How to Change Your Laptop's Wi-Fi Name: 3 Methods for Windows, macOS, and Linux

Have you noticed that your laptop appears on your Wi-Fi network under a strange or confusing name? It might be a standard name like DESKTOP-123ABC or User-PC, which was automatically assigned by the system. On a local network, such a name can cause confusion, especially if several devices are connected. Changing the computer's hostname not only simplifies network identification but also helps when setting up file sharing, printer access, or remote control.

In this article you will find step-by-step instructions for all popular operating systems: Windows 10/11, macOS And Linux (including Ubuntu And Debian). We'll also discuss why a laptop's name may not change on the network immediately after a reboot, how to check the current name via the command line, and what to do if new settings aren't applied. We'll also cover typical mistakes and ways to resolve them - for example, when the name is reset after a system update or conflicts with another device on the network.

If you've never changed your computer name before, don't worry: the process takes no more than 5 minutes and doesn't require any special skills. Just follow the instructions and take into account the nuances of your operating system. And for those who prefer automation, we'll provide commands for quickly changing the name using Terminal or PowerShell.

1. Why change the laptop's Wi-Fi network name?

Computer name (or hostname) is an identifier used on a local network to address a device. By default, operating systems assign random or generic names, which can be inconvenient for everyday use. Here are some reasons why you might want to change the name:

• 🔍 Easy identification: Instead of LAPTOP-5678FGH You can use a meaningful name, for example Ivan-Laptop or Office-MacBook.
• 📂 File sharingWhen setting up network folders or printers, it is more convenient to select a device by a user-friendly name rather than by IP address.
• 🔒 Security: Standard names can reveal information about the device model or OS version, making it easier for attackers.
• 🖥️ Remote control: Programs like TeamViewer or AnyDesk often display the name of the computer to connect to.
• 📡 Online conflicts: If there are two devices with the same name on the same network, connection errors may occur.

Additionally, some applications (such as local multiplayer games or streaming programs) use the computer name to create sessions. If it contains Cyrillic or special characters, this can lead to crashes. Therefore, it's best to use Latin characters and avoid spaces.

2. How to change the laptop name in Windows 10 and 11

IN Windows The process of changing the computer name is almost the same for both versions 10 And 11The main difference is the interface design. We'll look at both options, as well as an alternative method via PowerShell for experienced users.

Method 1: Through Windows Settings (GUI)

This is the simplest method, suitable for beginners. Follow the instructions:

1. Open the menu Start and select Parameters (gear icon) or click Win + I.
2. Go to the section System → About the system.
3. In the block Device specifications find the button Rename this PC and press it.
4. Enter a new name (Latin characters, numbers, and hyphens only). Length: up to 15 characters.
5. Click Next, then Restart now.

After rebooting, the changes will take effect. To check the new name, open a command prompt (Win + R → cmd) and enter:

hostname

Close all important programs

Save open documents

Make sure you have administrator rights

Remember the current name in case of a rollback-->

Method 2: Via PowerShell (for advanced users)

If you prefer the command line, use PowerShell:

1. Launch PowerShell as administrator (find in search, right-click → Run as administrator).
2. Enter the command to check the current name:

   Get-ComputerInfo | Select CsName

3. To change the name, run:

   Rename-Computer -NewName"NEW_NAME" -Restart

   (replace NEW_NAME to the desired, without quotation marks).

The command will automatically reboot the computer. This method is useful for administering multiple computers on a network or creating scripts.

Common Windows Errors and Their Solutions

Sometimes, after changing a computer's name on the network, the old one appears. Here are possible causes and solutions:

⚠️ Attention: In corporate networks with a domain Active Directory Changing the computer name may be blocked by security policies. Please check with your IT department before proceeding.

3. Change the laptop name in macOS (Monterey, Ventura, Sonoma)

On MacBook or iMac the process is a little different from Windows, but no less simple. In macOS There are three types of names that can be displayed on the network:

• 🖥️ Computer name (Computer Name) - used in the local network.
• 📡 Local host name (Local Hostname) — for Bonjour services (e.g. AirDrop).
• 🌐 Internet name (Network Name) - for remote access.

We'll focus on the first item, as it's the one that appears in the list of Wi-Fi devices. This guide is relevant for macOS Monterey, Ventura And Sonoma.

Step-by-step instructions

1. Open System Preferences (gear icon in the Dock or via the Apple menu).
2. Go to the section General access.
3. At the top of the window you will see a field Computer name. Click the button Change....
4. Enter a new name (you can use Cyrillic, but for compatibility, Latin is better).
5. Close the window and confirm the changes. A reboot is not required, but you may need to log out.

To check the changes, open Terminal and enter:

scutil --get ComputerName
scutil --get LocalHostName

If you use AirDrop or Screen Sharing, please update as well Local host name in the same settings window. It should be in the format name.local (For example, my-macbook.local).

What if the name doesn't change in Finder?

If the name in the Finder sidebar (under "Network") has not updated after changing it, try:

1. Turn Wi-Fi off and on again.

2. In the Terminal, run sudo killall mDNSResponder.

3. Restart your MacBook.

This will reset the Bonjour cache, which is responsible for displaying devices on the local network.

macOS Features When Changing a Name

Unlike Windows, macOS allows you to use Cyrillic characters in the computer name, but this may cause problems when connecting to it from devices on Windows or LinuxFor example, when trying to access a network folder by name \\MyMacbook You may get an error. In such cases:

• Use Latin for Local host name.
• For network access, use the IP address instead of the name (you can find it in System Preferences → Network).

⚠️ Attention: If your MacBook connected to a corporate network with a server Open DirectoryChanging your name may disrupt access to resources. Consult your administrator before proceeding.

4. How to change the laptop name in Linux (Ubuntu, Debian, Fedora)

IN Linux-In different distributions, the process depends on the network manager used and the OS version. We will look at a universal method through hostnamectl (relevant for Ubuntu 20.04+, Debian 11+, Fedora), as well as manual editing of configuration files for older systems.

Method 1: Via hostnamectl (recommended)

This is the most reliable method for modern distributions:

1. Open Terminal (Ctrl + Alt + T).
2. Check your current name:

   hostnamectl status

3. Change the name (replace new-name to the desired):

   sudo hostnamectl set-hostname new-name

4. Update hosts-file:

   sudo nano /etc/hosts

   Find the line with 127.0.1.1 and replace the old name with the new one. Save the changes (Ctrl + O → Enter → Ctrl + X).

5. Reboot the system:

   sudo reboot

After rebooting, check the changes:

hostname
cat /etc/hostname

Method 2: Manual editing (for older versions)

If hostnamectl unavailable (for example, in Ubuntu 18.04), change the name manually:

1. Open the file /etc/hostname:

   sudo nano /etc/hostname

2. Delete the old name and enter a new one (one line without spaces).
3. Update /etc/hosts, as described above.
4. Apply changes without rebooting:

   sudo service hostname restart
   sudo service networking restart

Linux Problems and Their Solutions

IN Linux After changing the name, the following issues may arise:

If you use NetworkManager, after changing the name, restart it:

sudo systemctl restart NetworkManager

5. How to check if the name has changed on a Wi-Fi network

After changing your hostname, it's important to ensure the changes have been applied correctly and are visible on the local network. Here are a few ways to check:

Method 1: Via the command line

In any OS, you can use commands to check the current name:

• 🪟 Windows:

  hostname
  ipconfig /all | find"Host Name"

• 🍎 macOS:

  scutil --get ComputerName
  scutil --get LocalHostName

• 🐧 Linux:

  hostname
  cat /etc/hostname

Method 2: Via a router

Most modern routers display a list of connected devices with their names. To check:

1. Open the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Log in (default logins/passwords are indicated on the router sticker).
3. Find the section Connected devices, DHCP or Local area network.
4. Check if the new name appears next to your laptop's IP address.

If the name has not updated, clear the DHCP cache on the router or reboot it. On some models (e.g., TP-Link or ASUS) there is a button Refresh the list.

Method 3: Via another device on the network

You can check the visibility of your laptop from another computer, phone, or tablet:

• 📱 From Android/iOS: Use apps like Fing or Network Analyzer to scan the network.
• 💻 From another PC:
  • IN Windows open Net in Explorer or run ping COMPUTER_NAME in CMD.
  • IN macOS/Linux use ping NAME.local or nmap -sn 192.168.1.0/24.

⚠️ Attention: If you're using a VPN or proxy, your computer name may not be visible on your local network. Disable them before testing.

6. Common mistakes and how to avoid them

Users often encounter common issues when changing their laptop's Wi-Fi network name. Let's look at the most common ones and how to solve them.

Error 1: Name does not change after reboot

If after all the manipulations the old name continues to be displayed, the reasons may be as follows:

• 🔄 DNS cache: Clean it in Windows (ipconfig /flushdns) or restart the service mDNSResponder on macOS.
• 📡 Router cache: Reboot your router or find the option in its settings Clear DHCP Clients.
• 🔧 Name conflict: Make sure the new name is unique on your network (use this to check) nbtstat -a COMPUTER_NAME in Windows).
• 🛡️ Domain Policies: In corporate networks, the name may be managed by the server. Check via gpresult /r.

Error 2: You cannot enter Cyrillic characters or spaces.

Many users try to use Russian letters or spaces in their computer names, but encounter errors. Hostname formation rules:

• ✅ Allowed: Latin (az, AZ), numbers (0-9), hyphen (-).
• ❌ Prohibited: spaces, Cyrillic, special characters (!@#$%), underline (_).
• 📏 Length: up to 15 characters (on Windows), up to 63 on Linux/macOS (but it is recommended not to exceed 15 for compatibility).

Exception: macOS allows you to use Cyrillic characters in the "Computer Name," but this may cause issues when accessing from Windows/Linux. For cross-platform compatibility, stick to Latin characters.

Error 3: Name resets after system update

Sometimes after major updates (for example, switching from Windows 10 on 11 or updates macOS) the computer name is reset to the default. This happens because:

• 🔄 Reset network settings: The system may perceive the update as a new installation.
• 📜 Profile conflict: In domain networks, the name can be controlled by group policies.
• 🛠️ Migration errors: When updating, not all configuration files are transferred correctly.

To avoid this:

• Before the update lock the current settings (take a screenshot or write down the name).
• After the update check the name and change it again if necessary.
• IN Windows use PowerShell to force the name to be applied:

  Rename-Computer -NewName"NAME" -Force

Error 4: Conflict with another device on the network

If two devices on the same network have the same name, this can result in:

• 🚫 Denial of connection to network resources.
• 🔄 Unpredictable behavior when accessed by name (for example, you are connecting to the wrong PC).
• ⚠️ Errors in router or DHCP server logs.

To check for conflicts:

• IN Windows execute:

  nbtstat -n

  and compare Computer name with other devices.

• IN Linux/macOS scan the network:

  nmap -sn 192.168.1.0/24

If a conflict is detected, change the name to something unique or temporarily disconnect the second device from the network.

7. Additional network setup tips

Changing your computer name is just the first step to comfortable work on your local network. Here are a few recommendations to help optimize interaction between devices:

Tip 1: Set up a static IP address

If you frequently access your laptop by name (for example, to access shared folders), assign it a static IP on the network. This will prevent problems when changing the address via DHCP.

How to set up:

• 🪟 Windows:
  1. Open Settings → Network & Internet → Wi-Fi → Configure adapter settings.
  2. Right-click on your connection → Properties → Internet Protocol version 4 (TCP/IPv4).
  3. Select Use the following IP address and enter the data (for example, 192.168.1.100).

🍎 macOS:

1. Open System Preferences → Network → Wi-Fi → Advanced.
2. Tab TCP/IP → Configure IPv4 → Manually.

🛡️ Important: Make sure that the selected IP is not in the DHCP pool of your router (usually this is a range with 192.168.1.100 to 192.168.1.200).

Tip 2: Turn on network discovery

To make your laptop visible to other devices on the network (for example, for file sharing), enable network discovery:

• 🪟 Windows:
  1. Open Control Panel → Network and Internet → Network and Sharing Center.
  2. Select Change advanced sharing options.
  3. Turn on Network discovery And File and Printer Sharing.

🍎 macOS:

1. Open System Preferences → Sharing.
2. Turn on File sharing And Screen sharing (if necessary).
3. 🐧 Linux: Use Samba for folders:

   sudo apt install samba
   sudo smbpasswd -a user

Tip 3: Use mDNS for local access

Technology Multicast DNS (mDNS) allows you to address devices by name name.local without setting up a DNS server. It is enabled by default in macOS And Linux, but in Windows requires installation Bonjour Services (included in the package) iTunes) or enabling the function LLMNR.

To check if mDNS is working:

• From another device, run:

  ping COMPUTER_NAME.local

• If there are no answers, install Avahi (Linux) or Bonjour (Windows).

Tip 4: Security when changing your name

The hostname may reveal information about your device. To minimize the risks:

• 🔒 Do not use personal information in your name (e.g. Ivan-Laptop or Home PC).
• 🛡️ Avoid specifying the model or OS (e.g. Lenovo-Windows11).
• 🔄 Regularly check the list of devices in your router for unknown hosts.

8. FAQ: Frequently asked questions about changing the laptop name

❓ Do I need to restart my laptop after changing the name?
Yes, in most cases a reboot is required for changes to take effect at the system and network level. However:
• IN macOS Sometimes it is enough to log out of your account and log back in.
• IN Linux You can apply changes without rebooting by restarting the service hostname.
• IN Windows A reboot is always required.

If you do not reboot the device, the new name may not be displayed on the network even if the command hostname shows the current value.

❓ Is it possible to use Cyrillic characters in a computer name?

Technically yes, but it can cause problems:

• 🪟 Windows does not support Cyrillic in the hostname (only Latin, numbers, hyphens).
• 🍎 macOS allows Cyrillic in the "Computer Name", but this may
