How to transfer a file over Wi-Fi: all methods with instructions and comparison

Wireless file transfer is one of the most sought-after features of modern devices. No need to fumble for cables, connect flash drives, or waste mobile data. Simply connect to a single Wi-Fi network, and data can move from your phone to your computer, from your laptop to your TV, or even between adjacent rooms. But how can this be done quickly, securely, and without loss of quality?

In this article we will look at 7 proven methods File transfer over Wi-Fi - from built-in operating system functions to specialized applications. You will learn which method is the fastest for large files (for example, videos in 4K), how to get by without a router if you don't have one at hand, and how to protect your data from interception. We'll also compare the transfer speed between Android, iOS, Windows And macOSso you can choose the best option for your devices.

Spoiler: The most universal method is to use a local network via an IP address, but DLNA is more convenient for TVs, and specialized applications like Send Anywhere are more convenient for smartphones.Read on to understand all the nuances!

1. Transferring files via a local network (by IP address)

This is one of the most reliable methods that works on all devices - from Windows 10/11 to Android 14The main condition is that both devices must be connected to one Wi-Fi network (via a router or access point). The transfer speed is limited only by the capabilities of your router - on modern models with Wi-Fi 6 it can reach 1 Gbps.

How does it work? You create a folder on one device. network, and then connect to it from another device using its IP address. For example, you can share a folder on your laptop and download files to your phone, or vice versa.

• ✅ Pros: No need to install additional programs, works on any device, high speed.
• ❌ Cons: Access rights need to be configured, IP address may change when reconnecting to the network.

Make sure both devices are on the same Wi-Fi network

Remember the IP address of the main device (can be found through the command line)

Share a folder in the sharing settings

Check that your firewall is not blocking the connection-->

Instructions for Windows:

1. Create a folder you want to make a network folder and right-click on it → Properties → Access → Share.
2. In the section Advanced settings check the box Share this folder.
3. Then go to Security → Edit → Add → Enter "All" → OK and give full rights.
4. Find out your computer's IP address: click Win + R, enter cmd, then ipconfig — look for the line IPv4 address.
5. On the second device (for example, a phone), enter the address in the explorer \\[IP address]\folder_name.

For Android You can use a file manager (for example, Solid Explorer or FX File Explorer), which supports connection via SMB (Network Folder Protocol). Enter the computer's IP address, username, and password (if required).

⚠️ Attention: If you have it enabled Windows Defender or a third-party antivirus, it may be blocking access to the network folder. Add an exception for the ports. 137-139 And 445 or temporarily disable protection during the transfer.

2. Using DLNA to stream to a TV or media player

Technology DLNA (Digital Living Network Alliance) allows you to stream files from your phone, computer or laptop directly to Smart TV, Apple TV, Xiaomi Mi Box and other devices. The main advantage is no need to download anything: Videos, music or photos are played directly from your device.

DLNA works on a server-client basis: one device (e.g., a phone) acts as a server, and the TV acts as a client. Speed ​​depends on the router's power, but is usually sufficient for viewing. Full HD- video without delays. For 4K may be required Wi-Fi 5 (802.11ac) or higher.

Instructions for Android:

1. Install the application BubbleUPnP from Google Play.
2. Open the app and select the files you want to transfer.
3. Click Play on and select your TV from the list of devices.
4. Your TV may ask you to confirm the connection (depending on the model).

For Windows:

1. Open Control Panel → Network Settings → Media Streaming.
2. Click Enable media streaming.
3. Select your TV from the list of allowed devices.
4. Now you can open files through Explorer and send them to TV.

⚠️ Attention: Some TVs (especially budget models) TCL or Hisense) may not support formats .mkv or .flac via DLNA. In this case, the files will need to be converted or a different transfer method used.

3. Fast transfer apps (Send Anywhere, Xender, Snapdrop)

If you need to drop files without connecting to a router (for example, on the road or in nature), specialized applications will come to the rescue. They create Wi-Fi Direct connection between devices, which ensures high speed and protection from interception.

The most popular services:

• 📲 Send Anywhere — cross-platform solution with support Android, iOS, Windows and even LinuxYou can transfer files via QR code or 6-digit key.
• 🔄 Xender - optimized for transferring large files (up to 10 GB at a time), supports transfer between Android And iPhone.
• 🌐 Snapdrop — a web service that runs directly in your browser (no app required). Ideal for transferring data between computers.

The transfer speed through such applications is usually higher than through the cloud, because the files are not uploaded to the server, but transferred directly. For example, Send Anywhere uses technology P2P (peer-to-peer), which speeds up the process by 2-3 times compared to Google Drive.

Instructions for Send Anywhere:

1. Install the app on both devices (or open the web version on send-anywhere.com).
2. On the sending device, select the files and press Send.
3. A 6-digit key or QR code will be generated.
4. On the second device, enter the key or scan the QR code – the transfer will begin automatically.

4. Transfer via FTP server (for advanced users)

Protocol FTP (File Transfer Protocol) is the "grandfather" of all network file transfer methods. It's more complex to set up than previous methods, but it gives you complete control over the process. FTP is often used for:

• 📁 Transferring large archives (for example, backups)
• 🔧 Remote file access settings (for example, for working with NAS server)
• 🖥️ Automate data exchange between devices

To set up an FTP server on Windows you can use the built-in IIS or third-party programs like FileZilla ServerOn . Android will do FTP Server from Banana StudioThe speed depends on the network settings, but in a local network it can reach 50-100 MB/s.

Instructions for FileZilla Server:

1. Download and install FileZilla Server from the official website.
2. Run the program and create a new user in the section Edit → Users.
3. Specify the folder to which access will be opened and set the rights (read/write).
4. In the server settings (Edit → Settings) enable passive mode and specify a range of ports (e.g. 50000-51000).
5. On the second device, connect via an FTP client (for example, FileZilla Client or ES File Explorer on Android), entering the server IP address, login and password.

⚠️ Attention: FTP transfers data without encryption, so don't use it for sensitive files on public networks. For security, it's better to set it up SFTP (SSH File Transfer Protocol) or FTPS (FTP over SSL).

How to enable SFTP on Windows?

To set up secure transfer via SFTP on Windows, you will need to install an SSH server, for example, OpenSSH:

1. Open Settings → Applications → Additional components and install OpenSSH server.

2. Start the SSH service via services.msc (find OpenSSH Authentication Agent and run it).

3. Connect to the server via a client (for example, WinSCP) at the address sftp://[your_IP] indicating the login and password for your Windows account.

5. Cloud services (Google Drive, Dropbox, Yandex Disk) - when there is no Wi-Fi, but the Internet is available

If you don't have access to a local network but have internet access, you can use cloud storage. This method is versatile, but has its limitations:

• ⏱️ Speed depends on your internet plan (uploading/downloading large files can use up a lot of traffic).
• 🔒 Security higher than FTP, but files are stored on the company's servers (not suitable for highly confidential data).
• 💰 Restrictions: Free accounts usually provide 5-15 GB of space (e.g. Google Drive — 15 GB, Yandex Disk — 10 GB).

The most popular services:

Instructions for Google Drive:

1. Open Google Drive in a browser or application.
2. Click Create → Upload files and select the required data.
3. Once downloaded, right click on the file and select Share.
4. Add recipient email or generate one Shareable link.
5. On the second device, open the link and download the file.

6. Transfer files via a router (USB drive or network storage)

If your router supports the connection USB drives or has a connector for external hard drive, you can use it as a network storage device. This is convenient if you need to:

• 🔄 Share files between multiple devices simultaneously.
• 📂 Store backups or a media library accessible to all family members.
• 🔌 Avoid overloading your primary devices (files are stored on the router, not on your phone/PC).

Not all routers support this feature. It's typically found in mid-range and high-end models, such as:

• 📡 ASUS RT-AX88U (supports AiDisk)
• 📡 TP-Link Archer C5400 (there is a built-in FTP server)
• 📡 Keenetic Ultra (supports Samba And DLNA)

Instructions for the router ASUS:

1. Connect a flash drive or hard drive to the router's USB port.
2. Go to the router's web interface (192.168.1.1) and go to the section USB Application → AiDisk.
3. Turn on General access and enter your username/password.
4. In the settings, select the protocol (FTP, Samba or WebDAV).
5. On the client device, connect to the router at ftp://192.168.1.1 (or another if the IP has changed).

⚠️ Attention: If a hard drive of the format is connected to the router NTFS, and the router doesn't see it, try formatting the drive in FAT32 or exFAT (but keep in mind that FAT32 does not support files larger than 4 GB).

7. Alternative methods: Bluetooth, NFC, and AirDrop

While these methods aren't directly related to Wi-Fi, they can be useful if a wireless network is unavailable. Let's take a quick look at them:

• 📶 Bluetooth: Suitable for transferring small files (up to 50 MB) for short distances. Speed ​​- up to 2-3 MB/s (V Bluetooth 5.0). For Android You can use the built-in "Send via Bluetooth" function to Windows — Control Panel → Devices → Transfer File.
• 🔗 NFC: It only works at a distance of up to 10 cm and is suitable for transmitting links or small files (such as business cards). Android Enable NFC in settings and touch the devices together.
• 🍎 AirDrop (Apple only): the fastest way between devices Apple (to 10 MB/s). Open the file, click Share → AirDrop and select the recipient.

These methods are inferior to Wi-Fi in speed and versatility, but can help in emergency situations.

How to speed up Bluetooth transfer?

1. Make sure both devices support Bluetooth 4.0 or newer.

2. Turn off other wireless devices (headphones, fitness trackers) that may cause interference.

3. Place the devices as close to each other as possible (ideally on the same surface).

4. On Android turn on the mode Visible to all in Bluetooth settings.

FAQ: Frequently asked questions about transferring files over Wi-Fi

🔹 Why are files transferred slower over Wi-Fi than over a cable?

Wireless network speed depends on several factors:

• Wi-Fi standard: Wi-Fi 4 (802.11n) gives up to 150 Mbps, Wi-Fi 5 — to 867 Mbps, Wi-Fi 6 — to 1.2 Gbps.
• Network load: If several devices are working simultaneously, the speed is divided between them.
• Interference: Other routers, microwaves, or thick walls can reduce the signal.
• Router settings: if enabled Qos (Quality of Service), it may limit the speed for some devices.

To speed up the transfer, try:

• Switch to range 5 GHz (less busy than 2.4 GHz).
• Connect devices closer to the router.
• Disconnect other gadgets from the network during the transfer.

🔹 Is it possible to transfer files over Wi-Fi without a router?

Yes, there are two options:

1. Wi-Fi Direct: Modern smartphones and laptops can create a direct network between each other. For example, on Android go to Settings → Wi-Fi → Wi-Fi Direct and select the device to connect to. Windows can be created access point through Settings → Network & Internet → Mobile Hotspot.
2. Apps like Send Anywhere or Xender: They create a temporary network for file transfer.

Restrictions:

• The speed will be lower than through a router (usually up to 50-100 Mbps).
• The distance between devices should not exceed 5-10 meters.

🔹 How to transfer files from iPhone to Android via Wi-Fi?

Due to restrictions iOS standard methods (eg AirDrop) don't work with AndroidBut there are workarounds:

1. Send Anywhere: Install the application on both devices and follow the instructions (generate a key or QR code).
2. Google Drive/Yandex Disk: download files from iPhone to the cloud, then download them to Android.
3. FTP server on Android: install on Android application FTP Server, and on iPhone — FileExplorer, then connect via IP.

For transferring photos and videos it is most convenient to use Google Photos:

• On iPhone Upload a photo to Google Photos.
• On Android Sign in to the same Google account and download the files.

🔹 Is it safe to transfer files over an open Wi-Fi network (for example, in a cafe)?

Transfer files via open Wi-Fi network (without a password) is associated with risks:

• 🕵️ Data interception: if you use FTP or SMB Without encryption, an attacker can intercept files.
• 🔄 MITM attacks: In open networks, man-in-the-middle attacks are possible, where a hacker replaces data.

How to protect yourself:

• Use encrypted protocols: SFTP, HTTPS (in cloud services), WebDAV with SSL.
• Set up VPN on both devices before transferring.
