In the age of ubiquitous internet connectivity, protecting personal data is becoming critical for every user. Many home router and laptop owners are unaware that their device, whether in public places or even at home, could be exposed to prying eyes due to improper network profile settings. Private network — this is not just a marketing term, but a specific operating system mode that hides your device from other gadgets on the same access point.
When you connect to a new Wi-Fi network, the system often asks if you want to make your computer discoverable, and by default, it often selects the "Public" network for maximum security. However, if you're at home, you'll need to make your Wi-Fi network private to be able to use a printer, transfer files, or control your smart home without being constantly blocked by a firewall. In this article, we'll cover all the nuances of profile switching and security settings.
Understanding the differences between a public and private profile
Operating systems such as Windows 10 and 11 use the concept of network profiles to manage firewall rules. Public profile This assumes you're in a café, airport, or hotel where hackers could be connected to the same network. In this mode, the system minimizes incoming connections, making your computer "invisible" to other devices.
Unlike him, private profile Trusts the environment. It opens ports for service protocols, allows discovery of other computers on the local network, and provides access to shared folders. Windows Automatically applies stricter traffic filtering rules when the public type is selected, which may block legitimate applications.
It's important to understand that switching your network type doesn't encrypt your traffic, but it does change the rules of how your device interacts with its surroundings. If you're in a trusted environment, such as your home, using a public profile will only create inconvenience without providing any real security benefit.
⚠️ Warning: Never switch the network type to "Private" when connecting to free Wi-Fi in shopping centers or public transport, as this may open ports for attacks from the provider's local network.
Setting up network type in Windows 10 and 11 via Settings
The easiest and safest way to change your profile is to use the operating system's default settings menu. This method doesn't require administrator privileges (like the command prompt) and minimizes the risk of error. First, open the Start menu and go to "Settings," which is indicated by the gear icon.
In the window that opens, select the "Network & Internet" category. Here you will see a list of available connections. If you are using a wireless connection, find "Wi-Fi" in the left menu (in Windows 10) or in the center of the screen (in Windows 11). Click the name of your active network or the "Properties" button below it.
The network properties screen displays the current profile. You'll see a toggle or radio buttons to choose between "Public" and "Private." Select the desired option, and the system will immediately apply the new firewall rules. On some corporate networks, this option may be blocked by group policies.
☑️ Check network status
Using PowerShell to Change Network Profile
For advanced users or system administrators who need to change settings on multiple computers or when the graphical interface is unresponsive, the PowerShell command line is ideal. This method provides deeper control over network adapters and allows you to see the exact profile name, which is sometimes different from the SSID.
To get started, you need to run PowerShell as an administrator. Right-click the Start button and select the appropriate option from the menu. Enter the command Get-NetConnectionProfileto see a list of all network interfaces and their current categories (Public or Private).
To change the profile, use the command Set-NetConnectionProfile. You will need to know the interface name or its index. For example, the command Set-NetConnectionProfile -Name "Network_Name" -NetworkCategory Private Forces the network to switch to private mode. This is especially useful if the system "forgot" the settings after updating drivers.

If PowerShell returns an access error, make sure you're running the console as an administrator. Also, check if your antivirus software is blocking changes to system network settings.
Router Configuration: Client Isolation and Guest Zones
The security of your private network depends not only on Windows settings, but also on the configuration of the router itself. The key function here is AP Isolation (Access Point Isolation) or Client Isolation. When enabled, devices connected to Wi-Fi cannot see each other, even if the computers are set to the "Private Network" profile.
For home use, client isolation is typically disabled on the main network but enabled on the guest network. The guest network creates a virtual segment completely separate from your personal local network with NAS storage and printers. This is the best way to provide guests with internet access while keeping their data secure.
Log into your router's web interface, usually accessible at 192.168.0.1 or 192.168.1.1Find the "Wireless" section and look for the "Guest Network" settings. Enable it and set a separate password. Make sure "Local Area Network Access" is disabled for the guest profile.
| Parameter | Main network | Guest network | Public Wi-Fi |
|---|---|---|---|
| Access to files | Allowed | Prohibited | Prohibited |
| Device visibility | All are visible | Hidden | Hidden |
| Windows profile type | Private | Public | Public |
| Encryption | WPA2/WPA3 | WPA2/WPA3 | Open/Captive |
Problems discovering devices on the local network
A common problem after updating the operating system is the disappearance of network printers or the inability to broadcast video to a TV via DLNA or CastThis happens because Windows resets the network profile to "Public", blocking discovery protocols.
If devices are still not visible after changing the profile, check discovery services. Open Control Panel → Network and Sharing Center → Change advanced sharing settings. Make sure network discovery and file sharing are enabled for the current profile.
It's also worth paying attention to Windows services. Click Win + R, enter services.msc and find the "Function Discovery Resource Publication" service. Set its startup type to "Automatic" and start the service. Without this component, the computer will not be able to properly advertise itself on the network.
⚠️ Note: Router interfaces and Windows menus may vary depending on the firmware version and OS build. If you can't find a specific option, consult the official documentation from your equipment manufacturer.
Additional measures to protect your home network
Simply making your Wi-Fi a private network isn't enough to ensure complete security. Using modern encryption standards is crucial. Make sure the protocol selected on your router is WPA3 or at least WPA2-AES. The outdated WEP and WPA-TKIP standards are easily cracked in minutes.
Update your router firmware regularly. Manufacturers often release patches that fix vulnerabilities that allow hackers to access network settings. It's also recommended to change the default router administrator password, which is often "admin/admin."
For maximum privacy, consider using encrypted DNS (DoH) or setting up a VPN directly on your router. This will hide your browsing history from your ISP and protect the traffic of all connected devices, including smart light bulbs and refrigerators, which don't have security features on their own.
Is it possible to make a network private if the router is not mine (for example, in a dorm)?
You can change the network profile only on your computer (making it private), but this won't change the router's settings. Dormitories often have client isolation enabled at the hardware level, so changing the profile on your PC won't allow you to access your neighbors' files, but it could open your PC to attacks if the network administrator hasn't configured isolation correctly.
Does network type affect internet speed?
No, choosing between "Private" and "Public" networks only affects firewall rules and device visibility. Data transfer speed depends on signal quality, channel congestion, and your provider's plan, but not on the network profile type.
How to reset network settings to default?
In Windows 10 and 11, you can perform a network reset. Go to Settings → Network & Internet → Advanced network settings → Network reset. This will delete all saved Wi-Fi passwords and reset all profiles to factory defaults (usually "Public" for new connections).
