How to Change Your Wi-Fi Password on Your Computer: A Step-by-Step Guide

Forgot your home Wi-Fi password or want to update it for security? You can do this directly from your computer without using a smartphone or tablet. In this article, we'll cover in detail how to change your Wi-Fi password from a PC on Windows 10 or 11, as well as the specifics for popular router models. TP-Link, ASUS, Keenetic and others.

Changing your password doesn't require any special knowledge, but it's important to follow the instructions to maintain network access. We'll explain how to access your router settings, where to find the security section, and how to correctly set a new password. You'll also learn what to do if you can't access the control panel or the router won't save changes.

If you use Wi-Fi on other devices (smartphones, TVs, printers) in addition to your PC, you'll have to reconnect them after changing the password. Don't forget to write down the new password in a safe place!

What you need to know before changing your Wi-Fi password

Before changing your password, make sure your computer is connected to the router via cable or Wi-Fi. If you're not connected, you won't be able to access the settings. Also check:

• 🔌 Router power supply — the indicators should light steadily, without blinking (except for the activity indicator).
• 📡 Connection type - It is better to use a wired connection (LAN) to avoid connection interruption when changing the password.
• 🔐 Login details — the standard IP address, login, and administrator password are usually indicated on the router sticker.

If you've previously changed your login and password for accessing your router settings but have forgotten them, you'll need to reset the router to factory settings. To do this, press and hold the button. Reset (usually it is recessed into the case) for 10-15 seconds. After the reset, the login data will become standard (usually admin/admin or admin/empty password).

⚠️ Note: Resetting your router will erase all settings, including the network name (SSID), Wi-Fi password, and internet connection settings. A complete reconfiguration will be required.

If you're unsure of your router's model, check the device's casing or documentation. The control panel interface varies depending on the model, but the general process for changing the password remains the same.

How to access router settings via a computer

To change your Wi-Fi password, you first need to open your router's web interface. To do this:

1. Open any browser (Google Chrome, Mozilla Firefox, Microsoft Edge).
2. In the address bar, enter the router's IP address. This is usually:
   • 192.168.0.1 (For TP-Link, D-Link)
   • 192.168.1.1 (For ASUS, Keenetic, Zyxel)

Click EnterIf the address is correct, an authorization window will open.

Enter your login and password. By default, this is often admin for both fields.

If the IP address is not suitable, you can find it out using the Windows command line:

1. Click Win + R, enter cmd and press Enter.
2. Enter the command:

   ipconfig

3. Find the line Main gateway - this is the IP address of your router.

⚠️ Attention: If you get the error "Page unavailable" when trying to log in, check your connection to the router (the cable must be firmly inserted into the port LAN, and not WAN). Also try disabling the VPN or proxy in your browser.

After successfully logging in, you'll see your router's control panel. The interface may vary depending on the model, but the section for changing the Wi-Fi password is usually called Wireless, Wi-Fi, Wireless network or Security.

Step-by-step instructions: how to change your Wi-Fi password

Now let's move on to changing the password. We'll look at the process using popular router models as an example. If your model is different, look for similar sections in the menu.

For routers TP-Link

In the control panel:

1. Go to the section Basic → Wireless (or Wireless mode).
2. In the field Wireless Password (or PSK password) enter a new password.
3. Select encryption type WPA2-PSK (recommended for safety).
4. Click Save (Save).

For routers ASUS

In the interface ASUS:

1. Open Wireless network in the left menu.
2. Tab General → field WPA Pre-Shared Key.
3. Enter a new password (minimum 8 characters).
4. Click Apply.

For routers Keenetic

In the web interface Keenetic:

1. Go to Wi-Fi network → Security.
2. In the field Network key Please enter a new password.
3. Select WPA2-PSK as an authentication method.
4. Save the changes.

After changing the password, the router may reboot (this is normal). All devices connected to the Wi-Fi network will be disconnected and will require you to re-enter the password.

The new password contains at least 8 characters.

WPA2-PSK encryption is used (not WEP!)

The network name (SSID) has not changed accidentally

The connection to the router is stable (the cable is not disconnected) -->

How to create a strong Wi-Fi password

A weak password can lead to your network being hacked. To protect your Wi-Fi from unauthorized access, follow these recommendations:

• 🔒 Use at least 12 characters (better 15-20).
• 📌 Turn it on uppercase and lowercase letters, numbers and symbols (!@#$%).
• 🚫 Avoid obvious combinations: birth dates, names, dictionary words, sequences (12345678, qwerty).
• 🔄 Don't use the same password for Wi-Fi and other services (email, social networks).

Examples of strong passwords:

• K0ff3e$tr0ng!WiF1
• S3cur3_P@$$w0rd_2026
• MyD0gL0v3s$W1F1!

If you are afraid of forgetting a complex password, write it down password manager (For example, KeePass, Bitwarden) or on paper, stored in a safe place. Do not save the password in clear text on your computer or in cloud services!

What to do if you can't change your password

Sometimes errors occur when trying to change your password. Let's look at common issues and their solutions:

If your router constantly reboots or doesn't provide internet access after changing your password, try:

1. Disconnect it from the power supply for 30 seconds, then turn it on again.
2. Check if the new password conflicts with symbols (some routers do not support Cyrillic or special characters).
3. Update firmware via section System Tools → Firmware Upgrade.

⚠️ Important: If your router stops working after updating the firmware, try rolling it back to the previous version or contact the manufacturer's support. Do not interrupt the update process!

How to update your Wi-Fi password on all your devices

After changing the router password, all previously connected devices (laptops, smartphones, TVs) will lose network access. To restore the connection:

• 📱 On Android: go to Settings → Wi-Fi, select your network, click Forget, then reconnect with the new password.
• 🍎 On iPhone/iPad: Settings → Wi-Fi, tap on the network, select Forget this network, then enter the new password.
• 💻 On Windows: Click on the Wi-Fi icon in the tray → Managing known networks → select network → Forget. Then reconnect.
• 📺 On Smart TV: Go to network settings, delete the saved network and connect with a new password.

If you have devices without a screen (such as printers or smart bulbs), you'll need to reconnect them via WPS or reconfigure them. This usually requires pressing the WPS button on the router and then allowing the device to search for the network for 2 minutes.

To simplify the process, you can temporarily reset the old password, connect all devices, and then change it back to the new one. However, this reduces network security.

Additional Wi-Fi security settings

In addition to changing your password, it is recommended to check other security settings:

• 🔄 Hiding the network name (SSID): in the router settings you can disable the network name broadcast (Hide SSID). This will make it less visible to strangers, but you will have to enter the network name manually on new devices.
• 🛡️ MAC address filtering: Allow connections only to trusted devices using their MAC addresses. However, this isn't a panacea—MAC addresses can be spoofed.
• 🕒 Wi-Fi operating hours: Set up automatic network shutdown at night (for example, from 12:00 AM to 6:00 AM). This will improve security and reduce load.
• 📡 Guest network: Create a separate network for guests with limited access to local resources.

To enable a guest network on a router TP-Link:

1. Go to Guest Network.
2. Activate Enable Guest Network.
3. Set a name and password for the guest network.
4. Limit speed or access time if necessary.

⚠️ Warning: Some features (such as MAC address filtering) may slow down your network or cause problems connecting new devices. Use them only when necessary.

How to find out the MAC address of a device?

On Windows: Open a command prompt and type ipconfig /all — The MAC address is specified in the line Physical address.

On Android: Settings → About phone → General information → Wi-Fi MAC address.

On iOS: Settings → General → About → Wi-Fi Address.

FAQ: Frequently asked questions about changing your Wi-Fi password

Is it possible to change the Wi-Fi password using a phone instead of a computer?

Yes, the process is similar. Open a browser on your smartphone, enter the router's IP address, and follow the same steps. However, it's more convenient to use a wired connection on your phone (via a USB cable with an Ethernet adapter) to avoid connection interruptions when changing the password.

What should I do if I lose internet access after changing my password?

Check:

• Is the provider's cable connected to the port? WAN router.
• Are your internet connection settings (PPPoE, DHCP, etc.) incorrect?
• Is your antivirus or firewall blocking network access?

If the problem persists, try rebooting your router or reverting to the old settings.

What password is impossible to hack?

There are no absolutely hack-proof passwords, but the most reliable password is:

• Long (20+ characters).
• Random (generated by password manager).
• Contains letters of different cases, numbers and symbols.
• Is not a word or phrase.

Example: 7x!K9@qL2#pM5$vN1&.

Should I change my Wi-Fi password regularly?

It is recommended to update your password every 3-6 months, especially if:

• Outsiders (guests, neighbors) connected to your network.
• You have noticed suspicious activity (slow internet for no apparent reason).
• Your other accounts (email, social networks) have been hacked.

Also, change the password after purchasing a new router—factory settings are often known to hackers.

Is it possible to recover a forgotten Wi-Fi password without resetting the router?

If you're connected to the network on a Windows computer, you can view your saved password:

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Click on your network name → Wireless network properties → Security.
3. Check the box Show entered characters — the password will become visible.
