ImageMagick error on Windows: “magick: unable to open image ”test’: No such file or directory @ error/blob.c/OpenBlob/3565. magick: no decode delegate for this image format `’ @ error/constitute.c/ReadImage/741.” (SOLVED)

If in Windows 11 open CMD:

cmd

And then run the command:

magick '.\Для теста.jpg' test.png

An error will be received that there is no such file or directory:

magick: unable to open image ''.\╨Ф╨╗╤П': No such file or directory @ error/blob.c/OpenBlob/3565.
magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/741.

You can see that non-Latin characters are used in the file name, so you might think that this is the problem – that is, the “magick” program does not support alphabets other than English.

But if you try to rename the file and run the following command:

magick 'test file.jpg' new.png

Then the same error will be received again:

magick: unable to open image ''test': No such file or directory @ error/blob.c/OpenBlob/3565.
magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/741.

How to fix “magick: unable to open image ''test': No such file or directory @ error/blob.c/OpenBlob/3565. magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/741.”

1. Use double quotes instead of single quotes

If the filename is enclosed in double quotes instead of single quotes, then the command works correctly:

magick ".\Для теста.jpg" test.png

That is, try putting the filename in double quotes. If the problem persists, then it is related to the encoding of the file name.

2. Use PowerShell instead of CMD

In Windows 11 and Windows 10, the default command prompt is PowerShell, not CMD.

If your Windows uses CMD by default, then either set it to use PowerShell in the settings, or run one of the following commands at the command prompt:

powershell
pwsh

In Windows 11 + Windows Terminal Preview + PowerShell 7 command

magick '.\Для теста.jpg' test.png

works without errors.

Some program areas become transparent or invisible in guest OS Windows after upgrading to VirtualBox 7 (SOLVED)

The big update to VirtualBox 7 brought a lot of changes and, apparently, bugs. Some of them have already been covered in the post “Windows stopped booting in Virtual Machine after upgrading to VirtualBox 7 (SOLVED)”.

While working with a guest OS Windows 11 in VirtualBox 7, new issues were discovered, some of which were resolved, and some are still not resolved. In this note, we will look at how to fix the problem with invisible areas of programs.

This error does not occur in all programs, so I did not immediately pay attention to it. For example, the MS Word office editor window looks like this in the guest OS:

This is what the opened document looks like:

You may notice that the background of the context menu is transparent, although it shouldn't be.

Another unexpected transparency.

Search results are not visible in the “Settings” app due to inappropriate transparency.

It's an open Notepad with text in it.

The menu for closing a document looks like this.

How to fix transparency in Windows guest in VirtualBox 7

The problem was solved in the following way:

1. Shut down the guest OS

2. Go to its settings → Display.

Uncheck “Enable 3D Acceleration”.

3. Boot guest OS with Windows as usual

Now MS Word and the context menu look normal:

Notepad is working now.

Warning about unsaved changes looks correct now.

In the “Settings” app, search results are now on an opaque background so they're easier to read.

Windows stopped booting in Virtual Machine after upgrading to VirtualBox 7 (SOLVED)

After upgrading to VirtualBox 7 (more precisely, to VirtualBox 7.0.2), the Windows 11 guest OS stopped booting.

Windows 11 guest boot starts as usual, no errors are displayed. Moreover, you can hear the Windows logon sound, but the desktop is not shown.

Boot freezes on the initial screen with UEFI messages.

As a host (main) OS, I use Linux, namely Arch Linux.

The problem was solved in the following way:

1. Shut down the guest OS

2. Go to its settings → Display.

Uncheck “Enable 3D Acceleration”.

3. Boot guest OS with Windows as usual

4. Update Guest Additions.

5. After that, you can again activate the “Enable 3D Acceleration” setting – the guest system will boot without errors.

Hangups while updating Guest Additions

One of the innovations of VirtualBox 7 is the automatic updating of the Guest Addition.

But in my case, after inserting Guest Additions CD image, an error occurred and the virtual computer hung.

In addition to the problem discussed just above, I noticed that the Windows guest OS, after inserting the “Guest Additions CD image”, tried to update them on its own. This led to endless freezes and the need to force a reboot of the guest OS.

Finally, the problem was solved in the following way:

1. Remove Guest Additions (if your guest OS keeps freezing then boot into safe mode)

2. Restart your computer

3. Reinstall the Guest Additions

4. Restart the computer again

Should I upgrade to VirtualBox 7?

At the time of writing, the latest stable version is VirtualBox 7.0.2, which was released just a few days after the release of the first stable version of VirtualBox 7.

However, according to my observations, Windows 11 is still unstable in VirtualBox 7.0.2.

Although VirtualBox 7 brings significant updates, they are not in demand by most users who run virtual machines in VirtualBox. If you do not see anything important in the changelog in VirtualBox 7, then I would recommend waiting a few months before upgrading. During this time, more problems and bugs will be fixed.

How to enable DNS over HTTPS in Windows 11

To improve your online privacy and security, Windows 11 lets you use DNS over HTTPS (DoH) to encrypt the DNS requests your computer makes when you browse or do anything else on the Internet. This article will show you how to set it up in Windows 11.

Encrypted DNS is more private and secure

Every time you visit a website using a domain name (such as “suay.site”), your computer sends a request to a Domain Name System (DNS) server. The DNS server takes the domain name and looks up the corresponding IP address from the list. It sends an IP address back to your computer, which is then used to connect to the site.

See also: How to enable DNS over HTTPS and what it is for

This process of getting the resolution of a domain name to an IP address traditionally took place on the network in the plain text. Any intermediate point can intercept the transmitted information – the domain names of the sites you visit and their IPs. With DNS over HTTPS, also known as DoH, communication between your computer and a DoH-enabled DNS server is encrypted. No one can intercept your DNS requests to track the addresses you visit or spoof responses from a DNS server.

First, choose a free DNS with DoH support – there are already a lot of them now

Starting with the release of Windows 11, DNS over HTTPS in Windows 11 only works with a certain hard-coded list of free DNS services (you can see the list yourself by running

netsh dns show encryption

in the terminal window).

Here is the current list of supported IPv4 DNS server addresses as of October 2022:

  • Primary Google DNS: 8.8.8.8
  • Additional Google DNS: 8.8.4.4
  • Cloudflare Primary DNS: 1.1.1.1
  • Secondary DNS Cloudflare: 1.0.0.1
  • Primary DNS Quad9: 9.9.9.9
  • Secondary DNS Quad9: 149.112.112.112

For IPv6, list of supported DNS server addresses:

  • Primary Google DNS: 2001:4860:4860::8888
  • Google Secondary DNS: 2001:4860:4860::8844
  • Cloudflare primary DNS server: 2606:4700:4700::1111
  • Additional Cloudflare DNS: 2606:4700:4700::1001
  • Primary DNS Quad9: 2620:fe::fe
  • Secondary DNS Quad9: 2620:fe::fe:9

When it comes time to enable DoH in the section below, you will need to select two pairs of these DNS servers – primary and secondary for IPv4 and IPv6 – to use with your Windows 11 PC. As a bonus, using them will likely speed up your Internet experience.

Enable DNS over HTTPS in Windows 11

To start configuring DNS over HTTPS, open the Settings app by pressing Win+i on your keyboard. Alternatively, you can right-click the Start button and select “Settings” from the special menu that appears.

In Settings, click “Network & internet” in the sidebar.

For “Wi-Fi” and “Ethernet”, the procedure for setting up DNS over HTTPS is slightly different.

Configuring DNS over HTTPS for Ethernet (Wired)

In Network & internet, click the name of your primary Internet connection in the list, such as “Ethernet”.

On the Ethernet properties page, find the “DNS server assignment” setting and click the “Edit” button next to it.

In the window that appears, select “Manual” DNS settings from the drop-down menu.

Then turn the “IPv4” switch to the “On” position.

In the IPv4 section, enter the primary DNS server address you selected in the section above in the “Preferred DNS” field (for example, “8.8.8.8”).

The drop-down list “Preferred DNS encryption” will become active. In this list, select “Encrypted only (DNS over HTTPS)”.

Similarly, enter the address of the secondary DNS server in the “Alternate DNS” field (for example, “8.8.4.4”). The drop-down list “Preferred DNS encryption” will become active. In this list, select “Encrypted only (DNS over HTTPS)”.

If your ISP supports IPv6, then repeat this process with IPv6. If your ISP does NOT support IPv6, then you DO NOT need to enable IPv6 DNS servers. If you're unsure, it's best not to enable IPv6 DNS.

Switch the IPv6 switch to the On position, and then copy the primary IPv6 address from the section above and paste it into the “Preferred DNS” field. Then copy the appropriate secondary IPv6 address and paste it into the “Alternate DNS” field.

After that, set both “Preferred DNS encryption” options to “Encrypted only (DNS over HTTPS)”.

Finally, click “Save”.

Back on the Ethernet hardware properties page, you'll see a list of your DNS servers with “(Encrypted)” marked next to each one.

Configuring DNS over HTTPS for Wi-Fi (Wireless)

In Network & internet settings, click the name of your primary Internet connection in the list, such as Wi-Fi.

On the Wi-Fi properties page, go to the “Hardware properties” section.

On the next window, locate the “DNS server assignment” option and click the “Change” button next to it.

In the window that appears, select “Manual” DNS settings from the drop-down menu. Then turn the “IPv4” switch to the “On” position.

In the IPv4 section, enter the primary DNS server address you selected in the section above in the “Preferred DNS” field (for example, “8.8.8.8”).

The drop-down list “Preferred DNS encryption” will become active. In this list, select “Encrypted only (DNS over HTTPS)”.

Tip: If you don't see the “Preferred DNS encryption” settings, then you are editing the DNS settings for a specific Wi-Fi connection and not for the wireless adapter as a whole. Make sure you have selected the connection type in Settings → Network & internet, then click “Hardware properties” first.

Similarly, enter the address of the secondary DNS server in the “Alternate DNS” field (for example, “8.8.4.4”).

If your ISP supports IPv6, then repeat this process with IPv6. If your ISP does NOT support IPv6, then you DO NOT need to enable IPv6 DNS servers. If you're unsure, it's best not to enable IPv6 DNS.

Switch the IPv6 switch to the On position, and then copy the primary IPv6 address from the section above and paste it into the “Preferred DNS” field. Then copy the appropriate secondary IPv6 address and paste it into the “Alternate DNS” field.

After that, set both “Preferred DNS encryption” options to “Encrypted only (DNS over HTTPS)”.

Finally, click “Save”.

Back on the Wi-Fi hardware properties page, you'll see a list of your DNS servers with “(Encrypted)” marked next to each one.

That's all you need to do. Close the Settings app, and you are ready to go. From now on, all your DNS requests will be private and secure. Happy viewing!

Note. If you're having network problems after changing these settings, make sure you've entered the correct IP addresses. An incorrect IP address can cause DNS servers to be unavailable. If the addresses are entered correctly, try disabling the “IPv6” switch in the list of DNS servers. If you are configuring IPv6 DNS servers on a computer that is not connected to IPv6, this can cause connectivity issues.

Apache window appears and immediately disappears (SOLVED)

When I click on httpd.exe, a black window flickers and then disappears

Apache (httpd) is a command line utility. Strictly speaking, this is a service that is designed to run in the background without a graphical interface. That is, Apache does not have a graphical interface in the form of a familiar window. Therefore, Windows users may feel that the program starts in an unusual way.

To run the program, you need to open a Windows Terminal window (or PowerShell). To do this, press the key combination Win+x, and select Windows Terminal (Admin):

Then you can proceed in two ways.

The first option: you can simply drag and drop the executable file into the command line window. The executable is httpd.exe.

The second option: on the command line, you can change the current working directory to the one where the Apache executable files are located. For example, my program is located in the C:\Apache24\bin\ folder, to change the current working folder, the cd command is used, after which the folder to which you want to go is indicated, in my case the command looks like this:

cd C:\Apache24\bin\

As you can see from the screenshot, the C:\Users\MiAl folder has been changed to C:\Apache24\bin\.

Now, to run the program, it is enough to type the name of the executable file indicating the current folder. The current folder is indicated by a dot (.), then you need to put a backslash, it turns out like this:

.\httpd.exe

Apache is a network service, that is, a program that uses a computer network for its work. Specifically, Apache listens for incoming connections on port 80 (opens a port). For this reason, the Windows Firewall asks whether to allow access to the Apache HTTP Server program, select “Allow access”.

Already at this stage, the web server is running and you can open the address http://localhost/ in a web browser

To stop the service, press Ctrl+c.

Typically, command-line utilities support various options that can be specified with a space after the executable file name.

Also, utilities usually have built-in help on available options, which can be displayed using the -h option or the --help option.

For example:

.\httpd.exe -h

In addition to command line options, many services are configured using configuration files, which are text files with a specific syntax. For Apache in Windows this is the C:\Apache24\conf\httpd.conf file.

To get a complete web server with all the necessary components, follow the steps from the guide “How to install Apache web server with PHP, MySQL and phpMyAdmin on Windows”.

How to connect a TV to a computer in Windows 11

Is it possible to connect a TV or a second monitor to a computer in Linux

This guide will show you how to connect a TV or a second monitor to a computer in Windows 11. It will also talk about the available settings and solutions to common problems that arise when connecting a TV to a computer.

If you are a Linux user, then see the articles:

What you need to connect a TV or an additional monitor to a computer

To connect a TV or a second monitor to a computer or laptop, you need:

  • TV with HDMI connector (all modern models) or monitor with HDMI connector (all monitors released in the last two decades)
  • a computer with an HDMI connector – almost all computers and laptops will fit
  • HDMI cable

Choosing an HDMI cable

I approached the choice of HDMI cable quite simply – I chose the cheapest with the right length, which I found in the store. In subsequent use, this cable fully satisfied my needs.

Despite its cheapness, this HDMI cable supports:

  • UHD 4K@2160P / 4K@60Hz / 4K HDR
  • High Speed HDMI 2.0
  • Gold plated contacts

Cable length 1.8 meters.

Apparently, these are already the minimum characteristics – perhaps more expensive models support higher resolutions and data transfer at higher speeds.

What TV can be connected to a computer

Using an HDMI cable, you can connect any TV with an HDMI connector. This connector is present on all TVs and monitors released in the last decade.

Older TVs without an HDMI connector can also be connected to a computer, but instead of an HDMI cable, you will need a wire with an adapter.

As for the technical characteristics of the TV (diagonal size, screen resolution, screen refresh rate, aspect ratio), this is not critical. That is, you do not have to select a TV model with the same characteristics as your monitor. Modern video cards support a variety of modes (screen resolutions and refresh rates), including the video card will work with a TV if the screen resolution is different from the monitor.

For example, the characteristics of my devices:

  • laptop monitor: 17", 1920×1080, 16:9, 120 Hz
  • TV (all specifications): 32", 1366x768p, 16:10, 60Hz

That is, these are two very different devices, but at the same time I had no problems when they worked together.

How to connect HDMI cable to TV

Plug the HDMI cable into the connectors of the computer (laptop) and TV.

Both on the computer and on the TV, there may be several HDMI connectors – remember the number of the selected connector.

Turn on your computer and TV.

Note: The HDMI cable can be connected when the computer and TV are already on.

Use the remote control to select “HDMI” as the input source on the TV.

If, after selecting HDMI as the signal source on the TV, you see the message “No Input Signal”, then:

  1. Select HDMI with a different number.
  2. Move the wire, it may not be firmly connected to the computer or TV socket.
  3. Make sure your computer is on.
  4. The monitor on the computer should not be turned off due to inactivity.

How to use a TV connected to a computer

There are two main modes:

  • join displays
  • mirror (duplication) of images on both displays

When displays are combined, the total space expands. That is, if you connected another 1920×1080 display to a computer with one 1920×1080 display, then now the resolution of your virtual screen becomes 3840×1080, if there are three such displays, the resolution will become 5760×1080. You can drag program windows from one display to another. Some apps and games support these wide virtual screens.

When the image is repeated (Mirror), the same image will be shown on both displays.

Among the displays, Primary stands out. This is the one connected first. A feature of the main display is that it shows desktop shortcuts, although this can be changed in the settings.

In the next video, the TV is connected to the computer. To play a YouTube video on a TV, the web browser window is dragged from the monitor to the TV.

Where are the settings for the second display and TV

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Here you will see the display settings.

Select the display (or TV) you want to customize.

At the top of the settings window, you'll see a display layout.

The “Multiple displays” settings area appears only if multiple monitors (TVs) are connected to the computer, it contains settings for the computer's behavior when working with multiple displays. To see these settings, click on the arrow icon on the right side.

The following are settings common to all displays.

Then at the bottom of the window are settings specific to each display.

Select a monitor to change its settings.

The following settings are individual for each monitor:

  • Scale
  • Display resolution
  • Display orientation

When you go to the “Advanced display” settings section, you will also be able to adjust the refresh rate for each of the displays.

How to set Main (Primary) Monitor

By default, desktop shortcuts are shown on the Main Display. You can change, i.e. choose a new primary monitor. For this:

1. Open the “Settings” application, this can be done by pressing Win+i.

2. Go to the “Display” section.

3. Select the display you want to make Primary.

4. Expand the “Multiple displays” settings area.

5. Check the “Make this my main display” checkbox.

How to turn off the display or TV in the settings, without physically disconnecting

You can disconnect the HDMI cable from your TV or computer at any time, but this is not always convenient. In addition, you may want to turn off the computer monitor or the laptop's built-in monitor.

To turn off any monitor or TV in Settings, open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Below the monitor layout, you will see a drop-down list of the following items:

  • Duplicate these displays
  • Extend these displays
  • Show only on 1
  • Show only on 2

Selecting the “Show only on…” option will cause the image to be displayed on only one display (or TV), and all others will be disabled.

A disabled monitor will stop working (it will no longer receive an input signal), but the disabled monitor will still be available in the settings. You can turn it back on at any time. To enable all monitors, select one of the following options from the drop-down list above:

  • Duplicate these displays
  • Extend these displays

How to make the TV show the same thing as the monitor

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Under the monitor layout, select “Duplicate these displays” from the drop-down list.

As a result, the resulting settings for both monitors at once will be shown.

Now the image on the monitor and TV is the same:

You may notice that the picture on the TV is slightly cropped.

This may be due to the aspect ratio or screen resolution.

In my case, both the aspect ratio and the screen resolution of the monitor built into the laptop and the TV are different. Changing the screen resolution to what the TV has somewhat reduced the problem with cut edges.

How to make the TV become an extension of the monitor

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Under the monitor layout, select “Extend these displays” from the drop-down list.

In this case, one of the monitors will be considered the main one. In this case, each of the monitors will show its own desktop, which, in fact, is one.

Why can't I drag the program window to the second screen

If you see two displays in the settings, but you can’t drag the program window to the TV or the second display, then try dragging the window to the other side. That is, if you, for example, are trying to drag a program window to the left side, then try dragging it to the right side instead.

The fact is that the physical location of the second monitor (TV) and its location in the settings can be different. To fix this, swap the monitors in the settings.

In addition to the location of the monitors to the left and right of each other, other options are possible.

You can place one of the monitors (or TVs) above the other.

In this case, the screen resolution and desktop area will change accordingly.

If you have many monitors, you can place them however you want, not all monitors need to be in a straight line horizontally. You can arrange them, for example, as 3×2, that is, two rows of three monitors.

How to make the Taskbar only show on the Main monitor

If you want the taskbar to be shown only on the Main monitor, then follow the steps below.

Open the “Settings” app by pressing Win+i.

Go to “Personalization” → “Taskbar”.

Expand the “Taskbar behavior” section.

Uncheck the “Show my taskbar on all displays” setting.

How to make the taskbar show on all monitors

If you want the taskbar to be shown on all connected monitors and TVs, then follow these steps.

Open the “Settings” app by pressing Win+i.

Go to “Personalization” → “Taskbar”.

Expand the “Taskbar behavior” section.

Check the box next to “Show my taskbar on all displays”.

After that, the Taskbar will be shown on all monitors.

How to set different desktop wallpapers for monitor and TV

You can set a different desktop wallpaper for all connected monitors and TVs.

To do this, open the “Settings” application, this can be done by pressing Win+i.

Go to “Personalization” → “Background”.

Right click on the photo you want to set as your desktop wallpaper. From the pop-up menu, select the number of the monitor for which you want to set this desktop background.

Now the desktop wallpaper on the monitor and TV is different.

How to identify displays

If you have multiple monitors and you are confused about their settings, then you can enable the display of the number on the screen of each monitor.

Open the “Settings” app by pressing Win+i.

Go to the “Display” section.

Click the “Identify” button, which is located under the schematic image of the monitors.

After that, each monitor and TV will show squares with display numbers in the settings.

Why is the sound played through a computer (laptop) and not through a TV

An HDMI cable can carry both video and audio. But even after connecting the TV with an HDMI cable, sound is still output from the laptop speakers or computer speakers.

To change the audio output source, go to the audio settings. To do this, open the “Settings” application, this can be done by pressing Win+i.

Go to the “Sound” section.

In the “Output” section, select “Audio for Displays”.

You can also expand the settings for each sound source by clicking the arrow symbol to the right of the source name. In the window that opens, you can fine-tune each sound source.

Why did the sound disappear after turning off the TV on the laptop (computer)

To change the audio output source, go to the audio settings. To do this, open the “Settings” application, this can be done by pressing Win+i.

Go to the “Sound” section.

In the “Output” section, select “Speakers”.

Setting the action when closing the laptop lid when using a second monitor

If you are using a laptop, closing the laptop lid when additional monitors are connected to it may not be what you expect. For example, when you close the laptop lid, the computer goes into Sleep mode or shuts down, but you expect to be able to work on a second monitor or watch TV connected to the computer.

To control how the computer behaves when the laptop lid is closed, open the “Control Panel”.

In the Control Panel, go to “Category” → “Small icons”.

Open the “Power Options” section.

Click on the “Choose what closing the lid does” link.

You can also go to this setting by running the command:

control /name Microsoft.PowerOptions /page pageGlobalSettings

In the window that opens, note that all actions are configured for two modes:

  • On battery
  • Plugged in

For the action for “When I close the lid”, select “Do nothing”.

How to prevent the monitor from turning off

If there is no activity for some time (for example, 10 minutes), the monitors will be turned off. You can disable the setting to turn off displays.

To control when monitors turn off due to inactivity, open the “Control Panel”.

In the “Control Panel”, go to “Category” → “Small icons”.

Open the “Power Options” section.

Click on the “Choose when to turn off the display” (or “Change when the computer sleeps” link).

You can also go to this setting by running the command:

control /name Microsoft.PowerOptions /page pagePlanSettings

In the window that opens, note that all actions are configured for two modes:

  • On battery
  • Plugged in

Set longer time intervals before turning off the monitor and entering sleep mode, or select “Never”.

6. “The connection with the Bluetooth network device failed” error

7. Why is the Internet speed slow over Bluetooth


In this tutorial, you will learn how to set up an Internet connection via Bluetooth in Windows, as well as why the Internet speed via Bluetooth is slow.

1. How to connect my computer to the Internet through my phone via Bluetooth

Internet via Bluetooth is one of the options for using a mobile phone to access the Internet from a computer. Looking ahead, we note that this is not the best option because:

1) the connection speed will be quite slow,

2) the setup, although generally simple, is slightly more complicated than other connection options

As alternative methods for accessing the Internet from a computer via a mobile phone, the following are recommended:

If your computer does not have Wi-Fi and you do not have a USB data cable for connecting your phone by wire, then the method described in this article is suitable for you – accessing the Internet via the mobile phone's Bluetooth tethering.

The connection algorithm is as follows:

  1. Pairing your phone and computer via Bluetooth
  2. Turning on the Bluetooth tethering on the phone
  3. Setting up a computer, which consists in connecting to the phone's Bluetooth tethering (selecting Bluetooth as the Access point)

So, let's look at how to connect a computer to the Internet through Bluetooth and your mobile phone in Windows.

2. Connecting a mobile phone to a computer via Bluetooth (phone pairing)

Turn on Bluetooth in Windows if you haven't already. This can be done by clicking on the network connection button next to the clock.

In Windows, right-click on the Bluetooth icon and select “Go to Settings” from the context menu that opens.

Click the “Add device” button.

In the window that opens, select “Bluetooth”.

Turn on Bluetooth on your mobile phone.

Start Scan for Bluetooth devices.

If the devices do not see each other, then start searching for devices at the same time on the computer and mobile phone. If you don't succeed the first time, try again.

When the desired device is found, click on it to start pairing.

Do the same on the computer.

A prompt will appear on your mobile phone to establish pairing – agree to this proposal.

Do the same on the computer – click the “Yes” button.

Make sure the connection was successful.

If the connection fails, try again.

3. Turning on the Bluetooth tethering

Go to the settings of your phone, this can be done by unrolling the curtain from top to bottom and clicking the gear icon.

Further, the name of the settings items may differ on different phone models, but the essence will be the same everywhere.

Go to the “Connections” section.

Find the item “Mobile Hotspot and Tethering” there.

Turn on “Bluetooth tethering”.

   

4. Connect to a Bluetooth tethering on a computer

Right-click on the “Network” icon and select “Network and Internet settings” in the context menu that opens.

In the window that opens, select “Advanced network settings”.

Then select “More network adapter options”.

In the Network Connections window, find Bluetooth Network Connection, right-click it and select View Bluetooth Network Devices.

In the “Devices and Printers” window that opens, find the phone, right-click on it. In the context menu, select “Connect using” and select “Access point” in the list that opens.

After that, the computer will be connected to the Internet via the Bluetooth of the mobile phone.

5. How to Disconnect from a Bluetooth Connection

To turn off Bluetooth Internet on a computer

Right-click on the “Network” icon (next to the clock) → Advanced network settings → More network adapter options → Right-click on “Bluetooth Network Connection” → select “View Bluetooth Network Devices” from the context menu.

In the “Devices and Printers” window that opens, find the phone, right-click on it. Select “Disconnect from device network” from the context menu.

To turn off Bluetooth Internet on your mobile phone

Go to Settings → Connections → Bluetooth.

Click on the gear of the connection you are using.

Turn off “Internet connection sharing”.

6. “The connection with the Bluetooth network device failed” error

At the stage “4. Connect to a Bluetooth tethering on a computer” you may encounter an error:

The connection with the Bluetooth network device failed. The device may already be connected to another computer, or it may need to be configured to accept connections from this computer. Consult your device documentation for further information.

It usually means that you did not follow the steps described in step “3. Turning on the Bluetooth tethering”.

On the phone, you will be prompted to “Allow Bluetooth tethering”, if you select “Allow”, then the reconnection will be successful.

7. Why is the Internet speed slow over Bluetooth

When successfully connecting to the Internet via Bluetooth, the first thing you may notice is the speed of the connection. On the most modern Bluetooth 5.* protocols, it is up to 1.4 megabits per second (2 megabits per second at the moment). As you can see from the screenshot, the speedtest.net Internet connection speed test showed a speed of 1.66 megabits per second.

This is 210-220 kilobytes per second, if these units are more familiar to you. This is very slow, and on Bluetooth versions 4.* the speed is only 800 kilobits per second, that is, 2 times slower.

Thus, if the speed of the Internet via Bluetooth is too slow for you, all you can do to increase the speed of the Internet via Bluetooth is to switch to the Bluetooth 5.* protocol (both devices – the phone and the computer – must support this protocol). If this speed is not enough for you, then use Wi-Fi or data transfer via USB:

How to check Bluetooth version in Windows

To determine the Bluetooth version on a Windows computer, you need to open Device Manager.

This can be done in several ways at once:

1) Click on the start menu and start typing ‘Device Manager’, click on the suggested match.

2) OR open the ‘Power User Menu’ using the Win+x keyboard shortcuts and select ‘Device Manager’ there

3) OR press Win+r and type to execute:

devmgmt.msc

In Device Manager, find Bluetooth and expand the list:

Locate the Bluetooth adapter. Its name will vary depending on your specific hardware, but you should usually look for something like ‘Intel Wireless Bluetooth’ or ‘Bluetooth Adapter’.

The name itself may already indicate the version of the supported Bluetooth standard (as in the screenshot below). If so, you can ignore the next step since you have the answer!

If you're having trouble finding the right item in the list, one thing's for sure; the element you need to find in the list will not contain the word ‘Enumerator’, so ignore all such entries.

Double-click on the device name to open the properties of the device that you consider to be the primary Bluetooth adapter. You'll know right away if you're in the right element as you should see an ‘Advanced’ tab with content similar to the one shown below.

On this screen, you need to find the ‘Firmware Version’, i.e. HCI and LMP (Link Manager Protocol).

For example, on the screen you can see the version ‘10.256’. Now we need to convert the LMP version of the Bluetooth adapter to the actual supported Bluetooth version. Please note that your LMP version may be a decimal number. As you can see from the LMP table, any LMP number starting with 10 means that your adapter supports version 5.1 inclusive of the Bluetooth standard.

Link Manager Protocol Version (LMP)

Bluetooth Core Specification 

LMP 0

Bluetooth Core Specification 1.0b (withdrawn)

LMP 1

Bluetooth Core Specification 1.1 (withdrawn)

LMP 2

Bluetooth Core Specification 1.2 (withdrawn)

LMP 3

Bluetooth Core Specification 2.0 + EDR (withdrawn)

LMP 4

Bluetooth Core Specification 2.1 + EDR (deprecated, to be withdrawn)

LMP 5

Bluetooth Core Specification 3.0 + HS (deprecated, to be withdrawn)

LMP 6

Bluetooth Core Specification 4.0

LMP 7

Bluetooth Core Specification 4.1

LMP 8

Bluetooth Core Specification 4.2

LMP 9

Bluetooth Core Specification 5.0

LMP 10

Bluetooth Core Specification 5.1

LMP 11

Bluetooth Core Specification 5.2

The latest Bluetooth versions at the moment are 5.2 and 5.3. Still current specs 4.0/4.1 and later. If your adapter is older, using a new Bluetooth adapter on your computer may help improve the quality of your Bluetooth connection. If you are using devices that send a lot of data, such as constantly streaming audio or video, you really need to make sure that both the adapter and the device are compatible with at least Bluetooth version 3.0 + HS, and preferably 4.0 and later.

For reference: in version 5.*, the data transfer rate is doubled compared to 4.*.
