Many users asking how to access someone else's network are actually experiencing a loss of access to their own router or want to check the security of their own settings. Instead of searching for illegal hacking methods, it's better to focus on methods for restoring access to your own equipment and strengthening the security of your home network perimeter. This will not only allow you to regain control of the internet but also prevent unauthorized connection attempts.
Modern encryption standards such as WPA3 And WPA2-Personal, make brute-forcing passwords an extremely difficult and time-consuming process, requiring enormous computing power. Most "easy" methods for bypassing protection found online are either myths or exploit vulnerabilities in router firmware that hasn't been updated in a long time. Understanding how wireless protocols work helps you configure your equipment correctly and avoid situations where your neighbors could be using your traffic.
In this article, we'll explore legal methods for recovering forgotten passwords on Windows and macOS operating systems, as well as through your router's web interface. You'll learn how to check who's currently connected to your network and what steps to take to prevent unauthorized access. Data security begins with a responsible approach to hardware configuration and regular network infrastructure maintenance.
Password recovery via the Windows operating system
If you've previously connected to the desired network on a Windows computer, the operating system may have saved your credentials for automatic connection. This is the easiest and fastest way to find the access key, without requiring complex software or in-depth knowledge of network protocols. All you need is physical access to a device that's already authorized on the network.
To view the saved password, go to the Network and Sharing Panel. Right-click the Wi-Fi icon in the system tray and select "Network and Internet Settings," then go to "Network and Sharing Center." In the window that opens, click the name of your wireless network. A status window will appear, where you should select "Wireless Network Properties."
In the dialog box that opens, go to the "Security" tab. Here you'll see the "Network Security Key" field, the contents of which are hidden by asterisks. To display the password, check the "Show entered characters" box. The system may require administrator privileges to perform this operation. This is standard procedure. Windows 10 and Windows 11.
⚠️ Note: If the "Security" tab is missing or the "Show entered characters" button is inactive, the current user does not have sufficient rights or the network has been configured through group policies that restrict viewing of keys.
An alternative method involves using the command line, which can be useful if the graphical interface isn't working correctly. Open the command prompt as administrator and enter the command netsh wlan show profilesto see a list of all saved networks. Then use the command netsh wlan show profile name="Network_Name" key=clear, where the required password will be displayed in the "Key Content" field.
View your access key on macOS and mobile devices
Apple ecosystem users can also easily retrieve saved passwords thanks to iCloud Keychain syncing. In macOS Ventura and later, the process is even more intuitive. Open System Preferences, go to the Wi-Fi section, and find the desired network in the list of known networks. Next to the network name, you'll see a button with three dots or an information icon.
By clicking the information icon or selecting "Copy Password," the system will prompt you to confirm using Touch ID or your Mac account password. Once successfully authenticated, the password will be copied to the clipboard or displayed in a text field. This feature works thanks to encryption of keys at the system level, which guarantees data security even if there is physical access to the device.
A similar feature is now available on iOS devices (iPhone and iPad) running iOS 16 or later. Go to "Settings" → "Wi-Fi," tap the blue information icon next to the name of the network you're connected to or saved. Tap the "Password" field, which is hidden by dots. After verifying Face ID or Touch ID, the password will become visible and can be copied.
It's important to note that viewing saved passwords without root access on Android devices is only possible in the latest versions of the operating system (Android 10 and above). This is typically done by scanning a QR code to connect to another device, where the password may be displayed in text underneath the code. However, on older versions of Android, direct viewing of the key in the settings was blocked by manufacturers.
Login to the router's web interface to change settings
The router's web interface provides the most comprehensive control over the wireless network. It allows you to not only view the current password, but also completely change the encryption algorithm, filter devices by MAC address, and update the firmware. To log in, you need the gateway IP address, which is usually located on a sticker on the bottom of the router.
Standard login addresses are most often 192.168.0.1, 192.168.1.1 or 192.168.31.1Enter this address in your browser's address bar. If the page doesn't open, check your TCP/IP settings in the connection properties: the default gateway address will be listed there. To log in, you'll need the administrator username and password, which are often also listed on a sticker (admin/admin).
After successfully logging in, find the section responsible for your wireless network. It may be called "Wireless," "Wi-Fi," "Wireless Mode," or "WLAN." Within this section, look for the "Security" or "Security Settings" subsection. This is where you'll find the "Wireless Password" (Pre-Shared Key), "WPA Passphrase," or similar field.
| Router brand | Standard IP | Default login | Default password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Xiaomi | 192.168.31.1 | admin | specified during setup |
If the default credentials don't work, they may have been changed previously. In this case, the only solution is to reset the router to factory settings. To do this, locate the button on the powered-on device. Reset (often recessed into the case) and press it with a paperclip for 10-15 seconds until the indicators flash. After this, the router will reboot with factory passwords.

Analysis of connected devices and identification of neighbors
Even if you've changed your password, there's no guarantee that your network hasn't been previously connected to or that your neighbors aren't exploiting WPS vulnerabilities. The most reliable way to check this is to view the DHCP Client List in the router interface. This displays all devices currently receiving an IP address from your router.
The list usually includes the device name, its MAC address, and assigned IP address. Match familiar devices (phones, TVs, laptops) with the list. If you see a device with an unfamiliar name (e.g., Unknown, Android-xxxx (or the network card chip name) is cause for concern. Modern routers allow you to block devices directly from this list.
For a more in-depth analysis, specialized network scanners can be used, such as Fing or WireShark (for advanced users). They show not only connected devices but also the amount of traffic they consume. Sharp spikes in internet speed without your activity often indicate the presence of "extra" users downloading content or using your network for mining.
⚠️ Warning: MAC addresses can be spoofed, so relying solely on them to identify devices is not recommended. The best protection is a whitelist, which allows access only to known MAC addresses.
If you detect an intruder, immediately change your Wi-Fi password and encryption type. It's also recommended to disable WPS, as it's one of the most vulnerable entry points for attackers using PIN brute-force methods. After changing the password, all devices will be disconnected, and you'll have to re-enter the new key on each one.
Technical aspects of wireless network security
Wi-Fi security is built on encryption protocols. The current standards are WPA2 And WPA3The old WEP protocol was cracked over a decade ago and should not be used under any circumstances. WPA2 uses the AES algorithm, which is considered secure if the password is sufficiently complex. WPA3 adds additional protection against brute-force attacks.
Password length and complexity play a critical role. An 8-character password can be brute-forced relatively quickly using modern GPU clusters. It is recommended to use a password of at least 12-15 characters, including uppercase and lowercase letters, numbers, and special characters. Using dictionary words makes the network vulnerable to dictionary attacks.
Why is WPS dangerous?
The Wi-Fi Protected Setup (WPS) protocol was designed to simplify device connections, but it has a critical vulnerability in its PIN verification method. An attacker can brute-force an 8-digit PIN in a few hours, as verification occurs piecemeal. Once the PIN is obtained, the master network password is restored. It is recommended to completely disable WPS in your router settings.
Besides the password, hiding the SSID (network name) is important. While this isn't foolproof (a hidden network is easily detected by a sniffer), it reduces the visibility of your network to casual passersby. However, for a home network, properly setting up guest access is more important. A guest network isolates guest devices from your main local network, which may include NAS storage or a smart home system.
Regularly updating your router firmware is a must. Manufacturers release patches to fix security holes. Outdated router firmware may contain backdoors that allow for complete remote control. Check the "System Tools" or "Administration" sections for updates.
Legal aspects and ethics of using networks
Attempting to gain unauthorized access to computer information to which you are not authorized is a violation. In the Russian Federation, this is regulated by Article 272 of the Criminal Code ("Unauthorized access to computer information"). Even if the network is not password-protected (open), connecting to it without the owner's permission may be considered a violation, especially if this entails modification or blocking of information.
Using someone else's Wi-Fi for illegal activities (downloading pirated content, sending spam, or hacking) creates risks for the network owner. The router owner may be held liable, as their IP address will appear in the provider's and law enforcement's logs. This is why it's so important to protect your network from your neighbors.
From an ethical standpoint, using someone else's resources without payment and consent is improper. If you need internet, it's best to contact your provider or use mobile internet. There are also public Wi-Fi zones provided by cafes and municipalities where access is legal.
Is it possible to hack a neighbor's Wi-Fi from a smartphone?
In theory, there are Android apps that attempt to brute-force passwords or exploit WPS vulnerabilities. However, in practice, modern routers are protected against brute-force attacks (blocking after several unsuccessful attempts). Furthermore, such apps often contain viruses or collect personal user data. There are no legal and effective ways to hack a secure WPA2 network from a phone in a couple of minutes.
What should I do if I forgot my router password and resetting it doesn't help?
If resetting the device with the Reset button doesn't restore access (the administrator password has been changed and won't reset, or the firmware is corrupted), you may need to reflash the device via TFTP or a console cable. In some cases, holding the Reset button for more than 30 seconds while powering on helps. If all else fails, the router may need to be replaced.
Does the number of connected neighbors affect internet speed?
Yes, the wireless channel is shared between all active clients. If your neighbor is downloading large files or watching 4K videos, your speed will drop significantly, and your gaming ping will increase. Furthermore, channel congestion can lead to connection instability and constant disconnects.
