Wi-Fi Sharing Between Laptops on the Same Network: A Complete Guide

Sharing files between laptops within the same Wi-Fi networks — a task faced by students during group work, office workers, and ordinary users who want to quickly transfer photos or documents without using flash drives. Despite its apparent simplicity, setting up shared access often presents difficulties: network environment If it doesn't display the devices, then the access rights are configured incorrectly, or the firewall is blocking the connection.

In this article we will look at all current methods public access organization - from standard tools Windows (including Windows 11) to cross-platform solutions for macOS And LinuxWe'll pay special attention to common errors that prevent laptops from "seeing" each other and how to fix them. If you've ever encountered the message "Network path not found" or "No access to resource", here you will find the solution.

⚠️ Important: All instructions assume that both laptops are connected to one Wi-Fi network (via a router or access point). If the networks are different, additional routing configuration or the use of a VPN will be required.

1. Preparing the network: checking the connection and router settings

Before setting up sharing on the laptops themselves, make sure the network is configured correctly. Often, the problem lies not with the operating system, but with the settings. router or network equipment.

The first thing you need to do is check whether the laptops can see each other on the network. To do this:

1. On Windows open Command line (Win + R → enter cmd) and run the command:

   ping [IP address of the second laptop]

   For example: ping 192.168.1.102.

2. If the answers are like "Timeout exceeded" — this means the laptops can't "see" each other. There could be various reasons: the computer is turned off DHCP on the router, client isolation mode is activated (AP Isolation) or blocking MAC addresses.

To rule out problems at the router level:

• 🔧 Check that the router is turned on DHCP server (usually in the section LAN or DHCP). If it is disabled, laptops will not receive automatic IP addresses.
• 🚫 Turn off the feature AP Isolation (client isolation) - it blocks the interaction of devices on the same network.
• 🔄 Restart your router if the changes don't apply (sometimes a factory reset helps).

If ping is going well (answers like "Reply from 192.168.1.102..."), but sharing still doesn't work—the problem lies with the operating system settings. Let's move on to the next section.

2. Setting up sharing in Windows (Network Neighborhood)

The standard way to share files in Windows - using the function Network Environment (or Net V Windows 11). However, it's disabled by default for security reasons. Let's walk through the step-by-step setup.

Step 1: Enable network discovery

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Select on the left Change advanced sharing options.
3. Enable options:
   • 🔹 Network discovery (for all profiles: private, guest, all networks).
   • 🔹 File and Printer Sharing.
   • 🔹 Allow Windows to manage HomeGroup connections (if any).

Step 2: Sharing the folder

1. Right-click on the folder you want to share and select Properties → Access.
2. Click Share... and select a user All (Everyone).
3. Set permission level: Reading (view only) or Reading and writing (editing).
4. Go to the tab Security and add a user All with the same rights.

Network discovery is enabled|File sharing is enabled|Folder is shared with user "Everyone"|Access permissions are configured in the "Security" tab|Firewall is not blocking file sharing-->

After this, the folder should become visible in Network → [Name of the second laptop]If it's not there, check it. firewall (allow incoming connections for File and Printer) And antivirus (sometimes it blocks network traffic).

3. Alternative methods: FTP server and cloud services

If standard sharing doesn't work or you need remote access (for example, from another network), you can use FTP server or cloud servicesLet's look at both options.

Method 1. Local FTP server (FileZilla, built-in Windows tools)

• 💾 For Windows the easiest to use FileZilla Server (free). After installation:
1. Create a user and specify the folder to access.
2. In the server settings, enable passive mode (Passive mode) and specify the port range (for example, 50000-51000).
3. On the second laptop, connect via FileZilla Client or Conductor (enter ftp://[IP address of the first laptop]).
5. 🖥️ In macOS/Linux You can launch an FTP server using built-in tools:

   sudo apt install vsftpd # For Linux (Debian/Ubuntu)
   sudo systemctl start vsftpd

   Configuration file: /etc/vsftpd.conf (uncomment local_enable=YES And write_enable=YES).

Method 2. Cloud services (Google Drive, Dropbox, Yandex Disk)

If your internet speed allows, the easiest way is to upload files to the cloud and share a link. Benefits:

• ✅ Works even if the laptops are on different networks.
• ✅ No need to configure network settings.
• ✅ Change history and backup.

Disadvantages: speed limits (depending on the plan) and volume (free accounts usually provide 5–15 GB).

How to speed up cloud uploads?

Use wired Ethernet instead of Wi-Fi if your router supports Gigabit ports.

Disable background applications (torrents, updates) that consume traffic.

Compress folders before downloading (ZIP/RAR) to reduce the data volume.

4. Sharing between Windows and macOS/Linux

Cross-platform file sharing requires additional settings, as the protocols SMB (used in Windows) and AFP/NFS (macOS/Linux) are different. Let's consider two scenarios.

Scenario 1: Accessing a Windows folder from macOS/Linux

• 🪟 On Windows set up sharing as in Section 2, but in Properties → Access select protocol SMB (default).
• 🍎 On macOS:
  1. Open Finder → Go → Connect to Server (Cmd + K).
  2. Enter smb://[Windows PC IP address].
  3. Log in with your account Windows (if it asks for a password).
6. 🐧 On Linux (Ubuntu/Debian):

   sudo apt install cifs-utils
   mkdir ~/windows_share
   sudo mount -t cifs //[IP address]/[folder_name] ~/windows_share -o user=[user_name]

Scenario 2: Accessing a folder on macOS/Linux from Windows

• 🍎 On macOS:
  1. Open System Preferences → Sharing.
  2. Activate File sharing and add the folder.
  3. IN Parameters enable protocol SMB.
7. 🐧 On Linux install Samba:

   sudo apt install samba
   sudo nano /etc/samba/smb.conf

   Add to the end of the file:

   [shared]
   path = /path/to/folder
   writable = yes
   guest ok = no

   Restart the service: sudo systemctl restart smbd.

8. 🪟 On Windows open \\[macOS/Linux IP address] V Conductor.

⚠️ Attention: When connecting between Windows 11 And Linux/macOS may need to be disabled SMB encryption on Windows (in Control Panel → Programs → Turn Windows features on or off → uncheck Support for SMB 1.0 encryption).

5. Solving typical problems

Even with proper settings, sharing may not work. Here are the most common errors and how to fix them:

Problem	Possible cause	Solution
"Network path not found"	Incorrect IP address or computer name	Check IP via ipconfig (Windows) or ifconfig (macOS/Linux). Use IP instead of PC name.
"No access to resource"	Insufficient rights or blocked by antivirus	Check permissions in Properties → SecurityDisable your antivirus temporarily.
Laptops can't see each other on the network.	Different workgroups or NetBIOS disabled	Set the same workgroup (eg. WORKGROUP) and enable NetBIOS in the network adapter properties.
Slow file transfer speed	Wi-Fi interference or router limitations	Switch to range 5 GHz or use an Ethernet cable.

If the problem persists, check:

• 🔌 Network profile type: V Network and Control Center must be specified Private network, and not Public.
• 🛡️ Firewall: Disable it temporarily to check if it is blocking traffic.
• 🔄 SMB protocol version: Windows 11 uses by default SMB 3.1.1, which may not be supported by older devices.

6. Security: How to protect shared access from outsiders

By sharing folders, you risk exposing them not only to trusted devices but also to potential attackers (if they connect to your Wi-Fi network). The following measures will help minimize these risks:

Methods of protection:

• 🔐 Use accounts: Do not open access for the user All (Everyone). Create a separate user with a password and grant access only to him.
• 🌐 Disable guest access: In the settings Samba (Linux) or Network access (Windows) Disable anonymous connections.
• 🔗 Restrict access by IP: In the router settings (MAC/IP filtering) allow connection only for MAC addresses your laptops.
• 🔄 Change your Wi-Fi password regularly: Especially if guests or neighbors connect to the network.

Critical! If you have devices on your Wi-Fi network IoT (smart bulbs, cameras), they can become vulnerable to hacking. Place them in guest network router, separately from the main devices.

For maximum security, consider using VPN (For example, WireGuard or OpenVPN) to encrypt traffic between laptops, even on a local network.

7. File sharing without public access: alternative programs

If setting up a network environment seems complicated, you can use specialized file transfer programs. They are often easier to use and don't require in-depth knowledge of network protocols.

Top 5 Wi-Fi File Sharing Apps:

• 📁 LocalSend (cross-platform, open source) - transfer files between devices on the same network without the cloud.
• 🚀 Snapdrop (web service) - works through a browser, does not require installation.
• 🔗 Feem - supports file transfer between Windows, macOS, Android And iOS.
• 📎 Dukto R6 - simple interface, drag-and-drop support.
• 🌐 Resilio Sync — synchronization of folders between devices using the torrent principle.

The advantages of such programs:

• ✅ No need to configure access rights or protocols.
• ✅ Frequently supported QR codes for quick connection.
• ✅ Works even if laptops are on different subnets (via cloud relays).

Disadvantage: Some programs (eg. Feem) have speed limitations in the free version.

8. Optimizing file transfer speed over Wi-Fi

If files are copying too slowly, the problem may be in the settings. router, Wi-Fi adapter or transmission protocolHere's how to speed up the process:

Router settings:

• 📶 Switch to range 5 GHz (less congested, higher speed).
• 🔄 Turn on WMM (Wi-Fi Multimedia) to prioritize traffic.
• 📊 Set a fixed channel (eg. 36 or 40) instead of Autoto avoid interference.

Laptop settings:

• 🖥️ Update your driver Wi-Fi adapter (especially relevant for Windows).
• 🔌 Use the standard 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6), if the router supports it.
• 📂 To transfer large files, zip them in ZIP/RAR - this will reduce the volume of data.

Transmission protocols:

• 🔄 For Windows turn on SMB Direct (requires a network card with support RDMA).
• 🐧 On Linux use rsync to synchronize folders:

  rsync -avz --progress /path/to/source/folder user@[IP address]:/path/to/destination/folder

If after all optimizations the speed remains low, check the network load with other devices (for example, IP cameras or torrents).

FAQ: Frequently Asked Questions about Wi-Fi Sharing

Is it possible to set up shared access without a router, directly between laptops?

Yes, for this create ad-hoc network (V Windows) or use the mode Wi-Fi Direct (If the adapters support it). However, in this case, the speed will be lower, and setup will be more complicated than using a router.

Why is the speed when copying files high at first and then drops?
This is normal behavior for Wi-Fi networks, especially in the range 2.4 GHzThe reason is automatic speed reduction when the signal deteriorates or the router overheats. Try:
• Switch to 5 GHz.
• Reduce the distance between laptops and the router.
• Disable power saving for Wi-Fi adapter V Device Manager.
