How to Password Protect Wi-Fi on a Computer: Instructions for Routers and Windows

• Select WPA2-PSK or WPA3-PSK in the field Security Mode/Security mode.
• In the field Password/Password Enter a new password.
• Save settings (button Save, Apply or Apply).

The correct security mode (WPA2/WPA3) is specified|

The password is entered without spaces at the beginning/end|

The network name (SSID) does not contain personal information|

Cable connection is active (if you change the password remotely)-->

After saving, the router will reboot and all devices will be disconnected from Wi-Fi. Reconnect them with the new password.

⚠️ Attention: If after changing the password some devices (for example, smart light bulbs or printers) stopped connecting, check if they support the selected encryption type. For compatibility, temporarily return WPA2.

ASUS	router.asus.com	Wireless Network → General	WPA Pre-Shared Key
Keenetic	my.keenetic.net	Wi-Fi network → Access point	Network key
Zyxel	192.168.1.1	Wi-Fi Network → Access Point	Network key

⚠️ Attention: On routers from providers (for example, Rostelecom or Beeline) the path to the settings may differ. If you don't find the section Wi-Fi, check the tabs Home network or WLAN.

5. How to set a Wi-Fi password in Windows (if your router supports WPS)

If your router supports the technology WPS (Wi-Fi Protected Setup), you can change the password directly from Windows Control Panel, without accessing the web interface. This method doesn't work on all models, but it can save time.

1. Open Control Panel (Win + R → enter control → Enter).
2. Go to Network and Internet → Network and Sharing Center.
3. Click on the name of your Wi-Fi network (link next to Connections).
4. In the window that opens, select Wireless Network Properties → Security.
5. If the router supports WPS, a button will appear Change connection settingsClick it and enter a new password.

⚠️ Limitations of the method:

• 🔴 Works only if the router has enabled this function WPS (It is usually disabled by default due to vulnerabilities).
• 🔴 Not all router models support changing passwords through Windows.
• 🔴 The password will only change for the current connection, not for all devices on the network.
What is WPS and why is it better to disable it?

WPS (Wi-Fi Protected Setup) is a technology for quickly connecting devices to Wi-Fi without entering a password (for example, using a PIN code or a button on the router). However, due to vulnerabilities in the WPS protocol, it can be hacked in a few hours by brute-forcing the PIN code. If your router supports WPS, We recommend disabling it. in the security settings after changing the password.

6. What to do if you forgot your Wi-Fi password

If you don't remember your current Wi-Fi password, you can find out or reset in several ways:

6.1 View the password on a connected device (Windows)

1. Open Command line (Win + R → cmd).
2. Enter the command:

   netsh wlan show profiles

   Find your network name in the list.

3. Enter:

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

   The password will be in the line Key content.

6.2. Reset the router to factory settings

If you don't have access to the admin panel:

1. Find the button on your router Reset (usually recessed into the body).
2. Press and hold it 10-15 seconds (until the indicators blink).
3. The router will be reset to factory settings. The login and password will be reset to the default ones (see the sticker on the device).

⚠️ Attention: Resetting the router will remove all settings, including internet connection settings (if they were configured manually). After the reset, you may need to reconfigure PPPoE or other protocols from your ISP.

6.3. Find out the password through the provider's mobile application

Some providers (eg MTS, Beeline) offer mobile apps for managing your router. Log in to the app—it may display your current Wi-Fi password.

7. Common Mistakes When Setting Up a Wi-Fi Password

Even after changing the password, the network may remain vulnerable. Here common mistakes and how to avoid them:

• 🔹 Password too short: less 8 characters hacked in minutes. Use a minimum 12.
• 🔹 Using WEP: This encryption protocol is outdated and is being cracked 5-10 minutes. Choose WPA2 or WPA3.
• 🔹 Open network for guests: if you have it enabled Guest Wi-Fi without a password, disable it or password-protect it.
• 🔹 Standard router login/password: After setting up, change your login details for the control panel (for example, from admin/admin to unique ones).
• 🔹 Lack of firmware updates: Vulnerabilities in older firmware allow passwords to be bypassed. Update your router's firmware once a year. 6 months.

If your internet connection is lost or the speed has dropped after changing your password, check:

• 🔌 Is the cable from the provider connected to the router?
• 📶 Has the network name changed? (SSID) - some devices do not connect to "unknown" networks automatically.
• 🔄 Does the router require a reboot (sometimes settings are only applied after a manual reboot).

8. Additional security measures for Wi-Fi

A password is just the first step. To make your network truly secure, follow these recommendations:

• 🛡️ Disable remote control: Find the option in your router settings Remote Management and deactivate it.
• 📡 Hide SSID: In the Wi-Fi settings, enable the option Hide SSID (will hide the network name from outsiders).
• 🔄 MAC address filtering: Allow connection only to trusted devices (the list of MAC addresses is specified manually).
• 📊 Guest network: If you need access for friends, create a separate guest network with limited rights.
• 🔄 Regular updates: Check for new firmware for your router on the manufacturer's website.

For advanced users:

• 🔐 VLAN: Separate traffic between home and work devices at the network level.
• 🌐 VPN on a router: set up OpenVPN or WireGuard to encrypt all traffic.

⚠️ Attention: MAC address filtering isn't foolproof—MAC addresses can be spoofed. Use it as a supplemental measure, not as a replacement for a password.

FAQ: Frequently Asked Questions About Wi-Fi Passwords

Is it possible to set a Wi-Fi password without access to the router?

No. The password can only be set through the router's administrative panel. If you don't have access to the router (for example, if you rent it from your ISP), please contact technical support.

What password is impossible to hack?

There are no absolutely invulnerable passwords, but the most reliable one is a random combination of 16+ characters with letters, numbers, and special characters. Example: kL9#pQ2$mR4!vN7@xY1Use password generators to create such a combination.

Why don't some devices connect after changing the password?

Possible reasons:

• The device does not support the selected encryption type (WPA3 doesn't work on Windows 7 or old smartphones).
• The password contains characters that are not supported by the device (for example, Cyrillic or rare characters).
• The device has saved the old password in the network settings. Delete the network and reconnect.

Is it possible to set different passwords for 2.4 GHz and 5 GHz?

Yes, if your router supports separate settings for the two bands. The admin panel usually has separate tabs for Wi-Fi 2.4GHz And Wi-Fi 5GHzThis is convenient if you want to give guests access only to a slow network. 2.4 GHz, leaving 5 GHz for personal devices.

What should I do if my router doesn't save my new password?

Try the following:

1. Reboot your router (turn off the power on 30 seconds).
2. Reset to factory settings and set up from scratch.
3. Check if your antivirus or firewall is blocking the saving of settings.
4. Update your router firmware to the latest version.

If the problem persists, the router may be faulty - contact the service center.
