It's quite common for smartphone owners to urgently need to access the internet but don't know or forget their wireless network password. Samsung are in a better position due to the advanced features of the operating system One UI and shells AndroidModern security and convenience algorithms allow you to bypass manual character entry by using other communication channels or already authorized devices.
There are several proven methods that don't require knowledge of the network's alphanumeric security combination. Some of them work if one device already has access to the access point, while others rely on physical interaction with the router. It's important to understand that hack completely It is impossible to legally access a closed network without at least one connected device or physical access to the router.
In this article, we'll explore the technical nuances of each method, examine their applicability in various scenarios, and assess their security level. You'll learn how to use the system's built-in tools, guest access features, and quick pairing technologies. This will allow you to effectively resolve network access issues at home or when visiting.
Using a QR code for quick authorization
The most civilized and modern way to connect a new device is to scan the QR code generated by the main device. If you or the network owner already has a phone Samsung (or any other smartphone based on Android 10 (and above) that has previously successfully connected to this Wi-Fi network, the process will take a few seconds. The system will automatically extract the necessary data and transfer it to the new device.
To implement this method, you need to unlock the main phone's screen and go to the settings menu. Find the section Connections or select the item directly Wi-FiIn the list of available networks, find the one you want to connect to and click the gear icon to the right of its name. In the network settings menu that opens, you'll see a button at the bottom of the screen. QR code.
⚠️ Note: The QR code generation function may not be available on very old firmware versions. One UI or for operator versions of software, where functionality has been reduced by the service provider.
After clicking, a graphic code will appear on the screen. You can show it to the new phone's camera. If the target device also has Samsung With the current version of the OS, you just need to bring the cameras close to each other - the system will work Bixby Vision or the built-in scanner, and the connection will occur automatically. Otherwise, you can take a screenshot of the code and open it through the standard Camera or Gallery app on the second device.
What should I do if the QR code button is not displayed?
If you don't see the code generation button, try updating your phone's software through the "Software Update" menu. On some models, this feature is hidden in the "More" menu (three dots in the corner) within the network settings.
This method is ideal for parties or meetings when you need to quickly let guests online without having to dictate a complex combination of characters. It eliminates manual entry errors and ensures the transmission of correct encrypted data.
- 📱 Open Wi-Fi settings on your already connected Samsung phone.
- 🔘 Click the gear next to your network name.
- 📸 Select the "QR code" option at the bottom of the screen.
- 📲 Scan the code with your new device's camera for instant login.
WPS technology: connection without entering data
Protocol WPS (Wi-Fi Protected Setup) was designed specifically to simplify connecting devices to wireless networks. It allows you to establish a connection by simply pressing a button on the router or using a PIN code, although PIN codes are considered less secure in today's environment. For owners Samsung This method remains one of the fastest if the router supports this function.
The process is as follows: on the router you need to find a physical button with a marking WPS or Push ButtonOn the phone Samsung you should go to the Wi-Fi settings, open the additional menu (often hidden under three dots or the “Advanced” button) and select the item WPSAfter activating the function on your smartphone, you need to press the button on the router within two minutes.
⚠️ Note: In newer versions of Android (starting with version 9), Google officially removed WPS support from the system due to security concerns. If you have a modern Samsung device, this method may not be available in software, and you'll have to look for alternatives.
If you can't find the button on your router, check the device's web interface. By accessing the router's control panel via a browser, you can find a software button for activating WPS. However, it's important to remember that permanently activating this protocol makes your network vulnerable to PIN bruteforce attacks, so it's recommended to disable this feature in the router's settings after connecting.
Despite its decline in popularity due to security holes, WPS remains a handy tool for home use with trusted devices. It's especially useful for connecting gadgets without a full keyboard, such as smart lamps or printers, although smartphones Samsung also support this protocol at the hardware level.
Smart View and Screen Sharing
Ecosystem Samsung offers a unique feature Smart View, which allows you to stream content from your smartphone to a TV or monitor. An interesting technical nuance is that when attempting to stream content to a Smart TV that's on a different Wi-Fi network (or not connected), the system may offer to use the phone as an access point or, conversely, help the TV connect to the phone's network.
While this isn't a direct method of "cracking" a password, it works as a bridge in smart home scenarios. If your TV Samsung Smart TV already connected to Wi-Fi, but the phone is not, you can try to initiate a connection through the app SmartThingsWhen a device is detected on the same local network (if the phone is connected via cable or via guest access without internet), the phone may request permission to use the TV's network settings.
A more common use case is when your phone is already connected to a network and you want to share that connection with other devices via a TV acting as a hub. However, for the direct purpose of connecting your phone to an unknown network, this method works indirectly: it allows you to access internet content on a large screen, even if your mobile data is limited.
It's important to note that for these features to work, all devices must be trusted and typically logged into the same account. This is part of the philosophy. seamless ecosystem, where the user does not have to worry about the technical details of connecting each gadget separately.
- 📺 Make sure your TV and Samsung phone are close together.
- 📲 Launch the SmartThings app on your mobile device.
- 🔗 Select your TV from the list of available devices.
- 📡 Follow the instructions to sync your network settings.
Guest network and automation via NFC
For those who frequently host guests or have many devices, creating a guest network is an excellent solution. Owners of routers that support NFC tags or special stickers can program them to connect automatically. Phone Samsung When brought close to such a tag, it reads the encrypted network profile and connects without asking for a password.
This method requires some preparation. You will need an NFC tag writing app (available in Google Play) and the tags themselves (inexpensive stickers). The app creates a task: when the tag is read, perform the "Connect to Wi-Fi" action, specifying the SSID and password. After recording, the tag is affixed to a visible location, such as a refrigerator or living room wall.
⚠️ Note: Writing a password to an NFC tag makes it accessible to anyone with an NFC-enabled smartphone and a reader app. Use this method only for guest networks with limited access to local resources.
The advantage of this approach is that guests don't need to explain anything. Simply say, "Place your phone on the Wi-Fi icon on the wall." It looks high-tech and eliminates the need for the host to dictate long passwords. Furthermore, the tag can be reprogrammed or deactivated at any time by simply changing the router settings.
☑️ Setting up an NFC tag for Wi-Fi
It's important to note that not all guests' phones may have an NFC module enabled. In that case, this method won't work, and you'll have to resort to a traditional QR code. However, for regular family members or colleagues, this is a very convenient option.
Comparison of connection methods
The optimal method depends on your specific situation, your router model, and your phone's operating system version. Below is a comparison table to help you navigate the available options and their features.
| Method | Necessary conditions | Security | Speed |
|---|---|---|---|
