The modern pace of life demands instant data exchange, and using USB flash drives or external hard drives for this purpose seems archaic. When it becomes necessary to quickly transfer gigabytes of photos, videos, or work archives between two computers in the same apartment or office, a wireless network becomes the most logical solution. WiFi It allows you to transfer data at speeds that in many cases exceed the capabilities of older USB ports, while eliminating the clutter of wires.
There are several proven methods for implementing this task, from built-in operating system tools to specialized software. The choice of a specific method depends on the Windows version, the volume of information being transferred, and your level of technical expertise. In this article, we'll cover how to set it up in detail. local network, use cloud storage and third-party utilities for the fastest possible data synchronization.
The main advantage of wireless transfer is mobility. You don't need to physically move media, running from one device to another. Both computers need to be connected to the same access point, whether it's a home router or sharing from a phone. However, it's important to keep in mind that connection stability directly impacts transfer speed, so it's better to use a wireless standard for working with large files. 802.11ac or newer.
Preparing equipment and setting up the network
Before configuring the software, you need to ensure the physical infrastructure is ready for operation. Both computers must be within range of a strong signal. If you're using a laptop, make sure the WiFi adapter is activated and the corresponding module is installed on your desktop computer. For stable operation, it's recommended that both devices be connected to the same router frequency.
Modern routers often operate in two bands: 2.4 GHz and 5 GHz. For large data transfers, it's critical that both computers are connected to the same band. 5 GHzIt provides higher throughput and less interference, which will significantly speed up file copying. If one device is connected to 2.4 GHz, the overall connection speed will drop to the level of the slowest network member.
⚠️ Note: If you're using a guest WiFi network or corporate internet connection with AP Isolation enabled, computers won't be able to see each other. To transfer files, you must connect to the main network, where communication between devices is allowed.
It's also worth checking the network profile status. In Windows, by default, when you connect to a new network, it's identified as "Public," hiding your computer from others. You need to change this status to "Private" to allow discovery. This can be done through the network settings in the system tray or through the Control Panel.
Creating a shared folder and setting up access
The most classic and reliable method, which doesn't require installing additional software, is creating a Shared Folder using Windows. This method is ideal for regularly exchanging files between a desktop PC and a laptop. To begin, select the directory you plan to share or create a new folder with a descriptive name, such as Exchange.
Right-click the folder and select "Properties." Go to the "Sharing" tab and click "Advanced." Here, check "Share this folder." Then click "Permissions" to configure permissions. For a home network, it's best to grant full permissions to the "Everyone" group. While this isn't entirely secure, it's acceptable in a trusted environment.
- 📂 Make sure network discovery is enabled in your network settings.
- 🔒 Make sure password protection is enabled if you want to control access.
- 📡 Make sure your firewall is not blocking incoming SMB connections.
An important point is to configure the sharing settings. Go to Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsIn the "Private" (current) profile, enable network discovery and file and printer sharing. It's also recommended to enable sharing so Windows devices can manage connections.
☑️ Checking shared folder settings
Transferring files over a local network (SMB protocol)
Once the folder is shared, you can begin transferring data. On the second computer, open File Explorer and enter the IP address of the first computer in the address bar. You can find it by opening the command prompt on the first PC and entering the command ipconfigYou'll be interested in the "IPv4 address" line, which typically looks like 192.168.1.X or 192.168.0.X.
Enter the path in the address bar of the second computer's Explorer in the format \\192.168.1.X (where X is the address of the first PC). If the system prompts you for credentials, enter the username and password for the first computer's account. After successful authorization, you will see the shared folder and will be able to copy files as if they were on your local drive.
⚠️ Note: When copying large numbers of small files, the speed may be significantly lower than the stated WiFi throughput. The SMB protocol incurs overhead in verifying each file. For thousands of photos, it's best to first compress them into a single archive.
For ease of use, you can map a network folder as a network drive. In File Explorer, click "This PC," then select "Map network drive" from the menu. Assign a letter (for example, Z:) and specify the path to the folder. This folder will now appear in "My Computer" as a separate drive, making it easier to work with documents.
What to do if Windows doesn't see your computer on the network?
If automatic discovery doesn't work, try entering the IP address manually. Also, make sure the "Function Discovery Resource Publishing" service is running in services.msc. Sometimes, rebooting the router and both computers helps. In rare cases, your antivirus software may block SMB traffic—try temporarily disabling it to check.
Using specialized software (SHAREit, Resilio)
If you don't want to mess around with setting up access rights and IP addresses, P2P (peer-to-peer) programs can help. They automatically find devices on the network and create a secure channel for transmission. One of the most popular solutions is Resilio Sync (formerly BitTorrent Sync) or Chinese equivalent SHAREit (for PC).
The principle is simple: you install the program on both computers, add a folder to sync, or select a file to send. The program scans the local network and finds the second device. Transfers are made directly through the WiFi router, bypassing external servers, ensuring high speed and privacy.
The advantage of such utilities is that they can work even without an internet connection, using only a local WiFi network. They automatically bypass firewall restrictions and don't require complex Windows account setup. This makes them ideal for quickly transferring files to guests or between devices running different operating systems, such as Windows and macOS.
- 🚀 High transfer speed, limited only by the power of the WiFi adapter.
- 🔐 Encryption of traffic during data transmission.
- 🔄 Ability to synchronize folders in real time.
It's worth noting that some free versions of programs may contain ads or have file size limitations. However, for home use, the functionality of the free versions is generally sufficient. The main thing is to ensure that both devices are running the same version of the app or compatible protocol versions.
Cloud storage as an intermediate link
We can't forget about cloud technologies either. Services like Yandex Disk, Google Drive or Dropbox They have desktop clients that create a virtual folder on your computer. Files placed in this folder on one computer are automatically uploaded to the cloud and synced on the second.
This method has its own nuances. The transfer speed will be limited by your internet connection, not your local WiFi network. If you have a 100 Mbps plan and your router supports 800 Mbps, the cloud method will be eight times slower than direct transfer. However, it has a huge advantage: files are saved in the cloud, creating a backup copy.
Using the cloud makes sense if computers are in different physical locations but connected to the same account, or if the data volume is small. This is the best option for archiving important documents, as it protects against data loss in the event of a hard drive failure on one of the computers.
| Method of transmission | Speed | Difficulty of setup | Internet addiction |
|---|---|---|---|
| Shared folder (SMB) | High (local) | Average | Not required |
| Special software (P2P) | Very high | Low | Not required* |
| Cloud services | Depends on the tariff | Low | Necessarily |
| FTP server | High | High | Not required |
Solution and speed optimization
Even with proper configuration, users may experience slow speeds or connection drops. Often, the problem lies with the network adapter drivers. Make sure both computers have up-to-date WiFi module drivers installed. Outdated drivers may not work correctly with modern encryption standards or frequencies.
Another cause of slow transfers could be your antivirus software. It can scan every transferred file in real time, creating a bottleneck. When transferring large amounts of data, you can temporarily suspend protection or add the transfer folder to the exceptions list.
It's also worth experimenting with the WiFi channel. If you live in an apartment building, the airwaves may be clogged with neighboring routers. Use WiFi analysis tools (such as WiFi Analyzer on your smartphone) to find a free channel and switch the router to it through the web interface. 192.168.0.1 or 192.168.1.1.
⚠️ Note: Router and operating system interfaces are constantly updated. Menu locations and item names may differ from those described in the instructions. Always consult the official documentation for your equipment if you cannot find the setting you need.
You can use the built-in network troubleshooter to diagnose problems. Right-click the network icon in the system tray and select "Diagnose." Windows will attempt to automatically flush the DNS cache, restart the adapter, and fix TCP/IP protocol errors.
Frequently Asked Questions (FAQ)
Is it possible to transfer files if the computers are running different versions of Windows?
Yes, the SMB protocol is universal. You can easily transfer files between Windows 10, Windows 11, Windows 7, and even macOS or Linux. However, additional settings may be required to support older encryption protocols if one of the computers is very old.
Why is the WiFi transfer speed much lower than what is stated on the router?
Actual WiFi speed is always lower than theoretical due to protocol overhead, interference, and distance to the router. Furthermore, the speed reported is for the sum of all devices on the network. If the router reports 1200 Mbps, the actual speed on a single device under ideal conditions will be 600-800 Mbps, and in practice, even lower.
Is it safe to leave a shared folder open?
If you're on a home network with a strong WiFi password, the risks are minimal. However, if outsiders might connect to your network, it's best to set a password on the shared folder itself or use a Windows guest profile with limited privileges.
How to speed up the transfer of many small files?
Transfer protocols spend a lot of time processing the headers of each file. The best solution is to pack thousands of small files (photos, documents) into a single archive (ZIP or RAR) before sending. This will reduce transfer time significantly.
Does this method work without internet access?
Yes, the internet is not required for a local network (SMB, P2P software) to function. It is sufficient for the router to be turned on and create a local network to which both computers are connected. In this case, the router simply acts as a switch.
