How to Set Up a Wi-Fi Network Between Laptops: 3 Proven Methods

Connecting two or more laptops to a local network via Wi-Fi is a challenge faced by students, office workers, or simply users who need to quickly share files without using flash drives or cloud services. This connection method allows data transfer at speeds of up to 500 Mbps (depending on the Wi-Fi standard), share printers, play online games, or even collaborate on documents. But how do you do this correctly to avoid errors and ensure a stable connection?

Many people mistakenly believe that a router is required to create a network between laptops. In fact, there are three main methods: through access point (if one of the laptops acts as a router), using ad-hoc networks (direct connection of devices) or via an existing Wi-Fi router. Each method has its own nuances, and the choice depends on your needs, operating system, and the technical capabilities of your devices. In this article, we'll cover all the methods step by step—from preparing the equipment to troubleshooting common problems.

⚠️ Important: If you plan to transmit sensitive data, make sure the network is password-protected. Open networks are vulnerable to traffic interception!

1. Preparing laptops for network creation

Before you begin setup, check that your devices meet the minimum requirements. Both laptops must have working Wi-Fi adapters (built-in or external) and support at least the standard 802.11n (better - 802.11ac or Wi-Fi 6 for high speed). Also, make sure that both devices have the latest network card drivers installed. You can check this in Device Manager (For Windows) or through Terminal (For macOS/Linux).

If you use Windows 10/11, update your system to the latest version - older builds may lack features for creating hosted network (virtual access point). On macOS check that it is turned on Internet access sharing V System Preferences → Sharing. For Linux You may need to install packages hostapd And dnsmasq.

• 🔹 Windows: Update your Wi-Fi adapter driver via Device Manager → Network Adapters.
• 🔹 macOS: Make sure that in Network settings Wi-Fi is enabled and there are no restrictions on creating networks.
• 🔹 Linux: Check support AP-mode team iw list | grep "AP".
• 🔹 General: Disable firewalls and antivirus software during setup (they may block the connection).

⚠️ Attention: On some laptops (especially with adapters) Realtek) function hosted network can be disabled at the BIOS level. If the command netsh wlan show drivers shows Hosted network supported: No, update your BIOS or use an external Wi-Fi adapter.

2. Method 1: Creating a network via an access point (Windows)

This method is suitable if one of the laptops will distribute the Internet or serve as the center of a local network. Windows This is done via the command line or the graphical interface. Let's look at both options.

Step 1: Launch the access point via the command line

Open Command prompt as administrator and run the following commands:

netsh wlan set hostednetwork mode=allow ssid="MyLaptopNet" key="Password123" keyUsage=persistent
netsh wlan start hostednetwork

Where MyLaptopNet — the network name, and Password123 — password (minimum 8 characters). To enable Internet sharing, go to Control Panel → Network Connections, find your primary connection (eg. Ethernet), right-click → Properties → Access and allow the connection to be used for Local Area Connection* X (where X is the virtual adapter number).

Step 2: Connecting a Second Laptop

On the second device, find the created network MyLaptopNet in the list of available Wi-Fi networks and connect to it by entering the password. Once connected, make sure both laptops are on the same subnet (e.g. 192.168.173.X). To do this, run the following in the command line:

ipconfig

If IP addresses are not assigned automatically, configure them manually (e.g. 192.168.173.10 And 192.168.173.11 with a mask 255.255.255.0).

The network is visible in the Wi-Fi list|The password is entered correctly|IP addresses are assigned (checked via ipconfig/ifconfig)|Internet sharing is enabled (if needed)-->

3. Method 2: Ad-hoc network (direct connection without a router)

Ad-hoc (from the Latin "for this") is a type of network where devices connect directly to each other without an intermediary (router). This method works on Windows 7/10/11, macOS And Linux, but has a speed limit (usually up to 150 Mbps, even if the adapters support 802.11ac).

Setting up on Windows:

1. Open Control Panel → Network and Sharing Center → Set up a new connection.
2. Select Setting up a wireless computer-to-computer network (V Windows 10/11 This item may be missing - use the command line).
3. Specify a network name (eg. DirectLink), security type WPA2-Personal and password.
4. Connect the second laptop to the created network.

Setup on macOS:

Open System Preferences → Sharing, select Internet access sharing and in the section For computers using: mark Wi-Fi. Click Wi-Fi settings and set up the network name, channel and password. Second MacBook Connect to this network as you would to a regular Wi-Fi.

⚠️ Attention: IN Windows 10/11 creation function ad-hoc The network has been removed via the graphical interface. Use the command line:

netsh wlan set hostednetwork mode=allow ssid="DirectLink" key="Password123" keyUsage=persistent
netsh wlan start hostednetwork

* When using the command line.

** On some adapters Intel And Broadcom.

4. Method 3: Using an existing Wi-Fi router

If you have a router, the most reliable way to create a network between laptops is to connect them to the same Wi-Fi network. This method provides high speeds (up to 1 Gbps at standard Wi-Fi 6) and minimal latency, which is important for gaming or streaming data.

Step 1: Connect both laptops to the router

Make sure both devices are connected to the same network (eg. TP-Link_5G). Check that the router has assigned them IP addresses from the same subnet (for example, 192.168.0.X). To do this, follow these steps:

• 🔹 On Windows: ipconfig (look for the line IPv4 address).
• 🔹 On macOS/Linux: ifconfig or ip a.

Step 2: Set up file sharing

To allow laptops to "see" each other, enable network discovery:

• 🔹 Windows: Open Control Panel → Network Settings → Sharing Options and turn it on Network discovery And File and Printer Sharing.
• 🔹 macOS: IN System Preferences → Sharing turn on File sharing and add folders to the shared list.
• 🔹 Linux: Install samba (sudo apt install samba) and configure the config /etc/samba/smb.conf.

⚠️ Attention: If the laptops don't see each other, check that they are on the same network. working group (Windows) or domain (macOS/Linux). By default in Windows This WORKGROUP, V macOS — computer name.

5. Checking the connection and troubleshooting

After setting up the network, check its functionality. The easiest way is to use the command ping:

ping 192.168.X.X

Where 192.168.X.X — IP address of the second laptop. If the packets pass without loss (0% loss), the connection is established correctly. If not, check the following:

• 🔹 Firewall: Temporarily disable it on both devices.
• 🔹 IP addresses: Make sure they are on the same subnet (eg. 192.168.1.10 And 192.168.1.11).
• 🔹 Drivers: Update your Wi-Fi adapter drivers (especially on Windows).
• 🔹 Wi-Fi channel: If you use ad-hoc, try changing the channel to 6 or 11 (less busy).

Typical errors and solutions:

6. Optimize network speed and security

To get the most out of your Wi-Fi network between laptops, follow these guidelines:

Speed ​​up:

• 🔹 Use range 5 GHz (less busy than 2.4 GHz).
• 🔹 Set a fixed channel (eg. 36 or 149) instead of Auto.
• 🔹 If the router supports Wi-Fi 6, turn on WPA3 And OFDMA.
• 🔹 For ad-hoc select network standard 802.11n instead of 802.11g.

Security improvements:

• 🔹 Use WPA2-PSK or WPA3 (never - WEP).
• 🔹 Turn it off WPS (vulnerable to hacking).
• 🔹 Hide the network SSID (in the router settings or when creating an access point).
• 🔹 Set up MAC filtering (allow connection only for MAC addresses of your laptops).

⚠️ Attention: If you are transmitting sensitive data (such as work documents), consider using VPN within a local network or encryption of folders (BitLocker, VeraCrypt).

7. Alternative connection methods

If Wi-Fi isn't working for some reason, consider alternative ways to connect laptops:

• 🔹 Ethernet cable: Direct connection via LAN gives speed up to 1 Gbps (needed) crossover cable or regular UTP for modern adapters).
• 🔹 Bluetooth: Suitable for transferring small files (speed up to 3 Mbps).
• 🔹 USB cable: Special cables USB-Link allow you to connect two PCs at speeds up to 480 Mbps.
• 🔹 Mobile hotspot: If one of the laptops has 4G/5G, you can share the Internet via your phone.

When to choose an alternative:

Wi-Fi isn't always optimal. For example, for transferring large files (videos, backups), it's better to use Ethernet - it is more stable and faster. Bluetooth It's convenient for syncing contacts or small documents, but not suitable for gaming or streaming video. If you need to connect laptops over a distance of more than 10 meters, consider Powerline adapters (data transmission via electrical wiring).
