How to Network Two Laptops via Wi-Fi: 3 Proven Methods

Connecting two laptops to a local network via Wi-Fi is a task faced by both novice users and experienced IT professionals. This connection allows for quick file sharing, online gaming, data synchronization, or even internet sharing between devices. However, many people mistakenly believe that this requires a router or additional hardware. In fact, modern operating systems provide all the necessary tools for creating a network. direct Wi-Fi connection (ad-hoc) or the use of technologies like Wi-Fi Direct.

In this article, we will look at three main ways to connect laptops to a network: through access point (one laptop distributes Wi-Fi), with the help of computer-to-computer networks (ad-hoc) and through connecting to an existing routerEach method has its own nuances, so we will go into detail about the settings for Windows 10/11 And macOSWe'll also cover common errors and troubleshooting steps. If you plan to use the connection for transferring large files or gaming, please refer to the section on speed and stability settings.

Before you begin, make sure both laptops support Wi-Fi (most models after 2010 come with adapters). 802.11n/ac/ax). Also, check if Wi-Fi is enabled on both devices—sometimes the problem lies in trivial things, such as a disabled adapter. Device Manager.

Method 1: Creating an access point on one laptop

The most versatile method is to turn one of the laptops into Wi-Fi hotspot, to which the second one will connect. This method is suitable if you need to not only network devices but also share the internet (for example, from a laptop connected to the network via cable). Setup takes no more than 5 minutes and requires no additional equipment.

On Windows 10/11 This can be done via the command line or the graphical interface. Let's look at both options:

1.1. Configuration via the command line (universal method)

Open Command prompt as administrator (click Win + X and select the appropriate item). Enter the following command, replacing SSID to the network name, and PASSWORD for password (minimum 8 characters):

netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=12345678 keyUsage=persistent

Then activate the network:

netsh wlan start hostednetwork

If a message appears "The hosted network has started.", then the access point has been created. Now you need to allow it. Internet access sharing (if required). To do this:

1. Go to Control Panel → Network and Sharing Center.
2. Click Changing adapter settings.
3. Find the connection through which the laptop receives the Internet (for example, Ethernet), right-click and select Properties.
4. Go to the tab Access and check the box Allow other network users to share your Internet connection.
5. In the drop-down list, select the connection you created (usually it is called Local Area Connection* X).

⚠️ Attention: If the second laptop does not connect after activating the network, check whether your Wi-Fi adapter supports the mode hostednetworkSome older models (for example, with chips) Broadcom) may not work. In this case, use third-party programs like Connectify or mHotspot.

1.2. Setting up via Mobile Hotspot (Windows 10/11)

An easier way is to use the built-in function Mobile hotspot:

1. Open Settings → Network & Internet → Mobile Hotspot.
2. In the field Sharing an Internet connection select a source (eg Ethernet or Wi-Fi, if the laptop is connected to another network).
3. Click Change and set the network name (SSID) and password.
4. Enable the option Mobile hotspot.

On macOS a similar function is called Internet access sharing:

1. Open System Preferences → Sharing.
2. Select Internet access sharing in the left menu.
3. In the field General connection Please provide the source (eg. Ethernet).
4. In the section For computers using mark Wi-Fi.
5. Click Wi-Fi settings and set the network name, channel and password.
6. Enable sharing by checking the box on the left.

After this, the second laptop will be able to connect to the created network as if it were a regular router. The connection speed will depend on the Wi-Fi standard (802.11n gives up to 150 Mbps, 802.11ac — up to 867 Mbit/s).

2. Method: Computer-to-computer network (Ad-Hoc)

If you don't need to distribute the Internet, but only need a local connection between two laptops, then ad-hoc networkThis method works without a router and doesn't require one of the devices to be connected to the internet. However, it is less stable than a hotspot and may not be supported by some modern devices (such as smartphones).

2.1. Setting up an ad-hoc network in Windows

IN Windows 10/11 Creation of an ad-hoc network is carried out via the command line:

netsh wlan set hostednetwork mode=allow ssid=AdHocNetwork key=password123 keyUsage=persistent
netsh wlan start hostednetwork

However, by default such a network is created in the mode infrastructure (as an access point), not ad-hocTo force the mode, use third-party utilities, for example, Virtual Router Plus or MyPublicWiFi, where you can explicitly select the network type.

On Windows 7 The ad-hoc network is configured through a graphical interface:

1. Open Network and Sharing Center.
2. Click Setting up a new connection or network.
3. Select Setting up a wireless computer-to-computer network.
4. Set the network name, security type (WPA2-Personal (recommended) and password.
5. Check the box Save settings for this network.

Once the network is created, the second laptop will be able to connect to it via a standard Wi-Fi search. However, keep in mind that ad-hoc networks typically offer slower speeds than infrastructure networks.802.11n in ad-hoc mode it operates at speeds up to 54 Mbps).

⚠️ Attention: Some antiviruses (for example, Kaspersky Internet Security) may block ad-hoc connections, considering them potentially dangerous. In this case, temporarily disable the firewall or add an exception for the local network.

2.2. Setting up ad-hoc on macOS

On Mac Ad-hoc network creation is done through the terminal. Open Terminal and run:

sudo ifconfig awdl0 down
sudo ifconfig en0 down
sudo networksetup -setairportnetwork en0 "AdHocNetwork" password123

Where en0 - Wi-Fi interface (check its name via ifconfig), A AdHocNetwork And password123 — the network name and password. After this, the second Mac will be able to connect to it via the Wi-Fi menu.

To exchange files between laptops in an ad-hoc network, it is convenient to use built-in tools:

• 📁 Windows: turn on File and Printer Sharing V Network and Control Center and open access to the required folders through Properties → Access.
• 🖥️ macOS: activate File sharing V System Preferences → Sharing and add folders to the allowed list.

Method 3: Connecting via an existing router

If both laptops are connected to the same Wi-Fi router, they are automatically on the same local network. However, file sharing or gaming requires additional configuration. network environmentThis method is the most reliable, as the router provides a stable connection and high speed (up to 1 Gbps when using 802.11ac or Wi-Fi 6).

3.1. Checking the connection to one network

Make sure both laptops are connected to the same Wi-Fi network. To do this:

• 📶 On Windows open Command line and enter ipconfig /allFind the line Main gateway — The IP address must match on both devices.
• 🍎 On macOS perform in Terminal team netstat -nr | grep defaultThe gateway address must also be the same.

If the gateways are different, but the networks are the same, check if the router is in the "Unattended mode" mode. AP Isolation (Client Isolation) - it blocks communication between devices on the local network. Disable it in the router settings (usually in the Wireless Settings or Advanced).

3.2. Setting up file sharing

To make laptops "see" each other on the network:

For Windows:

1. Open Control Panel → Network Settings → Sharing Options.
2. Turn on Network discovery And File and Printer Sharing for profile Private.
3. Turn it off Password-protected sharing (unless additional security is required).
4. Right click on the folder you want to share, select Properties → Access → Share.

For macOS:

1. Open System Preferences → Sharing.
2. Turn on File sharing and add folders to the list.
3. IN Parameters select AFP or SMB as a protocol.
4. Click Parameters and turn it on General access for guest users (if necessary).

After this, the folders will become available via network paths:

• 🖥️ In Windows open Conductor and enter in the address bar IP address of the second laptop (For example, \\192.168.1.100).
• 🍏 On Mac V Finder click Go → Connect to server and enter smb://IP address.

⚠️ Attention: If the laptops can't see each other, check that they are on the same subnet. For example, if they have the same IP address 192.168.1.100, and the other one 192.168.0.101, they won't be able to communicate. Correct this in the router settings (DHCP) or manually assign IP addresses from the same subnet.

4. Checking the connection and troubleshooting

After setting up the network, it's important to test its functionality. Let's start with basic diagnostics:

4.1. Commands for checking the connection

Open Command line (Windows) or Terminal (macOS) and run:

ping the IP address of the second laptop

For example:

ping 192.168.1.101

If the packets pass without loss (0% loss), the connection works. If not, check:

• 🔌 Firewall: temporarily disable it on both laptops.
• 📡 Wi-Fi adapters: update drivers via device Manager.
• 🔄 Network mode: Make sure the network is marked as Private (Not Public).

If ping It doesn't work, but the laptops are connected to the same network. Check the settings. IPv4:

1. On Windows open Properties network adapter and select Internet Protocol version 4 (TCP/IPv4).
2. Check the box Obtain an IP address automatically (if the router distributes DHCP).
3. If the IP is set manually, make sure the subnet mask is the same (usually 255.255.255.0).

4.2. Typical errors and solutions

If the problem is not solved, try reset network settings:

• 🪟 Windows: Settings → Network & Internet → Network reset.
• 🍎 macOS: delete the file /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist and restart your laptop.

What should I do if folder sharing isn't working?

If folders do not open despite correct settings, check:

1. Access rights: on Windows V Properties → Security add a user Everyone with rights Read/Write.

2. Protocols: on macOS V Public access turn on SMB (for compatibility with Windows).

3. Antivirus: some programs (for example, Avast) block network folders. Add them to the exceptions.

5. Optimizing connection speed and stability

If your network is working but your file transfer speed is slow, try the following optimization methods:

5.1. Selecting the right Wi-Fi channel and standard

Connection speed directly depends on:

• 📶 Wi-Fi standard: 802.11ac (5 GHz) faster 802.11n (2.4 GHz).
• 🎯 Channel: In the 2.4 GHz range, select channels 1, 6 or 11 (they do not overlap).
• 📡 Signal strength: The closer the laptops are, the more stable the connection.

To change the channel on the access point (Windows):

1. Open device Manager and find the Wi-Fi adapter.
2. IN Properties go to the tab Additionally.
3. Find the parameter Channel or Channel and set the value manually.

On the router, the channel is changed in the web interface (usually 192.168.1.1 or 192.168.0.1) in the section Wireless Settings.

5.2 Using 5 GHz for high speed

Range 5 GHz provides higher throughput but shorter range. If your laptops support 802.11ac or Wi-Fi 6, switch to this range:

• 🪟 On Windows When creating an access point, specify a channel in the range 36-165.
• 📡 Enable a separate network for 5 GHz in the Wi-Fi settings on your router.

Important: Some older devices (such as laptops built before 2012) do not support 5 GHz. In this case, use 2.4 GHz, but choose the least crowded channel.

5.3. Configuring QoS for traffic prioritization

If you use the network for gaming or video streaming, turn on QoS (Quality of Service) on the router. This feature allows you to prioritize traffic, reducing latency. The setting is located in the QoS or Traffic Control router web interface.

For access points on Windows QoS is configured via Group policy (gpedit.msc), but this is only relevant for corporate editions of the OS.

6. Local Wi-Fi network security

A local network between laptops can become vulnerable if security measures aren't taken. This is especially true when sharing internet via an access point.

6.1 Password protection and encryption selection

Always use WPA2-Personal (AES) or WPA3 To protect your network, avoid outdated protocols:

• ❌ WEP - can be easily hacked in a few minutes.
• ❌ WPA-TKIP - vulnerable to attacks.
• ✅ WPA2-AES — the optimal choice for most devices.
• ✅ WPA3 — the most secure, but not supported by all older devices.

The password must be complex (at least 12 characters, with numbers and special characters). Avoid obvious combinations like 12345678 or qwerty.

6.2. Hiding the network (SSID)

Hiding the network name (SSID) doesn't provide complete protection, but it reduces the chance of an accidental connection. To hide a network:

• 🪟 On Windows When creating an access point, add the parameter ssid=hidden=1 (not all adapters support it).
• 📡 Disable the option on your router Broadcast SSID.

To connect to a hidden network on the second laptop, enter its name and password manually in the Wi-Fi settings.

6.3. MAC address filtering

This method allows you to allow connections only to specific devices. Find MAC addresses Wi-Fi adapters of both laptops:

• 🪟 Windows: ipconfig /all (look for Physical address in the section Wireless adapter).
• 🍏 macOS: ifconfig en0 | grep ether (Where en0 — Wi-Fi interface).

Then add these addresses to the whitelist on your router or in your access point settings (if supported).

⚠️ Attention: MAC addresses can be spoofed, so this method isn't 100% secure. Use it in conjunction with a strong password and encryption. WPA2/WPA3.

7. Alternative ways to connect laptops

If your Wi-Fi connection is unstable or unavailable, consider these alternatives:

7.1 Connection via Ethernet (LAN)

The most reliable and fastest way is to use network cableTo do this:

1. Connect the laptops with a cable Ethernet (direct or crossover if ports do not support Auto-MDI/MDIX).
2. Configure IP addresses manually (e.g. 192.168.1.1 And 192.168.1.2 with a mask 255.255.255.0).
3. Share files as described in section 3.2.

The speed via cable reaches 1 Gbps (For Gigabit Ethernet), which is 10 times faster than Wi-Fi.

7.2. Bluetooth connection

If Wi-Fi is not available, you can use Bluetooth for file transfer or remote control. However, the speed will be low (up to 3 Mbps For Bluetooth 4.0).

To connect:

1. Turn on Bluetooth on both laptops.
2. Make devices discoverable.
3. On one of the laptops, send a pairing request.
4. Confirm the code on both devices.

To transfer files, use:

• 🪟 Windows: Settings → Devices → Send files via Bluetooth.
• 🍏 macOS: Drag and drop files onto the Bluetooth icon in Finder.

7.3. Remote control programs

If the goal is not file transfer, but remote control, use specialized programs:

• 🖥️ TeamViewer — for remote desktop.
• 📁 Resilio Sync — to synchronize files over a local network.
• 🎮 Parsec - for streaming games.

These programs automatically configure the network and encrypt traffic, which simplifies the process.
