Modern users often need to quickly transfer gigabytes of information between a desktop computer and a portable device without resorting to external hard drives or cloud storage. A local area network (LAN) set up via a wireless connection allows for high-speed file sharing, limited only by the speed of your router. This solution is ideal for regularly synchronizing work projects, media libraries, or backups.
The main advantage of this method is the absence of wires and the need for additional equipment, since Wi-Fi router is already present in almost every home. However, the setup process requires attention to detail, especially if you are working in an environment Windows 10 or Windows 11, where security settings may block device discovery. Proper network configuration allows access to both computers' resources at any time.
In this article, we'll walk you through every step of setting up a connection, from checking network profile settings to creating shared folders. You'll learn how to avoid common connection errors and ensure stable data transfer. The key condition for successful transfer is that both devices are in the same subnet with the same IP address range.
Checking hardware and network requirements
Before beginning software configuration, ensure the hardware is physically ready for local data exchange. Both devices must be connected to the same wireless router. If your desktop computer doesn't have built-in Wi-Fi, you'll need to use an external USB adapter or PCIe card.
File transfer speeds directly depend on the wireless standard supported by your router and receivers. For comfortable work with large amounts of data, we recommend using the following standards: 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6). Older standards like 802.11g can become a bottleneck, significantly reducing productivity.
Frequency range is also important to consider. The 5 GHz network offers higher speeds and is less susceptible to interference, but has a shorter range than 2.4 GHz. For data transfer between devices in the same room, the 5 GHz band is preferable.
⚠️ Note: If one device is connected via cable (Ethernet) and the other via Wi-Fi, they will still see each other, but the transfer speed will be limited by the speed of the wireless connection.
Setting up a network profile and discovery
The first software step is to change the network profile type to "Private Network". By default Windows can classify new connections as "Public," which automatically hides your computer from other devices for security purposes. This is a basic requirement for setting up sharing.
To change your profile, go to the menu Start → Settings → Network & Internet → StatusIn the connection properties section, select the "Private" network type. Then, you'll need to enable discovery features. Open the Network and Sharing Control Panel and go to "Advanced Sharing Settings."
Here you will need to enable a few key options for the current profile:
- ✅ Enable network discovery
- ✅ Enable file and printer sharing
- ✅ Allow Windows to manage HomeGroup connections
Be sure to save your changes by clicking the corresponding button at the bottom of the page. Without these steps, the operating system will ignore external connection requests, even if the IP addresses are configured correctly.
Creating a shared folder for data exchange
After setting up the network, you need to determine which resources will be available for transfer. The easiest way is to create a new folder on the disk, such as "Exchange," and configure access rights for it. This will prevent accidental transfer of system files.
Right-click the created folder and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box. In the permissions list, ensure that the "Everyone" group has read and write permissions if you plan to transfer files back and forth.
| Access level | Reading | Recording | Change |
|---|---|---|---|
| Reading | Allow | Ban | Ban |
| Recording | Allow | Allow | Ban |
| Full access | Allow | Allow | Allow |
There's also a "Security" tab, where permissions are duplicated at the NTFS file system level. If you can't open a folder from another device, check this section. Permissions must be consistent at both levels.
☑️ Check access rights
Connection via SMB protocol and IP address
The most reliable connection method is to directly enter the IP address of the target computer. Automatic discovery via "Network" in File Explorer is often unstable. First, find out the IP address of the computer where the folder is located. Click Win + R, enter cmd and in the command line type ipconfig.
Find the line labeled "IPv4 Address." Write down these numbers, for example, 192.168.1.45. On the second device (the laptop), open File Explorer and enter this address in the address bar, preceded by two backslashes: \\192.168.1.45. Press Enter.
The system may prompt you for credentials. It's important to enter the username and password of the account you're logged in to on the computer with the files. If there's no password, set one up or change your security policies to allow passwordless login (not recommended for public networks).
⚠️ Note: Operating system interfaces and menu item names may vary depending on the Windows version and updates. If you don't find an exact match, look for similar settings in the Control Panel.
Using Shared Folder and HomeGroup
Older versions of Windows had a feature called "HomeGroup" that made life much easier for users. In modern versions Windows 10 And 11 It was discontinued in favor of more flexible, yet complex, settings. However, the basic shared folder mechanism remains.
You can use the built-in "Shared Documents" folder, which is available by default when network discovery is enabled. Files placed there are visible to everyone on the local network. This is convenient for temporary sharing, but less secure for personal data.
Why did the HomeGroup disappear?
Microsoft deprecated this feature due to security vulnerabilities and low popularity among corporate users who prefer manual share configuration.
For permanent operation, it's more convenient to create a dedicated user with limited rights exclusively for network access. This will improve your system's security, as the primary account will remain protected from unauthorized network access.
Alternative methods of transferring via Wi-Fi Direct
If setting up a local network seems too complicated, you can use Wi-Fi Direct technology. It allows you to connect two devices directly, without a router. However, both network adapters must support this feature.
Windows 10 and 11 now feature Nearby Sharing. It uses Bluetooth for discovery and Wi-Fi Direct for sharing. To activate it, go to Settings → System → Shared Files and turn on the function.
This method is ideal for quickly transferring individual files or links, but is not suitable for creating a persistent network drive. Connection speeds may vary, and the pairing process requires confirmation on both screens.
Troubleshooting errors and access problems
A common issue is the "Windows cannot access..." error, which occurs even with the correct settings. This is often caused by the "Function Discovery Resource Publication" service. It should be running and set to "Automatic" startup type.
To check, click Win + R, enter services.msc and find the specified service. If it's stopped, start it. Also check the "Computer" and "Server" services. Without them running, network communication is impossible.
Another cause of blocking may be antivirus software. Many security suites have a built-in firewall that blocks incoming connections over SMB ports. Try temporarily disabling network protection or adding the local network to the exceptions list.
Why can't my computer see other devices on the network?
Most likely, your network profile is set to "Public." Switch to "Private" in the network settings. Also, check that DNS is enabled and that the SMB 1.0 protocol is working (although it's best not to enable it for security reasons).
How to increase file transfer speed over Wi-Fi?
Make sure both devices are operating in the 5 GHz band. Close any bandwidth-consuming programs (torrents, streaming). Move closer to the router to avoid packet loss and data retransmissions.
Do I need the same Windows password on both PCs?
No, passwords can be different. The main thing is to enter the correct credentials for the computer you're connecting to (the remote machine's login and password).
Is it possible to transfer files between Windows and macOS?
Yes, macOS supports the SMB protocol. On a Mac, select "Connect to Server" in Finder and enter the IP address of your Windows computer. On Windows, you can also share a folder for access from a Mac, but you'll need to configure permissions.
Is it safe to leave sharing enabled all the time?
If you're on a home network behind a router with NAT, the risks are minimal. However, on public Wi-Fi networks (such as cafes and airports), always select the "Public Network" profile to hide your PC from prying eyes.
