Transferring Data from One Laptop to Another via Wi-Fi: A Complete Guide

Transferring files between laptops via a wireless network is a convenient way to share data without using flash drives or external drives. However, not everyone knows that the speed and security of such transfers depend on the chosen method. In this article, we'll look at 5 proven methods We'll cover the advantages and disadvantages of Wi-Fi data transfer, as well as recommendations for optimizing the process.

The peculiarity of wireless transmission is that it can work both within a local network (if both devices are connected to the same router) and directly - through Wi-Fi Direct or ad-hoc- network. The choice of method depends on the volume of data, security requirements, and the technical capabilities of the laptops. For example, standard Windows sharing is suitable for transferring a couple of documents, but for transferring tens of gigabytes, it's better to use specialized programs like LocalSend or Feem.

1. Preparing laptops for data transfer

Before transferring files, ensure both devices are ready to exchange data. This includes checking network settings, protocol compatibility, and the availability of free space on the receiving laptop.

At first Check your Windows version on both devices. Modern methods (for example, Fast transfer in Windows 11) may not work on older systems like Windows 7. It is also important that both laptops support the same Wi-Fi standards: if one works 802.11ac, and the second one - only by 802.11n, the transfer rate will be limited by the slower protocol.

• 🔧 Update your Wi-Fi adapter drivers on both devices through device Manager or official websites of manufacturers (Intel, Qualcomm Atheros, Realtek).
• 📶 Make sure the signal is stable: If the laptops are far from each other or there are walls between them, use repeater or move the devices closer.
• 🔒 Disable firewalls and antiviruses (Temporarily!) - they may block network connections. Be sure to enable protection after the transfer.
• 📁 Estimate the volume of data: For files larger than 10 GB, it is better to use programs with support multi-streaming (For example, Resilio Sync).

⚠️ Attention: If one of the laptops is connected to a corporate network with restrictions (for example, via VPN (or proxy), Wi-Fi data transfer may be blocked by the administrator. In this case, use ad-hoc- network or physical media.

For maximum speed it is recommended to use 5 GHz channel (if the router supports it). In the router settings (192.168.0.1 or 192.168.1.1) Select channels with minimal interference—for example, 36, 40, 44, or 48. This is especially important in apartment buildings, where neighboring routers' networks may interfere.

2. Method 1: Sharing via local network (SMB)

The most standard method is to use the protocol built into Windows. SMB (Server Message Block)It's suitable for transferring files between laptops connected to the same router. Its main advantage is that it eliminates the need to install additional software.

To set up sharing:

1. On the laptop-source create a folder (for example, For transfer) and right-click on it → Properties → Access → Share.
2. Select a user All and set the resolution Reading and writing (if you need to edit files on the receiving laptop).
3. Go to the tab Security and add a user All with full rights.
4. On the receiving laptop, open Conductor, enter in the address bar \\[Source IP address] (For example, \\192.168.1.100) and copy the files.

⚠️ Attention: If an error appears when connecting 0x80070035 ("Network path not found"), check if the protocol is enabled SMB 1.0 (not recommended due to vulnerabilities) or update Windows to the latest version. Alternatively, use FTP server (section 4).

To speed up the transfer you can archive files V ZIP or RAR before copying. This is especially important for large numbers of small files (such as photos), as it reduces the number of network requests.

3. Method 2: Transfer via Wi-Fi Direct (without a router)

Wi-Fi Direct allows you to connect devices directly, without the need for a router. This is convenient if you are in a place without internet access (for example, on a train or in a cafe). The technology is supported by most modern laptops (starting with Windows 8.1 And macOS 10.10).

To activate Wi-Fi Direct:

1. On the laptop-receiver open Settings → Network & Internet → Wi-Fi → Advanced settings.
2. Enable the option Allow the use of Wi-Fi Direct (on some laptops it may be called Wi-Fi Sense or Wireless projection).
3. On the laptop-source in the same menu select Connect to the device and select the second laptop from the list.
4. Confirm the connection on both devices (you may be asked to enter a PIN).

Once the connection is established, you can transfer files via Conductor (as in method 1) or use specialized programs. Speed Wi-Fi Direct usually higher than when transmitted through a router, since there is no intermediate device. However, the range is limited to 10-15 meters, and if there are obstacles, the connection may be interrupted.

• ⚡ Advantages: high speed (up to 250 Mbps), no dependence on a router, easy to set up.
• ⚠️ Flaws: Not all old laptops support the technology, there may be problems with drivers.
• 🔄 Alternative: If Wi-Fi Direct doesn't work, create ad-hoc-network through Command line (section 5).

4. Method 3: Using an FTP server (for large files)

If you need to transfer tens of gigabytes (for example, backups or video files), the optimal solution would be to deploy FTP servers on one of the laptops. This method is more stable. SMB and supports resumption of interrupted transmission.

To set up an FTP server:

1. Install the program FileZilla Server (free) or use the built-in Windows FTP server (activated via Control Panel → Programs → Turn Windows features on or off → FTP Server).
2. Create a user with access to the desired folder (for example, D:\Transfer).
3. On the receiving laptop, connect to the server via FileZilla Client or Conductor (enter ftp://[IP address] in the address bar).
4. Copy files in passive mode (setting Passive mode in the client it is required for correct operation via the router).

For maximum speed, increase the number of files transferred simultaneously in the FTP server settings (Max threads) to 8-16. It is also recommended to disable encryption (FTPS), if the transmission takes place in a trusted network, this will reduce the load on the processor.

⚠️ Note: If your FTP server is not responding, please check if it is blocked Avast antivirus or Windows DefenderAdd the program to the exceptions or temporarily disable protection.

5. Method 4: Fast transfer programs (LocalSend, Feem, Snapdrop)

If standard methods seem complicated, you can use specialized utilities. They offer a simple interface, high speed, and additional features such as encryption or transfers between different operating systems (Windows, macOS, Android).

Top 3 Wi-Fi Transfer Programs:

• 📲 LocalSend (free, open source): supports file and text transfers, works via a browser or app. Speeds up to 50 MB/s.
• 🚀 Feem (shareware): automatically detects devices on the network, supports Wi-Fi DirectThere is a volume limitation in the free version (1 GB).
• 🌐 Snapdrop (web service): does not require installation, works through a browser using technology WebRTCSuitable for transferring small files (up to 2 GB).

1. Open Command Prompt as administrator.
2. Enter the command to create the network:
netsh wlan set hostednetwork mode=allow ssid="MyAdHoc" key="password123" keyUsage=persistent
3. Start the network:
netsh wlan start hostednetwork
4. On the second laptop, connect to the "MyAdHoc" network with the password "password123".

netsh wlan stop hostednetwork
