In today's digital world, connecting to a wireless network often requires quick authorization of gadgets, and using QR code has become the de facto standard for Android and iOS devices. However, users often face a paradoxical situation: they need to connect their phone, but the network password is only known on a desktop computer or laptop, which lacks built-in image generation functionality. This creates the need to find a way to view the Wi-Fi QR code on a computer so it can be read by the smartphone camera.
The problem is compounded by the fact that operating systems such as Windows 10 or Windows 11By default, routers don't have a built-in "Show QR code" button for saved networks in the graphical interface. Unlike Android, which generates the image automatically in the settings, a PC requires either third-party software or access to the router's web interface. Understanding these mechanisms allows you to quickly solve the problem without unnecessary fuss.
There are several proven methods for solving this problem, each depending on your specific hardware configuration and access rights. We'll cover methods using the router's web interface, specialized Windows utilities, and online generators. Choosing the right method will save you time and effort when setting up guest access.
Using the router's web interface to obtain the code
The most reliable and "native" way to see your network's QR code is to look in the router's settings. Many modern router models from manufacturers like TP-Link, Keenetic or ASUS have a built-in image generation function directly in the control panel. To do this, you need to know the gateway IP address and your admin login details.
Open any browser and enter the router address in the address bar, most often it is 192.168.0.1 or 192.168.1.1After authorization, look for the section related to the wireless network (Wireless or Wi-Fi). On some models, for example, in the interface Keenetic, the code is displayed directly on the main page or in the "My Networks and Wi-Fi" section.
If you don't find the image right away, check the "Guest Network" or "System Monitoring" sections. Some manufacturers hide this feature in the "Security Settings" or "WPS" subsection. It's important to understand that older router models may not visually support this feature, even if they are technically capable of transmitting data.
⚠️ Attention: Router firmware interfaces are frequently updated. The menu layout may differ from what's described, so look for the keywords "QR," "Scan," or "Mobile."
The advantage of this method is that you receive the latest code directly from the signal source. You don't need to install any additional software on your computer, which is especially important for corporate networks with restricted access to software installation.
Generating a QR code through online services
If accessing your router settings is impossible or too difficult, the quickest solution is to use specialized websites. There are many services that allow you to generate an image using only the network name (SSID) and a password. This is a universal method that works on any operating system.
To generate the code, you'll first need to know your current network settings. On a computer, you can do this by opening the connection properties. Go to Control Panel → Network and Internet → Network and Sharing Center, click on the name of your Wi-Fi network and select "Wireless Network Properties".
In the window that opens, go to the "Security" tab and check "Show entered characters" to see the password. Copy the network name and password, then go to any trusted QR code generator (such as QR Code Generator or similar). Select the "Wi-Fi" data type, enter the parameters, and click "Create."
Safety when using online generators
Using third-party websites carries minimal risk unless you're entering sensitive corporate passwords. For a home network, the risk of data interception when generating an image is virtually nonexistent, as you're only transmitting data to a public server for one second.
Once generated, the image can be saved to your computer and opened full-screen to be read by your phone. This method is useful because it allows you to generate codes for networks you haven't yet connected to but know the parameters for.
Creating Code Using the Command Prompt in Windows
For advanced users who prefer not to trust their passwords to third-party sites, there is a method for creating a QR code locally using the capabilities of the operating system itself. WindowsAlthough Windows doesn't support drawing images from the command line using standard tools, we can create a valid text template that the phone will recognize as a connection command.
The Wi-Fi connection string has a strictly defined format. You can create it manually or use a script. The format looks like this: WIFI:S:Network_Name;T:WPA;P:Password;;. Where S — this is the SSID (name), T — encryption type, and P - password.
WIFI:S:HomeNetwork;T:WPA;P:MyStrongPassword123;;By copying this string and sending it to your messenger or phone's notes, some modern QR code scanners and smartphone keyboards may recognize it as a connection command. However, to get a graphical image (a black-and-white square), the easiest way is to paste this string into any text editor, save the file, and use it as a data source for the generator described in the previous section, or use PowerShell with modules for generation.
Using the command line requires careful attention to syntax. One extra space or capitalization error can prevent the phone from reading data correctly.
Software solutions and utilities for PC
If you frequently work with multiple networks or are a system administrator, it makes sense to install specialized software. There are utilities that not only generate codes but also manage connection profiles. One popular free program is Wifi QR Code Generator or open source equivalents.
Such programs can often automatically read Wi-Fi profiles saved in Windows and offer to create a QR code for them with one click. This significantly speeds up the process compared to manually entering data into online services. Furthermore, local software ensures that your passwords don't leave your computer.
When choosing a program, pay attention to reviews and the developer's reputation. Security is a top priority, and installing questionable "image generator" software can lead to a malware infection.
- 📱 Locality: The data is processed on your PC without being sent to the Internet.
- 🔄 Batch processing: Ability to generate codes for dozens of networks simultaneously.
- 🎨 Customization: Possibility to add a company logo to the center of the QR code.
Nuances for macOS and Linux systems
Computer users Mac are in a better position thanks to the ecosystem AppleIf your Mac is connected to Wi-Fi and there's an iPhone or iPad nearby with the same Apple ID, the password will be transmitted automatically without any codes. However, if you need an image, macOS doesn't have a built-in "show QR code" feature for the current network.
To the owners MacBook You have to resort to the same methods: online generators or the terminal. In Linux, the situation is similar, but there are more options for scripting. Using console utilities like qrencode, you can generate a QR code directly in the terminal.
The command in Linux might look like this:
qrencode -t ansiutf8 "WIFI:S:MySSID;T:WPA;P:MyPassword;;"This will output the code directly to the terminal window, which can be read from the screen if the matrix is not too small, or saved to a file.
⚠️ Attention: Some laptop screens have low brightness or specific color rendering, which can make it difficult for your phone's camera to read the QR code. Increase your screen brightness to maximum.

Common problems and solutions
Even following the instructions, users may encounter difficulties. The phone camera may not focus on the monitor screen due to a moiré effect (ripples). In this case, try adjusting the distance between the phone and the screen or slightly zooming out on the QR code.
Another common problem is incorrect password formatting. If a password contains special characters, online generators may not process them correctly. Always double-check the generated code on one device before giving it to guests.
☑️ Checklist before code generation
It's also worth considering that some older smartphone models may not support the encryption standard used on your network, even with the correct QR code. In such cases, creating a guest network with more compatible parameters may help.
Is it possible to view the QR code of an already connected network in Windows 11?
The standard Windows 11 interface doesn't have this feature. However, if you have administrator rights, you can export the network profile to an XML file via the command line, find the cleartext password there, and use it to generate the code.
Will the QR code work if I hide the network name (SSID)?
Yes, the QR code will work, but the SSID line must contain the exact hidden network name. The phone will attempt to connect to it even if the network isn't visible in the general list of available networks.
What should I do if the camera doesn't see the code from the screen?
Try adjusting your monitor's brightness, removing glare, tilting your phone, or zooming in. Sometimes taking a screenshot of the code and sharing it from another device helps.
Is it dangerous to store a Wi-Fi QR code publicly?
Yes, anyone who sees the code will be able to connect to your network. Please do not post such images on public forums or social media without password-protecting your guest network.
