How to Create a Private Wi-Fi Network on Your Computer: 3 Proven Methods

An open Wi-Fi network is like an unlocked door to your home. It can be used not only by neighbors looking to "catch some free internet," but also by hackers who can intercept personal data, infect devices with viruses, or use your IP address for illegal activities. Closed Wi-Fi With a strong password and proper security settings, this is the minimum every user should have in 2026.

Many people mistakenly believe that setting up a closed network requires in-depth technical knowledge or calling a professional. In reality, the entire process takes no more than 10 minutes and boils down to three key steps: changing the network name (SSID), setting a complex password and choosing the right encryption type. no need to go to the command line or install additional software - everything is done through the standard settings Windows and the router's web interface.

In this article, we will look at three ways to disable Wi-Fi: through the router control panel (the most reliable method), using built-in tools Windows 10/11, as well as an alternative option for those sharing internet from their computer. We'll also cover common mistakes that can ruin all your network security efforts.

Why Open Wi-Fi Is Dangerous: 5 Real Threats

According to data Kaspersky for 2026, 68% of home network hacks These occur through vulnerabilities in open or poorly secured access points. And the victims aren't just users storing important documents on their PCs, but also those simply browsing social media. Here's what can happen if your Wi-Fi is left unprotected:

🔴 Traffic theftNeighbors or passersby can connect to your network, causing your internet speed to drop by 2-3 times. This is especially noticeable when watching videos. 4K or online games, where every megabit counts.

🔴 Man-in-the-middle attacks (MITM). The attacker intercepts data transmitted between your device and websites (logins, passwords, banking details). For example, when logging into Sberbank Online or VKontakte through an unsecured network.

🔴 Spread of virusesThrough open Wi-Fi, hackers can download malware onto your computer that will steal files or encrypt them for subsequent blackmail (as is the case with ransomware). WannaCry).

🔴 Using your IP for illegal activitiesIf someone downloads pirated content or commits a cyberattack through your network, you, as the connection owner, will be held liable.

🔴 Access to local devicesSmart speakers, CCTV cameras, or printers may be on the same network as you. Attackers can access them and use them for their own purposes (for example, eavesdropping through the speaker's microphone).

⚠️ AttentionIf you live in an apartment building, your public Wi-Fi may automatically connect to your neighbors' devices (smartphones, laptops), even if they don't know the password. This is due to the feature Auto-Connect in modern gadgets.

To check if anyone is connected to your network, go to your router settings (usually at 192.168.0.1 or 192.168.1.1) and look at the list of devices in the section DHCP Clients or Connected DevicesIf there are unknown people there MAC addresses, the network is already compromised.

📊 How often do you check the list of connected devices in your router?
Never
Once every six months
Only if the internet is slow
Regularly (once a month)

Method 1: Disable Wi-Fi through your router settings (the most reliable method)

This method works for any routers (TP-Link, ASUS, Keenetic, MikroTik etc.) and guarantees maximum protection. You will need access to the device's web interface.

📌 Step 1: Login to the Control Panel

  1. Connect your computer to the router via cable (LAN) or via Wi-Fi.
  2. Open your browser and type in the address bar 192.168.0.1 or 192.168.1.1 (the exact address is indicated on the sticker on the back of the router).
  3. Enter your login and password (by default this is often admin/admin or admin/password).

📌 Step 2. Change the network name (SSID)

Find the section in the menu Wireless (or Wireless network, Wi-Fi). In the field SSID Enter a new network name. Do not use personal information (For example, Ivanov_kv5), as this makes things easier for hackers. It's better to come up with a neutral name, for example Starlink_742.

📌 Step 3: Set the password and encryption type

In this same section, find the following fields:

  • 🔒 Security Mode (or Security) - select WPA2-PSK (or WPA3-PSK, if the router supports it). WEP encryption is not secure. and can be hacked in a few minutes!
  • 🔑 Password (or Password) - come up with a combination of 12+ characters, including capital letters, numbers and special characters (for example, T7#pL9@mK2$vQ!).

📌 Step 4: Save and Reload

Click Save (Save) and wait for the router to reboot. After this, all devices will be disconnected from the network, and you will have to reconnect using a new password.

⚠️ Attention: If the Internet connection is lost after saving the settings, check if the parameters have been reset. IP or DNS in the connection settings on your computer. Sometimes routers require manual input. DNS from Google (8.8.8.8) or Cloudflare (1.1.1.1).

Is the encryption type specified correctly (WPA2/WPA3)?

Password length must be at least 12 characters|

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

WPS is disabled in the settings (if not used)-->

Method 2: Setting up a closed Wi-Fi network via Windows 10/11 (if the router is unavailable)

This method is suitable if you do not have access to a router (for example, you are connected to a public network and want to create your own secure access point). Limitation: This Wi-Fi will only work when the computer is turned on.

📌 Step 1: Run Command Prompt as Administrator

Click Win + X and select Terminal (Administrator) or Command Prompt (Administrator).

📌 Step 2: Create a secure network

Enter the command (replace MyWiFi And MyPass123! to your network name and password): 

netsh wlan set hostednetwork mode=allow ssid=MyWiFi key=MyPass123! keyUsage=persistent

Where:

  • ssid=MyWiFi — network name (no spaces!).
  • key=MyPass123! — password (minimum 8 characters).

📌 Step 3. Launching the network

Enter the command: 

netsh wlan start hostednetwork

If a message appears The hosted network is launched, everything went well.

📌 Step 4: Enabling Internet Sharing

  1. Open Control Panel → Network and Sharing Center.
  2. Click Changing adapter settings.
  3. Find your primary connection (eg. Ethernet or Wireless network), right-click and select Properties.
  4. Go to the tab Access and check the box Allow other network users to share your Internet connection.
  5. In the drop-down list, select the network you created (it will be called Local Area Connection* X).

⚠️ ImportantAfter you restart your computer, the hosted network will be disabled. To restart it, repeat the command. netsh wlan start hostednetwork.

Method 3: Disabling Wi-Fi via the router's mobile app (for modern models)

Manufacturers of the type TP-Link, ASUS And Xiaomi release mobile applications for managing routers (Tether, ASUS Router, Mi WiFi). This is convenient if you are setting up the network from a smartphone or tablet.

📌 Step 1: Install the app

Download the official app for your router model from App Store or Google Play. Do not use third-party programs - they may contain viruses.

📌 Step 2: Connecting to the Router

Launch the app and follow the connection instructions. This usually requires scanning QR code on the router sticker or enter it MAC address.

📌 Step 3: Security settings

In the application menu, find the section Wi-Fi or Wireless network And:

  • 🔄 Change the network name (SSID).
  • 🔐 Select encryption type WPA2-PSK or WPA3-PSK.
  • 🔑 Set a password (the app usually checks its strength in real time).
  • 🚫 Turn off the feature WPS (if it exists) is a vulnerability that hackers exploit.

📌 Step 4. Additional security measures

In some applications (eg. ASUS Router) Can:

  • 🕒 Set a Wi-Fi schedule (for example, turn off the network at night).
  • 📱 Restrict access for specific devices by MAC address.
  • 🛡️ Enable built-in firewall or antivirus protection DDoS attacks.
⚠️ AttentionMobile apps may not support all router features. For fine-tuning (such as changing the Wi-Fi channel or signal strength), it's best to use the web interface.
How do I reset my router to factory settings if I forgot my password?

Find the button on the back of the router. Reset (It's usually recessed into the case.) Press it with a paperclip and hold it for 10-15 seconds until the lights start flashing. After this, the router will reboot, and you'll be able to log in with the factory username and password (indicated on the sticker).

Common Mistakes When Closing Wi-Fi (and How to Avoid Them)

Even experienced users sometimes make mistakes that can ruin all their network security efforts. Here are the most common ones:

| Error | Consequences | How to fix |

|--------------------------|------------------------------------------|--------------------------------------------|

| Usage WEP-encryption | Password can be cracked in 5 minutes | Switch to WPA2-PSK or WPA3-PSK |

| Short password (less than 8 characters) | Easily cracked by brute force | Set a password ≥12 characters long with letters, numbers, and special characters |

| Enabled WPS | Vulnerability to attacks Reaver | Disable WPS in the router settings |

| Standard network name (TP-Link_123) | Makes it easier to identify your router model | Come up with a unique name without mentioning the brand |

| No firmware updates | Vulnerabilities in the old software version | Update the router firmware via the web interface |

🔹 Mistake #6: Placing the router next to a window

If the router is located close to a window, the signal will be well received outdoors, making the task easier for hackers. Optimal location - in the center of the apartment, away from the outer walls.

🔹 Mistake #7: Using the same password for Wi-Fi and the router admin panel

If an attacker cracks your Wi-Fi password, they can access your router's settings and change them. Always use different passwords to connect to the network and access the web interface. WPA3-PSK + password length 16+ characters + disabled WPS + hidden network name (Hide SSID).-->

How to check if Wi-Fi is really closed

Setting a password is only half the battle. You need to make sure the network is truly secure. Here's how:

🔍 Check #1: Scan the network with third-party devices

Take a smartphone or laptop that hasn't connected to your Wi-Fi before and try to find your network in the list of available ones. If it:

  • 🔴 Visible without entering a password - Means, SSID It is not hidden and can be seen by everyone.
  • 🟢 Not visible at all - you have enabled the function Hide SSID (hiding the network name).
  • 🟡 Visible, but requires a password — basic protection works, but the network name can be eavesdropped on by special programs.

🔍 Test #2: Vulnerability Test

Use free tools to check your network security:

  • 🛡️ Wireshark — analyzes traffic and identifies suspicious activity.
  • 🔓 Wi-Fi Inspector (from Kaspersky) - scans the network for vulnerabilities.
  • 📡 Fing (mobile app) - shows all connected devices and their MAC addresses.

🔍 Check #3: Monitoring Connected Devices

Regularly access your router settings (section DHCP Clients or Connected Devices) and check the list of devices against your gadgets. If you find an unknown one MAC address, change your Wi-Fi password immediately.

💡 Advice: In some routers (for example, Keenetic) you can enable notifications about new connections by email or in the mobile app.

Additional protective measures: for the paranoid (and not only)

If you store important data on your computer or just want maximum protection, use these tips:

🔐 1. Hiding the network name (Hide SSID)

Find the option in your router settings Hide SSID or Hide networkAfter this, your Wi-Fi will not be displayed in the list of available networks, and you will only be able to connect to it manually, knowing the name (SSID) and password.

🔄 2. Regularly change your password

Change your Wi-Fi password every 3-6 monthsThis will make things more difficult for those who have previously connected to your network (for example, guests or neighbors to whom you temporarily granted access).

📵 3. Disable Wi-Fi while you are away

If you're going on vacation or leaving home for an extended period, disable Wi-Fi in your router settings. This will prevent connection attempts while you're away.

🛡️ 4. Using a guest network

Modern routers support the function guest Wi-FiThis is a separate network with limited access to local devices (printers, network drives). Give guests a password only for the guest network.

🌐 5. Setting up MAC filtering

You can specify it in your router settings MAC addresses devices that are allowed to connect to the network. All others will be blocked. Minus: If you buy a new gadget, you will have to add it manually.

⚠️ Attention: MAC addresses can be counterfeited, so this method does not provide 100% protection, but it makes the task more difficult for attackers.

🔗 6. Using a VPN on a router

Some routers (eg. ASUS RT-AX88U or Keenetic) support installation VPN At the network level. This means all traffic passing through Wi-Fi will be automatically encrypted. Setting this up requires a separate article, but the results are worth it.

How do I find out my device's MAC address?

On Windows:

  1. Click Win + R, enter cmd and press Enter.
  2. Enter the command ipconfig /all.
  3. Find the line Physical address - that's it MAC address.
On Android/iOS:
  1. Open Wi-Fi settings.
  2. Click on your network → find the item MAC address or Device address.

FAQ: Answers to Frequently Asked Questions

Is it possible to close Wi-Fi without access to the router?

Yes, but only if you create a new access point via a computer (see Method 2 (See the article). This is a temporary solution, as the network will only work when the PC is turned on. For full protection, you need to configure the router itself.

What is the most secure Wi-Fi password?

The ideal password in 2026:

  • 🔹 Length: 16+ characters.
  • 🔹 Combination: uppercase and lowercase letters (A-z), numbers (0-9), special characters (!@#$%).
  • 🔹 Example: kL9#pR4@mX2!vQ7$.
  • 🔹 Do not use: dates of birth, names, dictionary words, repeated characters (1111, qwerty).

To generate a password, you can use services like LastPass or 1Password.

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

Possible causes and solutions:

  • 🔌 The router did not save the settings. → Reboot it (unplug it from the socket for 30 seconds).
  • 📡 Incorrect encryption type → Return to WPA2-PSK (some older devices do not support WPA3).
  • 🖥️ The settings on my PC have been lost. → Go to Network and Sharing Center → Change adapter settings, right-click on your connection and select Diagnostics.
How do I disable Wi-Fi on a public router (for example, in a cafe)?

You can't close someone else's router, but you can protect your connection:

  • 🔒 Use VPN (For example, ProtonVPN or NordVPN).
  • 🛡️ Turn on the firewall on your computer (Windows Firewall).
  • 🚫 Do not enter logins and passwords for important services (banks, social networks) on open networks.
Is it possible to hack a closed WPA2 Wi-Fi?

Theoretically yes, but in practice this requires:

  • 🕒 Time: brute-forcing a password can take years (if the password is long and complex).
  • 💻 Equipment: powerful video cards or specialized devices like Wi-Fi Pineapple.
  • 📡 Proximity to the router: Most attacks require physical presence near the network.

If your password complies with the recommendations in this article, the risk of being hacked is minimal.
