1. Preparing devices: what to check before connecting

Before pairing your smartphone and computer, make sure both devices meet the minimum requirements. This will eliminate 80% of potential problems.

Wi-Fi network requirements:

  • 📶 Both devices must be connected to one network (router, access point or hotspot smartphone). Using different networks (for example, a PC via Ethernet and a phone via 4G) will make most methods unavailable.
  • 🔒 If the network is password protected, make sure you have entered the password on both devices. the same keyWhen connecting manually, check the character case!
  • 📡 For stable file transfer, a network speed of at least 5 MbpsAt lower speeds, interruptions are possible when transferring large files (videos, archives).

Device requirements:

  • 📱 On your smartphone: Android 6.0+ or iOS 12+Older OS versions may not support modern protocols (for example, Wi-Fi Direct on Android 5.0 it works with errors).
  • 💻 On your computer: Windows 10/11, macOS 10.14+ or Linux with installed Wi-Fi drivers. On Windows 7, some methods (for example, Fast transfer from Microsoft) does not work.

☑️ Checklist before connecting

Completed: 0 / 5

If you use corporate network (for example, in the office), some methods may be blocked by the administrator. In this case, try connecting via mobile hotspot phone:

  1. On smartphone: Settings → Wireless & networks → Tethering & portable hotspot → Wi-Fi hotspot.
  2. On your PC: Connect to the created network as you would to a regular Wi-Fi network.

2. Method 1: Transfer files via FTP server (without applications)

Protocol FTP (File Transfer Protocol) is one of the most reliable ways to share files over a local network. Its advantage is that you don't need to install additional software on your computer; built-in tools are sufficient. Windows or macOS.

How to set up an FTP server on your smartphone (Android):

  1. Download any FTP application: FX File Explorer, Solid Explorer or FTP Server (from Ridics).
  2. Launch the application and select a folder to share.
  3. Click “Start Server” and an address like this will appear ftp://192.168.1.10:2221.
  4. Enter this address in the address bar Windows Explorer (or Finder on macOS) and click Enter.

For iPhone: There are no full-fledged FTP servers in the App Store due to limitations iOS. Use instead:

  • 📁 Built-in File Sharing feature in the app Files (required) iOS 13+).
  • 🌐 Web interface via applications like FileExplorer (access via HTTP, not FTP).
Method Transfer speed Large file support Need software on PC
FTP (Android) 10–50 Mbps Yes (up to 4 GB) No
HTTP (iPhone) 5–30 Mbps Yes (up to 2 GB) No
Wi-Fi Direct 20–100 Mbps Yes No
Why is FTP faster than Bluetooth?

FTP uses Wi-Fi bandwidth (up to 300 Mbps in the 802.11n standard), while Bluetooth 5.0 is limited to 2 Mbps. The difference is especially noticeable when transferring video or archives.—>

⚠️ Note: If the FTP server on your smartphone turns off, check the power saving settings. Android add the application to exceptions: Settings → Battery → Optimization → Select an app → Unlimited.

3. Method 2: Using specialized applications (AirDroid, Pushbullet)

If you need not only file transfer, but also remote control Use multifunctional apps with your smartphone (SMS, notifications, screen). They work on a "plug and forget" principle—syncing occurs automatically after the initial setup.

Top 3 apps for connecting a PC and a smartphone:

  • 📲 AirDroid — file transfer, screen mirroring, SMS management. The free version is limited. 200 MB/month.

  2. Turn on your smartphone Settings → About phone → Build number (press 7 times to activate developer mode).
  3. Return to Settings → System → Developer Options and turn it on USB debugging.
  4. Connect your phone to your PC via USB and confirm debugging permission.
  5. Launch scrcpy.exe — the smartphone screen will be displayed on the PC. Now you can disconnect the USB and switch to Wi-Fi:
adb tcpip 5555

adb connect 192.168.1.10:5555

After that scrcpy will work via Wi-Fi.

⚠️ Caution: When using TeamViewer or Vysor Over the internet (not a local network), your traffic may pass through the company's servers. Do not transmit sensitive data (passwords, banking applications) through these services.

6. Method 5: Synchronization via cloud services (Google Drive, Dropbox)

If you don't need a direct Wi-Fi connection, but it's important file synchronization between devicesCloud services will be a simple solution. Their advantage is access to files from any device, but their disadvantage is dependence on internet speed and storage limitations.

Comparison of popular services:

Service Free volume Max file size Auto-sync
Google Drive 15 GB 5 TB Yes
Dropbox 2 GB 50 GB (via desktop software) Yes
OneDrive 5 GB 10 GB Yes
Yandex Disk 10 GB 50 GB Yes

How to set up auto-sync (using Google Drive as an example):

  1. Install Google Drive on smartphone and PC.
  2. On smartphone: Settings → Backup → Autostart (select folders to sync).
  3. On PC: Add a folder Google Drive V This computer through the application settings.

To speed up synchronization of large files (for example, videos), first connect your PC to the network via Ethernet, and your smartphone should be charging. This will reduce the risk of disconnection due to low battery or unstable Wi-Fi.

7. Troubleshooting: What to do if devices can't see each other

Even with the correct settings, the connection may not work. Here typical reasons and ways to eliminate them:

Problem 1: Devices are on the same network but do not detect each other.

  • 🔄 Reboot your router (turn off the power for 30 seconds).
  • 📵 Make sure that the PC is not turned on Airplane mode or Battery saving (they can turn off Wi-Fi).
  • 🛡️ Temporarily disable your firewall (Control Panel → Windows Firewall → Turn on or off).

Problem 2: The FTP/HTTP server on the smartphone is not responding.

  • 🔌 Check that the smartphone is allowed Local access in the application settings.
  • 📡 Try connecting by IP address instead of hostname (e.g. 192.168.1.10 instead of myphone.local).
  • 🔄 Restart the server on your smartphone (sometimes the port may be occupied by another process).

Problem 3: Slow file transfer.

  • 📶 Switch your router to the mode 802.11ac (5 GHz) - it's faster than 802.11n (2.4 GHz).
  • 🔌 Connect your PC to the router via Ethernet - This will eliminate Wi-Fi speed limitations.
  • 🗑️ Archive files before transferring (for example, in .zip). Many small files take longer to transfer than one large archive.
⚠️ Warning: If you use public Wi-Fi (in a cafe, airport), the network administrator may block local connections between devices. In this case, the only solution is to create hotspot on your smartphone and connect your PC to it.
