The modern pace of life dictates its own rules, and the need for instant access to documents, photos, or films on different devices is becoming the norm.
When you don't have a USB cable at hand and you need to transfer files urgently, a wireless network comes to the rescue.
Many users still use flash drives or external hard drives without realizing that local area network can work much faster and more conveniently.
In this article, we'll explore proven methods for exchanging data between a desktop PC and a laptop, using only the capabilities of your router and operating system.
The transmission speed depends not only on the standard Wi-Fi, but also on the network equipment settings, so it is important to properly prepare both devices.
You'll learn how to create shared folders, set up FTP servers, and use built-in Windows tools for seamless access to data.
Preparing equipment and checking the network
Before you begin setup, make sure both devices are connected to the same wireless network.
This is a critical point: if the computer is connected to the guest Wi-Fi and the laptop is connected to the main Wi-Fi, or one of them is using mobile Internet, a direct connection will not be established.
Check the connection status in the system tray or network settings.
Make sure your network type in Windows is set to Private (Private), not as Public.
In a public profile, the system automatically blocks detection of the device by other gadgets for security purposes.
To switch, go to network settings and select the appropriate profile.
It's also worth checking the IP addresses of your devices to make sure they're on the same subnet.
Typically, routers issue addresses like 192.168.1.x or 192.168.0.x, where x is a unique number for each gadget.
If the addresses start with different numbers (for example, 192.168.1.x and 10.0.0.x), then the devices are isolated from each other.
Setting up folder sharing in Windows
The simplest and most native way to transfer data is to use the built-in shared folder mechanism.
This method does not require installation of third-party software and works stably in the environment Windows 10 And Windows 11.
First, select the folder you plan to share, right-click on it and select "Properties."
In the window that opens, go to the "Access" tab and click the "Advanced settings" button.
Check the box next to "Share this folder."
Next, you need to set up permissions: click the “Permissions” button and make sure that the “Everyone” group or a specific user has permissions to Reading and, if necessary, on Change.
☑️ Check access settings
After setting up permissions, it is important to check the network profile.
Go to Control Panel → Network and Sharing Center → Change advanced sharing settings.
In the "Private" section, enable the "Turn on network discovery" and "Turn on file and printer sharing" options.
⚠️ Attention: If you are in a public place (cafe, coworking space), do not enable sharing without a password, as your files may become visible to strangers on the same network.The folder is now available for connection from another device.
On your laptop, open File Explorer and enter in the address bar
\\Computer IP addressor\\Computer-name.The system may request credentials: enter the login and password for the user account on the computer where the folder is located.
Using FTP for fast transfers
For those who prefer more flexible tools, creating your own is a great solution. FTP servers.
This method is often more stable than the standard Windows SMB protocol and allows you to use convenient file managers.
You will need to install a lightweight server, such as FileZilla Server, on the source computer.
After installation, run the program and create a new user in the settings.
Give it a password and specify the path to the root directory from which the files will be taken.
It is important to allow the user read and write permissions if you plan to not only retrieve but also download files to your PC.
Why is FTP better than a standard folder?
FTP is less demanding on Windows network settings and is less likely to be blocked by antivirus software or firewalls when transferring large amounts of data. It also allows you to resume interrupted downloads, which is critical when Wi-Fi is unstable.
On your laptop, use any FTP client or even the built-in file explorer to connect.
In the address bar, enter
ftp://computer-IP-address.Enter the login and password you specified in the server settings.
Now you see your computer's file system as a regular disk.
You can drag and drop files, copy entire directories, and see the transfer progress.
The speed in this mode is often higher, as the protocol is optimized for streaming data.
Comparison of data transfer methods
The best method to choose depends on your needs, file size, and technical expertise.
Below is a table that helps compare the main characteristics of the methods considered.
Method Speed Difficulty of setup Security Shared folder (SMB) High Average Medium (depending on password) FTP Server Very high High Low (no encryption) Cloud services Depends on the tariff Low High Specialized software High Low Average As you can see from the table, Windows' built-in tools offer a good balance between speed and convenience.
However, for regular work with large archives, FTP is better suited.
If maximum simplicity is important and you are willing to sacrifice speed for convenience, you can use the cloud.
Third-party file sharing programs
If you don't want to mess around with Windows settings, specialized utilities will come to the rescue.
Programs like Send Anywhere, Feem or Resilio Sync create their own secure network on top of your Wi-Fi.
They automatically find devices on the local network and allow you to transfer files by simply dragging and dropping.
The advantage of such solutions is their cross-platform nature.
You can easily transfer a file not only to a laptop, but also to a smartphone or tablet running Android or iOS.
The interface of such programs is usually minimalistic: you select a file, see a 6-digit code or the name of the recipient's device, and confirm receipt.
⚠️ Attention: Free versions of such programs often have limitations on the size of a single file or transfer speed, forcing a paid subscription to remove the limits.Some utilities use P2P technology, which means that data is transferred directly between devices without being uploaded to third-party servers.
This provides high speed comparable to the bandwidth of your router.
However, make sure you download the program from the developer's official website to avoid the introduction of malicious code.
Cloud storage as an alternative
Cloud technologies, which have become the de facto standard for synchronization, cannot be ignored.
Services like Google Drive, Yandex Disk or Dropbox allow you to download a file to your computer and it will automatically appear on your laptop.
This is not exactly a direct Wi-Fi transfer between devices, as the data goes through an internet channel.
However, if you have a fast tariff, this method is extremely convenient.
You don't need to keep both devices turned on at the same time: download a file to your PC during the day and download it to your laptop in the evening at a cafe.
The main disadvantage is the dependence on the speed of your Internet channel and the presence of disk space limits.
For large amounts of data, such as a 100GB system backup, the cloud may be inconvenient due to long loading times.
In this case, local transfer via Wi-Fi via a shared folder or FTP will be much more efficient.
Choose a tool based on the size of the data and internet access.
Solution and speed optimization
Sometimes users experience slow copying speeds or connection interruptions.
A common cause is the use of an outdated Wi-Fi standard. 802.11n (2.4 GHz) instead of the modern one ac or ax (5 GHz).
The 2.4 GHz band is heavily congested with neighboring routers and household appliances, which causes interference.
Check if your devices are connected to the 5GHz network if your router supports dual-band operation.
Also make sure that there are no thick concrete walls or metal structures between the computer, laptop and router.
Distance plays a key role: the closer the devices are to the signal source, the higher the stability.
⚠️ Attention: Antivirus and firewall software may be blocking the connection. If the devices can't see each other, try temporarily disabling protection or adding an exception for "Private Networks."Another nuance is the power saving settings of the Wi-Fi adapter.
Windows may turn off the adapter to save power, which causes the connection to drop when transferring large files.
Go to Device Manager, find your wireless adapter, open its properties, and in the Power Management tab, uncheck the box next to Allow Disable.
Following these simple rules will help you achieve the maximum speed available from your equipment.
Please remember that actual Wi-Fi speed is always lower than the stated theoretical speed due to protocol overhead and signal quality.
However, even at average speeds, wireless transmission is more convenient than constantly running around with flash drives.
Why can't the computer see the laptop on the network?
Most often, the issue is with the network profile. Make sure the network is marked as "Private" on both devices. Also, check that "Network Discovery" is enabled in Advanced Sharing Settings. Sometimes, simply restarting the "Function Discovery Resource Publishing" service in Windows Services helps.
What is the maximum transfer speed for Wi-Fi?
Speed depends on the router and adapter standards. For 2.4 GHz, actual speeds rarely exceed 4-6 MB/s. In the 5 GHz band (AC standard), speeds of 20-50 MB/s and higher can be achieved if devices support wide channels and MIMO technology.
Is it safe to share passwords through a shared folder?
Transferring data within a home network is relatively secure if you have a password on your Wi-Fi (WPA2/WPA3 protocol). However, data within the SMB protocol may not be encrypted. For transferring critical data, it's best to use a password-protected archive or dedicated encrypted channels.
