How to find out the WiFi password on a PC via cable

It's common for a desktop computer to be connected to a router via a twisted-pair cable and the wireless network password to be forgotten. This often happens after reinstalling the operating system or resetting the router, when the access key information is lost. Since a wired connection is already established, this gives you a direct advantage for recovering forgotten data without having to physically access the buttons on the device.

There are several proven ways to extract the secret key using the standard operating system tools or the router's web interface. Local area network Allows you to view connection parameters even without direct access to the wireless module. It's important to understand that access to the settings may be protected by a separate administrator login and password.

In this article, we'll cover methods for the Windows operating system, as it's the most common desktop operating system. You'll learn how to find saved keys through the graphical interface, use the command line for advanced searches, and access the router control panel. Windows 10 And Windows 11 have similar mechanisms for storing network profiles, which simplifies the process.

⚠️ Note: All methods described below only work if your computer is already connected to the router's network via a LAN cable or has previously saved a profile for this wireless network.

Finding a password through Windows network settings

The easiest and safest way is to use the operating system's built-in interface. If your PC has ever connected to this WiFi network (even if it's currently connected via a cable), Windows may have saved the profile. In modern OS versions, profile management is located in a separate settings menu.

First, you need to open the network management menu. Right-click the connection icon in the system tray or go to Control Panel. In the window that opens, find the "Network and Sharing Center" section. This displays the active connection, which in your case will be marked as Ethernet or "Local Area Connection".

The next step varies depending on the OS version, but the logic remains the same. You need to find the link to the wireless network properties. Even if the cable is physically connected to the LAN port, the system may display associated wireless profiles if they were previously saved. In the properties window, go to the "Security" tab.

This is where the "Network Security Key" field is located. By default, the characters are hidden behind asterisks. To view the password, you must select the "Show entered characters" checkbox. The system may request administrator privileges to perform this action. If prompted, confirm the action, and the hidden text will become readable.

• 🔑 Press Win + R, enter ncpa.cpl and press Enter to quickly access adapters.
• 🔑 Find your wireless connection in the list (even if it is not active right now).
• 🔑 Right-click and select "Status", then "Wireless Network Properties".

⚠️ Note: If your wireless adapter isn't listed or your network profile isn't saved, this method won't work. In this case, proceed to your router settings.

Using the command line to extract the key

For users who prefer console utilities, Windows provides a powerful tool netshThis method is often more efficient than the graphical interface, as it allows you to list all profiles ever saved, not just the active one. You must run the command prompt as administrator.

Enter the command netsh wlan show profiles to get a list of all networks. You'll see the profile names in the output. Find your network name in the list. If the list is empty, your computer has never connected directly to WiFi and hasn't saved the keys.

netsh wlan show profile name="Your_Network_Name" key=clear

After entering the command with the parameter key=clear The system will display detailed technical information about the profile. Scroll down to the "Security Settings" section. The "Key Contents" line will display the password you're looking for in clear text. This method works on all current versions of Windows.

The advantage of this method is that it doesn't require access to the graphical interface, which can malfunction if system files become corrupted. Furthermore, you can copy the profile name directly from the list to avoid typos. Command line Provides direct access to the network settings registry.

Logging into the router's web interface via a browser

If you don't have a WiFi profile saved on your computer, your only option is to check the router settings. Since you're connected via cable, you'll still be able to access the admin panel even if your wireless network is completely disabled or renamed. You'll need the default gateway address to log in.

You can find out the gateway address using the command ipconfig In the command line, find the "Default Gateway" line. This is usually an address like 192.168.0.1, 192.168.1.1, or 192.168.10.1. Enter this IP address into the browser's address bar.

After entering your username and password (often found on a sticker on the bottom of the device), the control panel will open. Interfaces vary by manufacturer, but the logic is the same. Find the "Wireless," "WiFi," or "Wireless Network" section. Inside, you'll find a subsection called "Security Settings."

What to do if the default password doesn't work?

If the default admin/admin password doesn't work, it means the password was changed during initial setup. Check to see if you wrote it down. If you can't remember it, you'll need to perform a hard reset by holding the reset button for 10-15 seconds. After this, the device will be accessible using the default data from the sticker, but you'll need to re-enter the internet settings.

Setting up wireless network security

In the router's web interface, it's important not only to view the password but also to check the encryption type. Modern standards require the use of WPA2-PSK or WPA3If you have the old WEP protocol installed, your network is vulnerable to hacking, and it's best to change the password immediately.

In the security section, you'll see the "Password (Pre-Shared Key)" field. Here, you can not only view the current key but also change it to a more complex one. It's recommended to use a combination of upper- and lower-case letters, numbers, and special characters, at least 12 characters long.

• 🛡️ Avoid using simple sequences (12345678, qwerty).
• 🛡️ Change your password at least once every six months to improve security.
• 🛡️ Disable the WPS function, as it is a vulnerability in network security.

After changing the password, all connected devices will lose connection and require re-authorization. This is normal security behavior. Make sure you save the new settings by clicking "Apply" or "Save."

⚠️ Note: Router interfaces are frequently updated. The menu layout may differ from what's described. Look for sections labeled "Wireless," "Security," "WLAN," or "Wi-Fi Settings."

Using third-party recovery utilities

There are specialized programs that can extract saved passwords from the Windows registry. One of the most well-known is WirelessKeyView from NirSoft. It requires no installation and works immediately after launch, displaying all saved keys in a convenient table.

Using these utilities requires administrator privileges. The program scans the system files where Windows stores network configurations. This is a quick solution if standard methods seem too complex or confusing.

However, be careful: many antivirus programs may classify such programs as potentially unwanted programs (RiskWare), as they have access to confidential information. Download software only from the developers' official websites.

Common problems and their solutions

When trying to view a password, users often encounter the error "Windows could not save the network settings" or access is denied. This could be due to an antivirus blocking the password or a lack of administrator rights. Try running your browser or command prompt as an administrator.

Another problem is an IP address conflict. If two devices with the same address are on the network, accessing the router's web interface may be difficult. In this case, try temporarily disconnecting the other devices or changing your PC's IP address to a static one within the same subnet.

If all else fails and you can't log into the router and there's no Windows profile, the only option left is a physical reset. Look for a small hole on the router with the inscription ResetPress it with a paperclip for 10-15 seconds while the power is on. The router will reboot to factory settings.

Questions and Answers (FAQ)

Is it possible to find out the password if the computer is only connected via cable and has never received WiFi?

Yes, this is possible, but only by logging into the router's web interface (via a browser). You can't view the password for someone else's network through Windows settings, even if the PC has never connected to it over the air.

What should I do if I forgot my router settings password (admin)?

If you changed your control panel password and forgot it, it's impossible to restore it without resetting the router. You'll have to perform a hard reset (factory reset) using the button on the router.

Is it safe to store passwords in Windows?

Windows stores passwords encrypted in the system registry. They can only be accessed with administrator rights. This is safe for the average user, but an attacker with administrator rights can easily steal them.

Why does the netsh command give the error "Network out of range"?

This error means you're trying to view the properties of a network to which your computer isn't currently connected or which has been removed from the list of known networks. Check the spelling of the profile name (SSID).
