networks to which we have ever connected will be displayed. It does not matter if they are open networks or have passwords. What Windows does is to store this information to connect quickly as soon as it detects it. It is interesting to save time, but sometimes we may not want this.

What we need to do is to find the network we do not want to connect to. It can be a Wi-Fi repeater, for example. We click on the name, and we will see a small box where we will see the Forget button.

By simply performing this step, Windows will automatically stop connecting to that wireless network. It will delete all stored information. In addition, this also includes the password. If in the future, we want to connect again, we will have to click on Connect and manually enter the password.

Therefore, following these steps, we can also prevent Windows from automatically connecting to a specific network. It is an alternative if we do not want that it stops looking for networks constantly, but we are not interested that it can connect to a certain network. It is a simple and fast process. In addition, we can easily revert reverse it easily if in a given moment we are interested that it returns to connect.

How to do it from the command prompt.

We can also do this using commands. Moreover, in this case, it would be valid both for networks we are connected to now and for those we are not connected to. In short, it is valid for any network that we have saved. An important issue is that to execute these commands, it is mandatory to do it as an administrator. To do so, type and select Run as administrator. Also, by clicking on Command Prompt with the right mouse button, this option appears.

Now we are going to use a command to view the profiles of the saved Wi-Fi networks. With this in mind, we will use netsh with the following parameters:

netsh wlan show profiles

In case we want to prevent Windows from automatically connecting to a Wi-Fi network, we will have to use this other command:

netsh wlan set profileparameter name=network name connectionmode=manual

Here, what we have to do is to replace Network Name with the name of the Wi-Fi network you want to modify. This would be the command in which our Wi-Fi network profile has been executed correctly, so that from now on the connection is made manually.

Instead, this would be the command syntax if we want that Wi-Fi network to start automatically:

netsh wlan set profileparameter name=network name connectionmode=auto

This is the example of the execution to have an automatic connection:

In the hypothetical case that we do not know if we have the Wi-Fi connection on automatic or manual, we would use this other command:

netsh wlan show profile network name

These are the results we would get if that Wi-Fi network has automatic connection:

Very well, this way we begin to see how to manage the Wi-Fi connections with Windows 11. Bye!

Choose which applications to transfer

The first step before passing one or another application is to sort each of them, it is also important that you know if you use it often. We will always have some above others, try to prioritize and put each of the swipes at a point where you can get to it quickly, for example on the first screen.
Also remember that if you pass an app to another phone it will not always carry all the information, starting from zero, so it is convenient to configure and pass the information. Always try to pass a test that works correctly and does not contain any errors, which would make you have to uninstall and reinstall from the store.
There is an official Google way to move applications from one mobile to another. Certain apps from Google Play are useful to transfer one or more utilities quickly and without having to go one by one to the new terminal.

Use the official Google method

It is probably the most used by anyone. When you want to move an application from one phone to another use this method known as conventional. The important thing is to have autonomy in both. If this does not happen any of them should go through the charging station. If you want everything to be a success. The previous steps are a few, try not to skip any. If what you want is to get the app to work on your new device once it has been passed. Android smartphones usually communicate well and if you pass a utility it is usually done fully, the files are complete, and it will pass a complete folder.

First use the previous steps, which are:

• The first point is to have both devices fully charged.
• The main phone must be unlocked.
• Once again on the previous device, log in to your Google account. Then create a backup with Drive and verify that you are connected to a WiFi connection.

To move the entire app from one phone to the other, do the following:

• Turn on the new phone and press “Start”
• Then connect to the WiFi network and choose to copy the applications and data from the previous phone.
• One option is to be able to pass the data with cables, it is an option other than Bluetooth/WiFi.
• Now click on “Backup” on the new one and click on “Confirm”, just choose the apps and nothing else.
• Follow the steps and confirm to have all the apps on that new smartphone you have in your possession.

This way you will be able to transfer the apps to your new device without any inconvenience. Thank you for reading us Bye!

Create a portable access point

This is one of the most commonly used options when it comes to sharing your Internet connection, and it is also the most versatile because it allows any other device with Wi-Fi connectivity to connect, from a TV to a tablet or an eBook.

• Open Settings
• Click on Portable Hotspot
• Enable Portable Hotspot
• Tap on Configure to modify data such as the password

Your phone will work as a router, so it will be valid with any other Wi-Fi device, and also in current phones gives the option to create a 5 GHz or 2.4 GHz network, as well as being able to change the password or even delete it.

Of course, you should keep in mind that this particular method consumes a little more battery than the rest, so the best option will be to have your phone charged, or at least the charger is not far away. It is the most versatile, but that does not mean that it is the one you have to always use, as there are many occasions when other methods may be more convenient.

By a USB cable

If you want to share your Internet connection with a computer, this is the easiest and most recommended method, since you will only have to connect the charging cable from your phone to the computer and activate the option to start working, without the need to put the password as in the access point. Just follow these steps:

• Open Settings
• Click on Portable Hotspot
• Connect your phone to the computer via USB
• Enable USB tethering

If you are working away from home with your laptop or you have simply run out of Internet, it is a very simple and safe option, and your phone will be charged while sharing the Internet thanks to the energy that will come from your computer, so in terms of energy, it is all advantages.

Via Bluetooth

Current Android smartphones also offer the option to share your Internet connection via Bluetooth, which is uncommon today, but it is an interesting possibility, and in which you will not have to do anything more than activating the option. Follow these steps:

• Open Settings
• Go to Portable Hotspot
• Enable Bluetooth tethering

And will be the person who wants to connect who will have to open the Bluetooth on your device and connect to the phone from which you are sharing the connection. This is a useful method for devices that do not have WiFi, but Bluetooth. Thanks for reading. Bye bye!

Windows stores passwords in our account

There is really no need to save Wi-Fi passwords when you plan to format your hard disk or change your computer. With the release of Windows 8, Microsoft began to implement the integration of the operating system with the user account. In this way, Microsoft wanted to make it easier to interact with devices in the future. The main advantage of this change is with respect to the Microsoft Store. Thanks to this integration, we could access a list of applications that we had previously downloaded. In fact, these had already been associated with our account.

Subsequently, Microsoft also started to associate the hardware of the device with the license. In this way, we could only use the corresponding license on a single device. That is, we could not use it on different computers together. As Windows evolves, Microsoft has been introducing a series of hidden improvements. One of them is being able to store in the Microsoft cloud a copy of all the Wi-Fi networks we have connected to in the past. It is enough to associate a Windows installation to our account. No matter if it is a new computer or a formatted one. As a result, the list with all the access points and the passwords for each of them will be automatically downloaded. Therefore, it will not be necessary to enter the access data again.

Is there anything else we should do?

Remember that this process is done automatically when you enter the data. So there is really no need for any further action on our part. In the same way, the new access points to which we connect are automatically synchronized. Therefore, if we delete any of them, they will also be automatically deleted from the Microsoft servers. This also happens on all computers that are managed by the same Microsoft account, even if they are different computers.

How to know the password of a Wi-Fi network

Windows provides a couple of methods to learn stored Wi-Fi passwords.

From settings

From Windows Settings, we will only be able to know the password of the currently connected network. In fact, there is no option to know the password of all the access points we have stored on our computer. To obtain the password of the Wi-Fi network in which we are, we access the Windows configuration options by pressing Win+I.

Once there, we entered Network & Internet. Within this section, click on Wi-Fi. Then, in the right column, click on Network and Sharing Center.

Next, the Windows Control Panel will be displayed. Specifically, in the section corresponding to the networks. In this section, click on the name of the connection to access its properties.

Then, a new window will be displayed. There we will see the operation, connection type, speed, and duration of the Wi-Fi connection in which we are. In this window, click on Wireless Properties.

Next, we click on the Security tab and check the box Show characters. At that moment, Windows will ask us for the security method that we use in our account to be able to show it. If we do not know it, Windows will not show us the password of the network to which the equipment is connected.

A network, with or without internet access, is the only method of sharing files and resources between devices. Any person who has access to the network has access to all that content. For this simple reason, Windows will ask for the PIN of the user account in which we are. Otherwise, we will be able to use the command prompt or the PowerShell, as we will see next.

Using Command Prompt

If you do not have access credentials to the computer, then you can resort to the command prompt. In addition, this option allows us to know the password of all the access points registered on the computer. Remember that this possibility is not available from the Windows graphical interface. The first thing you have to do is to go to the command prompt. With this in mind, enter the term CMD in the Windows search button. Please remember to open it with administrator privileges. Next, we use the following command to list all the Wi-Fi networks to which we have connected with the computer and with that user account.

netsh wlan show profile

Next, we must select the name of the Wi-Fi connection for which we want to know the password. Then please use the following command. Please replace wifiname with the name of the access point. The Wi-Fi network code will be displayed under Key content.

Netsh wlan show profile name="wifiname" key=clear

We must carry out this process individually. In other words, we cannot create a list of all the passwords of the access points to which we have connected. In fact, we will have to do it one by one. Very well, in this way we have seen how to back up Wi-Fi passwords on Windows. Bye!
