How to find the Wi-Fi password on a computer with wired internet

It's quite common to have a computer connected via a cable but need to connect a new device to a wireless network. The user is physically connected to the router via a LAN port, but the Wi-Fi password has been forgotten or lost. It might seem that since there's no wireless connection on the PC itself, there's no way to find the key, but this is a misconception. Modern operating systems and routers store configuration data in administrator-accessible partitions.

There are several proven ways to restore access to wireless network data, even if your PC works exclusively through Ethernet cableYou can use built-in Windows tools, the command line, or the router's web interface. It's important to understand that most methods require administrator privileges due to network protocol security concerns.

In this article, we'll cover the technical nuances of each method in detail. We'll cover how to retrieve saved profiles from the system, how to access the router's control panel, and what to do if standard methods fail. The key requirement for most methods is that the computer and router must be on the same local network, which is what a wired connection provides.

Using the Windows Command Prompt

The fastest and most reliable way to find out your saved password is to use the built-in tool NetshThis utility allows you to manage network interfaces through the console. Even if the computer's Wi-Fi adapter is disabled or missing, the system can store profiles of previously connected networks in its registry, which can be accessed through code.

To get started, you need to launch the command prompt as an administrator. Right-click the Start menu and select the appropriate option, or type cmd in the search, then click "Run as administrator." First, we need to display a list of all saved Wi-Fi profiles that have ever been active on this device.

netsh wlan show profiles

In the list that appears, find the name of your wireless network (SSID). If you see the name you need, copy it exactly, taking into account the case of the letters. Next, enter the command to display detailed profile information, adding the key to display the security key in plaintext.

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

In the "Security settings" section, find the "Key Content" line. This is where the password you're looking for will be displayed. If you see an error message instead of the network name, this profile isn't saved in the system, and you'll need to use other methods.

Viewing via the Windows GUI

Even if the computer is connected via a cable, Windows 10 and 11 allow you to manage the settings of all network adapters through a single control center. This method is more intuitive for users who don't want to deal with code. However, it only works if a Wi-Fi module is physically or virtually present in the system, even if it's disabled.

To access settings, open the Network Connections control panel. This can be done by pressing the following key combination: Win + R and entering the command ncpa.cplIn the window that opens, you'll see your Ethernet adapter (connected) and possibly your Wi-Fi adapter (disconnected). Right-click the Wi-Fi icon and select "Status," then "Wireless Network Properties."

In the new window, go to the "Security" tab. There you'll see the "Network security key" field, hidden by asterisks. Check the "Show characters" box to reveal the password. This method directly accesses the Windows credential store.

• ✅ This method only works if the Wi-Fi driver is installed.
• ✅ Does not require entering complex commands.
• ✅ Allows you to copy the password immediately.

⚠️ Attention: If you have a desktop computer without a built-in Wi-Fi module or USB adapter, the "Security" tab for the wireless network may simply not be present. In this case, this method will not work.

Login to the router's web interface

The most universal method, which always works regardless of whether your computer has a Wi-Fi adapter, is to access the router's settings. Since you're connected via cable, you have direct access to the admin panel. This is where all your wireless network settings are stored, including the current password.

To log in, you need to know the gateway IP address. Open the command prompt and enter ipconfigFind the line "Default Gateway". This is usually the address 192.168.0.1 or 192.168.1.1Enter this address into the address bar of your browser.

After entering the address, the system will ask for your login and password. If you haven't changed them, they're listed on the sticker on the bottom of the router. Standard combinations are often admin/admin or admin/passwordOnce inside, look for the "Wireless" or "Wi-Fi" section.

Interfaces vary widely between manufacturers, but the logic is the same. Find the "Wireless Password," "WPA Pre-Shared Key," or "Wireless Network Password" field. Changing this field will automatically change the password for all devices.

Finding passwords on different router models

Navigating a router's menu can be confusing for a beginner. Manufacturers constantly change the layout of settings in their firmware. Below is a table to help you navigate where to find Wi-Fi security settings on popular router models.

Please note that modern dual-band routers (2.4 GHz and 5 GHz) may have separate settings. The password is often the same for both bands, but sometimes administrators set different keys. Check the settings for both frequency bands if they are displayed separately.

What if the interface is in English?

Use your browser's online translator (Google Translate) or search for "Wireless," "Security," "Password," or "Key." The menu structure is logical: first select the network type, then security.

Using third-party utilities

If Windows' built-in tools seem too complex, you can use specialized software. There are programs that scan saved profiles and display passwords in a convenient format. One of the most well-known tools is WirelessKeyView from NirSoft.

This utility doesn't require installation (it's portable), which is convenient. It instantly scans the WLAN database and displays a list of all networks with their security keys. However, it's important to keep security in mind: antivirus programs may flag such programs as potentially unwanted programs, as they use the same methods as hacking tools.

This type of software should only be used on trusted computers. Download programs only from the developers' official websites to avoid introducing viruses. For a one-time password review, this may be the simplest solution.

⚠️ Attention: Antivirus software may block password viewing tools from running. Before running them, temporarily disable protection or add the program to the exceptions list if you're sure of the file's source.

Resetting your router as a last resort

If none of these methods work, you don't remember the router admin password, and the default password doesn't work, your last option is a full reset. There's a small hole on the device's body with the inscription Reset or Restore.

Press the button inside the hole with a paperclip and hold it for about 10-15 seconds until the lights flash. The router will reboot to its factory default state. After this, the Wi-Fi password will be the one on the sticker on the bottom of the device.

This method is drastic, as you'll have to reconfigure your internet connection (enter your ISP login and password if you're using PPPoE or L2TP). Only use it if you're confident you can restore your internet connection settings.

Frequently Asked Questions (FAQ)

Is it possible to find out a Wi-Fi password if the computer doesn't have a Wi-Fi module at all?

Yes, you can. In this case, the only way to access the router's web interface is through a browser (using the gateway IP address). The command line and Windows system settings won't reveal the password, as there's no physical adapter and profiles may not be saved.

What should I do if the admin/admin password doesn't work to log into the router?

Most likely, the password was changed earlier during setup. Try finding it on the sticker (sometimes it says "Login/Password"). If you don't remember it, only the reset button will help. Reset on the device body.

Is it safe to save a password in Windows?

For a home PC, this is safe if you have a password for your Windows account. If someone else uses the computer, they can easily retrieve the saved keys via the command line, as described in the first section of this article.

Why does the command line say "Network not found in profile"?

This means that this computer has never connected directly to this Wi-Fi network. Windows doesn't store passwords for networks connected to other devices unless they're synced via the Microsoft cloud (which is rare for wired PCs).
