How to Change Your Wi-Fi Password on a Laptop: 3 Methods for Any OS

Changing your home Wi-Fi password from your laptop is a task that every user faces sooner or later. Reasons can vary, from a simple desire to increase security to suspicions that neighbors are using your internet without permission. But not everyone knows that The password is not changed in the laptop settings., and in the router's web interface, the device that distributes the signal.

In this article, we will look at three main ways to change your password depending on your operating system (Windows, macOS or Linux), we'll show you how to access your router settings even if you've forgotten your old password, and explain which security settings you should configure additionally. You'll also learn Why doesn't changing my password through the Windows Control Panel work? and what to do if the router does not save new settings.

Why can't I change my Wi-Fi password directly in Windows?

Many users mistakenly try to find the option to change the password in Windows Settings → Network & Internet or through the Network and Sharing Center. However, here you can only connect to an existing network or delete saved password - but not change it.

The thing is that the password is not stored on the laptop, but in memory router (router). The laptop only connects to the network using saved credentials. To change them, you need to go to router web interface — a dedicated control panel accessible through a browser. It's like trying to change the lock on your building's entrance hall with only the key to the apartment: the key (the password on the laptop) grants access, but doesn't control the lock (the router) itself.

⚠️ Attention: If you rent a router from a provider (for example, Rostelecom or MTS), some settings may be locked. In this case, you'll need to call support or use your provider's app to change your password.

The exception is when the laptop is used as access point (distributes Wi-Fi itself). Then the password is changed in the "Mobile Hotspot" settings (Settings → Network & Internet → Mobile Hotspot). But this is a separate scenario, which we will consider at the end of the article.

Method 1: Changing the password via the router's web interface (universal method)

This method works regardless of your laptop's operating system. You'll need:

• 🖥️ A laptop connected to the router via cable or Wi-Fi (if you know the current password).
• 🌐 Any browser (Chrome, Firefox, Edge).
• 📝 Login information for your router (usually found on a sticker on the device).

Step 1: Find Out Router IP address. Usually it is 192.168.0.1 or 192.168.1.1, but may vary depending on the model. You can find the address:

• 🔍 On the sticker on the bottom of the router (next to the default login/password).
• 🖱️ In Windows: open Command line (click Win + R, enter cmd) and run the command:

  ipconfig | findstr "Default Gateway"

  The address will be indicated in the "Default Gateway" line.

• 🍎 In macOS: open Terminal and enter:

  netstat -nr | grep default

Step 2: Enter the IP address in the browser's address bar. A login window will open. Enter your username and password (often the default admin/admin or admin/password). If the data is not suitable, try resetting the router to factory settings (button Reset on the back panel).

Make sure your laptop is connected to the router | Find the router's IP address (via a sticker or command) | Have your login/password ready (default or your own) | Open your browser in incognito mode (to avoid cache conflicts)

-->

Step 3. Find the Wi-Fi settings section. Depending on your router model, it may be called:

• 📡 Wireless / Wi-Fi / Wireless network
• 🔒 Security / Protection / Security
• ⚙️ Settings / Settings

Step 4. In the field Password, Key or Password Enter a new password. We recommend using:

• 🔢 Minimum 8 characters (preferably 12+).
• 🔤 A combination of letters (upper and lower case), numbers and symbols (!@#$%).
• 🚫 Avoid obvious combinations (12345678, qwerty, dates of birth).

Step 5. Save the changes (button Save, Apply or Apply). The router will reboot, and all devices will be disconnected from the network. Reconnect using the new password.

Method 2: Change your password through your provider's app (for subscribers of Rostelecom, MTS, Beeline, etc.)

Many internet providers offer their own mobile apps or web portals for managing your router. This is convenient if:

• 🔄 You forgot your login details for your router's web interface.
• 🔒 Your provider has blocked access to some settings.
• 📱 Want to manage your network from your smartphone or tablet.

Application examples:

Instructions for Rostelecom (similarly for other providers):

1. Download and install the application Rostelecom Personal Account.
2. Log in using your contract number or phone number.
3. Go to the section Services → Internet → Wi-Fi Settings.
4. In the field Password Enter a new one and save the changes.

⚠️ Note: Provider apps sometimes only allow basic password changes. For advanced settings (for example, changing the encryption type from WPA2 on WPA3) you will still need the router's web interface.

Method 3: Change your password via the command line (for advanced users)

This method is suitable if you have access to the router via Telnet or SSH (usually disabled by default). It requires technical knowledge and can render the router inoperable if an error occurs. Use it only if other methods are unavailable!

Step 1: Make sure that access is enabled on your router. TelnetTo do this:

1. Go to the router's web interface (as in Method 1).
2. Find the section Administration / Control → Remote Access / Remote access.
3. Turn on Telnet and save the settings.

Step 2: Connect to your router via Telnet:

• IN Windows: open Command line and enter:

  telnet 192.168.1.1

  (replace IP with your router's address).

• IN macOS/Linux: use Terminal with the same team.

Step 3. Log in (username/password are the same as for the web interface). Then enter the commands to change the password. Example for routers based on OpenWRT:

uci set wireless.@wifi-iface[0].key='new_password'
uci commit
wifi

For other firmware versions, the commands may differ—check your router's documentation for details.

What to do if the router does not respond to commands?

If after entering commands the router does not save changes or stops responding, try:

1. Restart it with the button Reset (hold for 10 seconds).

2. Connect via cable (Wi-Fi may be disabled after changes).

3. Check the command syntax - a typo in a parameter name will result in an error.

How to change your password if you forgot your old one

If you don't remember your current Wi-Fi password, there are two options:

Option 1: Reset the router to factory settings

• 🔄 Press and hold the button Reset on the back panel of the router (10–15 seconds).
• 🔌 Wait for the reboot (the indicators should flash).
• 📋 Your login and password will be reset to factory defaults (indicated on the sticker).

Cons: All settings (including network name, password, device priorities) will be lost.

Option 2: Find out the password using a laptop (if it is connected to the network)

• 🖥️ In Windows:
  1. Open Settings → Network and Internet → Wi-Fi.
  2. Click Managing known networks → select your network → Properties.
  3. In the field Network password The hidden text will be displayed. Click Show symbols.

🍎 In macOS:

1. Open Keychain Access utility (through Spotlight).
2. Find the name of your Wi-Fi network and double-click on it.
3. Check the box Show password and enter your Mac account password.

⚠️ Note: If your laptop has never connected to this network, or the password has been changed since the last connection, this method will not work. In this case, your only option is to reset the router.

Additional security settings after changing your password

Simply changing your password isn't enough to fully secure your network. We recommend setting up:

1. Encryption type

• 🔐 Use WPA3-Personal (if the router supports it).
• 🔄 If WPA3 no, please select WPA2-PSK (AES).
• ❌ Avoid outdated WEP And WPA - they are easy to hack.

2. Hiding the network name (SSID)

• 👁️ Disable the option in your router settings Broadcast SSID / Broadcast SSID.
• ⚠️ Disadvantage: You will have to manually enter the network name on new devices.

3. Filtering by MAC addresses

• 🔗 Allow connections only for known devices (their MAC addresses are listed in the network settings on each device).
• ⚠️ This is not a panacea - MAC addresses can be spoofed, but this will add an extra barrier.

4. Updating the router firmware

• 🔄 Check the section Firmware Update / Software update in the web interface.
• 🛡️ Regular updates patch vulnerabilities that hackers can exploit.
