In this article we will analyze all working methods for different operating systems and router models.

If your computer is Windows 10 or 11 If you've ever connected to this Wi-Fi network (even if you're currently connected via cable), the password can be retrieved from saved profiles. This method works even if Wi-Fi is currently disabled.

Instructions for Windows 10/11:

1. Open Control Panel (click Win + R, enter control and press Enter).
2. Go to the section Network and Internet → Network and Sharing Center.
3. Select on the left Managing wireless networks (Windows 10) or Changing adapter settings (Windows 11).
4. Find the name of your Wi-Fi network in the list (SSID), right-click on it and select Properties.
5. In the window that opens, go to the tab Security and check the box Show entered characters — the password will become visible in the field Network security key.

⚠️ Attention: If your network doesn't appear in the list of saved networks, your computer has never connected to it via Wi-Fi. In this case, proceed to the next methods.

Do you remember the network name (SSID)-->

Alternative way through command line (if the GUI does not work):

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

Replace NETWORK_NAME to the actual SSID your Wi-Fi. The password will be in the line Key content.

2. Extracting a password on macOS or Linux

For users MacBook or PC with Linux Password recovery methods are also available, but the algorithm differs from Windows. You'll need a terminal and superuser rights (sudo).

sudo cat /etc/NetworkManager/system-connections/"NETWORK_NAME" | grep psk=

The password will be after psk=. If used wpa_supplicant, the path to the file may differ.

What should I do if the terminal returns a "not found" error?

If the command returns an error, it means:

1) The computer has never connected to this network via Wi-Fi.

2) The network name is entered incorrectly (check the case!).

3) On macOS, you may need to first add the network in System Preferences → Network.

• 🔄 Reboot your router (unplug it for 30 seconds).
• 🌐 Try a different browser or clear your cache (Ctrl + Shift + Del).

Problem 2: There is no password field in the Wi-Fi settings

• 🔍 Make sure you are in the right section (look for Security, Wireless Security, WPA).
• 📋 On some routers the password is hidden - try viewing the source code of the page (Ctrl + U).

FAQ: Answers to frequently asked questions

Is it possible to find out the Wi-Fi password if the computer is connected via a wire, but has never been connected to this network over the air?

Yes, but only through router web interface (Method 3 in the article). If the computer hasn't connected to Wi-Fi, the password isn't saved in the Windows/macOS settings.

My Rostelecom router won't let me access the settings—it says "Access Denied." What should I do?

Possible reasons:

1. You are entering an incorrect IP address (check via ipconfig).
2. Your provider has blocked access to settings (please contact support).
3. The router is broken or requires a reset (button Reset).

How can I find out the password if I rented a router from Rostelecom and it doesn't have a sticker?

In this case:

1. Try the standard logins/passwords for your model (see the table in the article).
2. If this doesn't work, call Rostelecom support (8-800-100-08-00) and request login information.

Is it possible to find out the password from a phone if it is connected to this Wi-Fi?

Yes, on Android (with root rights) or iPhone There are ways (with jailbreak), but they're more complicated than on a PC. Without root/jailbreak, the password can only be seen if the phone was once connected to the router via cable (which is unlikely).

For Android without root, try the app WiFi Password Viewer (requires superuser rights).

What should I do if the internet doesn't work after resetting my router?

After the reset you need to:

1. Connect to the router via cable.
2. Login to the web interface (usually 192.168.1.1, login/password — admin/admin).
