How to find the Wi-Fi password for a PC connected via cable: a step-by-step guide

Are you connected to your router via Ethernet, but don't know the Wi-Fi password for the same network? This situation often arises when your ISP, neighbor, or office colleague set up your internet connection, and you suddenly need to connect your smartphone, tablet, or laptop over the air. Luckily, you can find the password directly from your computer, even if it's not directly connected to Wi-Fi.

In this article we will look at 5 proven methodsHow to retrieve a saved wireless network password on Windows 10/11 if the PC is connected to the router via cable. All methods work without installing third-party software (with one exception) and don't require access to the router's web interface. You'll also learn why some methods may not work and how to overcome common errors.

Why can a Wi-Fi password be found via a cable connection?

When a computer is connected to a router via Ethernet, it automatically becomes part of the local network. This means:

• 🔌 Windows has access to the settings of all network devices on this network, including the router itself (if remote access is not blocked).
• 📡 Wi-Fi adapter drivers can store data about previously connected networks - even if you are currently using a cable.
• 🔐 The system caches passwords from Wi-Fi in a secure storage (if you ever connected to this network over the air).

It is important to understand the difference between the two scenarios:

If your computer has ever connected to this Wi-Fi network, your chances of success are close to 100%. Otherwise, you'll have to use workarounds—we'll cover those, too.

Method 1: View saved networks in Windows settings

The easiest method is if your PC has connected to this Wi-Fi network before. Windows stores all wireless network passwords in Network Control CenterHere's how to extract them:

1. Click Win + R, enter ncpa.cpl and press Enter.
2. In the window that opens, find the icon Wireless network (Wi-Fi), right-click on it and select State.
3. Click the button Wireless network properties, then go to the tab Security.
4. Check the box Show entered characters — in the field Network security key a password will appear.

If the Wi-Fi icon is missing from the list of adapters or is disabled:

⚠️ Attention: This means that the wireless adapter driver is not installed or is disabled in Device Manager. Install the driver from the laptop/motherboard manufacturer's website (for Intel, Realtek, Broadcom and others).

This method only works if:

• 🖥️ Computer connected at least once to this Wi-Fi.
• 🔄 The network was not removed from the list of saved ones (for example, through Forget the network).
• 🔒 You have administrator rights (to view the password).

Method 2: Command Line (for advanced users)

If the GUI does not show the password, try to extract it through command lineThis method works even if the Wi-Fi adapter is currently disabled:

netsh wlan show profiles

This command will list all saved Wi-Fi networks. Find the name of the network you need (for example, TP-Link_1234) and run:

netsh wlan show profile name="TP-Link_1234" key=clear

Find the line in the results Key content — this is the password. If the command returned an error Profile not found, Means:

• 📛 The network has been removed from the system (click Forget in Wi-Fi settings).
• 🔧 The profile is corrupted (try the PowerShell method below).
• 🛡️ You don't have administrator rights (run the command prompt as one).

Critical detail: if the network name contains spaces or Cyrillic characters, wrap it in quotation marks: name="My Wi-Fi Network". Otherwise the command will not work.

Method 3: PowerShell - Alternative for Windows 10/11

PowerShell — a more powerful tool than the command line. It can extract passwords even if standard methods fail. Run:

(netsh wlan show profiles) | Select-String "\:(.+)$" | %{$name=$_.Matches.Groups[1].Value.Trim(); $_} | %{(netsh wlan show profile name="$name" key=clear)} | Select-String "Key contents\W+\:(.+)$" | %{$pass=$_.Matches.Groups[1].Value.Trim(); [PSCustomObject]@{PROFILE=$name;PASSWORD=$pass}} | Format-Table -AutoSize

This command:

1. Gets a list of all saved Wi-Fi networks.
2. Extracts the password for each network.
3. Displays a table of network names (PROFILE) and passwords (PASSWORD).

If the script returned an empty table:

⚠️ Attention: In some Windows builds (especially pirated ones), the service WLAN AutoConfig It may be disabled or damaged. Check its status with the command sc query WlanSvc - if the condition is not RUNNING, start the service as described above.

For convenience, you can save the command to a file. get-wifi.ps1 and run it with the right click → Run with PowerShell.

Method 4: Router web interface (if IP and login are known)

If the previous methods didn't work (for example, the PC has never connected to this Wi-Fi), the only option left is go to the router settings via a browser. To do this:

1. Find out your router's IP address:
   • 🖥️ On Windows: ipconfig → find the line Main gateway (usually 192.168.0.1 or 192.168.1.1).
   • 📱 On Android: Settings → Wi-Fi → [your network] → Learn more.

Typical login details for popular router brands:

If the standard login/password does not work:

• 🔍 Check the sticker on the bottom of the router - sometimes it contains specific information.
• 📞 Call your ISP - they may know the password (especially if they provided you with the router).
• 🔄 Reset the router using the button Reset (hold for 10 seconds) - the factory password will return.

⚠️ Attention: Resetting the router (Reset) will reset all settings to factory defaults, including the Wi-Fi password. After this, you'll have to set up your internet connection again (you may need help from your provider).

Method 5: Third-party programs (if nothing helps)

If all the above methods fail, you can use specialized utilities. They scan the system for saved passwords and display them in a convenient format. Popular programs:

• 🔓 WirelessKeyView (from NirSoft) - free, does not require installation, shows all saved Wi-Fi passwords.
• 🛡️ WiFi Password Revealer - simple interface, export passwords to a file.
• 🔍 Magical Jelly Bean WiFi Password Revealer — works even on older versions of Windows.

How to use WirelessKeyView:

1. Download the program from official website (check the file for viruses).
2. Unzip and run WirelessKeyView.exe (as administrator).
3. Find the required network in the table - the password will be in the column Key (Ascii).

Warnings when using third-party programs:

⚠️ Attention:

• Do not download such utilities from torrents or unverified sites—they may contain viruses.
• Your antivirus may block their operation (add the program to the exceptions).
• On corporate PCs, running such software may violate security policy.

If the program did not show the password, it means:

• 🗑️ The network profile has been removed from the system.
• 🔒 Windows stores the password in encrypted form, which the program cannot decrypt (rare, but it happens).
• 🛡️ The PC has data encryption software installed (for example, BitLocker or corporate solutions).

Common mistakes and how to avoid them

When trying to find a Wi-Fi password, users often encounter common problems. Here are the most common ones and their solutions:

If you encounter an error not described above:

• 🔍 Read the error text carefully—it often contains a hint.
• 📋 Write down the exact text and search for a solution on forums (for example, Microsoft Community or 4PDA).
• 🛠️ Check the integrity of system files with the command sfc /scannow.

Safety: How to avoid problems

Extracting Wi-Fi passwords is a harmless procedure if you do it on in his own equipment. However, there are a few nuances worth keeping in mind:

• 🚫 Illegally attempting to obtain a password from someone else's network without the owner's permission (this qualifies as unauthorized access under Article 272 of the Criminal Code of the Russian Federation).
• 🔒 If you are a network administrator in an office, store passwords in a secure location (for example, in KeePass or Bitwarden).
• 📴 Don't share your Wi-Fi password with third parties—this could lead to network congestion or unauthorized access to local resources.
• 🔄 Change your Wi-Fi password regularly (every 3-6 months), especially if guests connect to the network.

If you suspect your Wi-Fi is being used without permission:

1. Go to the router's web interface and check the list of connected devices (section DHCP Clients or Devices).
2. Change your Wi-Fi password to a more complex one (at least 12 characters with numbers and special characters).
3. Enable MAC address filtering (although this is not a panacea - MAC addresses can be spoofed).
4. Disable the feature WPS - it is vulnerable to brute force attacks.

To generate a strong password, you can use:

• 🎲 Built-in generator in KeePass or 1Password.
• 🔢 Online services (for example, Passwords Generator), but do not use them on public PCs.
• 📌 Mnemonic phrases: Cat! Ate 5 Mice @UnderTheBed.

⚠️ Attention: Some routers (especially those from ISPs) may have their Wi-Fi password tied to the device's serial number. In this case, changing the password in the web interface will disconnect the connection, requiring you to reconfigure the router.
