How to distribute the Internet from a laptop to a PC: all methods with settings

Turning a laptop into an access point for distributing the Internet to another computer is easier than it seems. This feature is useful if you do not have a router and only one device is connected to the network. For example, when the Internet comes through USB modem, Ethernet cable or mobile hotspot on a smartphone connected to a laptop.

This article contains proven methods for Windows 10/11, macOS And Linux, including solutions for cases where standard tools do not work. We'll look at settings through the command line, third-party programs, and even options for safe distribution without loss of speed. And at the end there are answers to frequently asked questions and a table comparing methods.

1. Internet distribution via “Mobile hotspot” in Windows

The easiest way is to use the built-in function Mobile hotspot, available in Windows 10/11. It does not require installation of additional software and works stably if the drivers Wi-Fi adapter updated.

To activate the distribution:

1. Open Settings → Network and Internet → Mobile hotspot.
2. In the field Internet Connection Sharing select a source (eg Ethernet or Wi-Fi).
3. Click Editto set the network name (SSID) and password (minimum 8 characters).
4. Toggle the slider Allow use of my internet connection to position On

If the connected PC does not see the network, check:

• 🔄 Antivirus or firewall — they can block the distribution. Disable them temporarily.
• 📡 Wi-Fi range — in the adapter settings (in Device Manager) select 802.11n instead of 802.11ac, if the devices are not compatible.
• 🔌 Power Saving Mode - disable it for the Wi-Fi adapter in Control Panel → Power Options.

⚠️ Attention: If after activating the hotspot the Internet on the laptop disappears, check whether there is a conflict IP addresses online. Manually set an IP from the range on your PC 192.168.137.x (For example, 192.168.137.10).

2. Distribution via command line (CMD)

If the built-in hotspot does not work or you need advanced settings (for example, change Wi-Fi channel), use command line. This method is universal and works even on older versions of Windows.

Open CMD as administrator and run the commands in order:

netsh wlan set hostednetwork mode=allow ssid="Название_сети" key="Пароль" keyUsage=persistent
netsh wlan start hostednetwork

To enable sharing:

1. Open Control Panel → Network and Sharing Center → Change adapter settings.
2. Find the connection through which the laptop receives the Internet (for example, Ethernet), right click → Properties → tab Access.
3. Check the box Allow other network users to use your Internet connection and select the created network (LAN connection* X).

To stop distribution, enter:

netsh wlan stop hostednetwork

Make sure that the Wi-Fi adapter supports hostednetwork (check with the command netsh wlan show drivers)

Disable other network management programs (such as Hamachi or Connectify)

Check that the adapter settings are enabled Ad Hoc (if used)

Set a password that is at least 8 characters long (otherwise the network will not be created) -->

⚠️ Attention: After rebooting the laptop, distribution via hostednetwork turns off. To automate the launch, create .bat-file with commands and add it to Autoload.

3. Internet distribution from macOS to PC

On MacBook or iMac You can distribute the Internet through Sharing. This method works to transfer the connection over Wi-Fi, Ethernet or even Thunderbolt.

Instructions:

1. Open System Preferences → Sharing.
2. From the left menu select Shared Internet.
3. In the field General connection indicate the source (for example, Wi-Fi or Ethernet).
4. B For computers using mark Wi-Fi (or Ethernet, if you connect via cable).
5. Click Wi-Fi Settings and set:
   • 📛 Network name (For example, MacHotspot)
   • 🔒 Channel (recommended 6 or 11 for minimal interference)
   • 🔑 Password (minimum 8 characters, security type WPA2/WPA3)

If the PC does not connect:

• 🔄 Reboot Wi-Fi adapter on Mac (System Settings → Network → Wi-Fi → Disable/Enable).
• 🛡️ Disable firewall in System Settings → Security and Safety → Firewall.
• 📡 Check that it is not manually registered on the PC static IP — it should be obtained automatically (DHCP).

4. Distribution via Ethernet cable (LAN)

If both devices have Ethernet port, you can distribute the Internet via cable - it’s more stable and faster than Wi-Fi. Suitable for Windows, macOS And Linux.

For Windows:

1. Connect PC to Laptop network cable (regular patch cord, crossover is not needed for modern adapters).
2. On your laptop, open Control Panel → Network and Sharing Center → Change adapter settings.
3. Right click on Ethernet connection (internet source) → Properties → tab Access.
4. Check the box Allow other network users to use your Internet connection and select Ethernet (or Local network connection) in the list.

For Linux (For example, Ubuntu):

sudo nano /etc/sysctl.conf

Uncomment the line:

net.ipv4.ip_forward=1

Then do:

sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT

Where eth0 — interface with the Internet, eth1 - cable to PC.

5. Programs for Internet distribution

If standard methods do not work, use third-party utilities. They offer additional features: speed limit, device blacklist, automatic start.

Popular programs:

• 🖥️ Connectify Hotspot — paid, but with a trial period. Supports WPA3, traffic monitoring and distribution via 3G/4G modem.
• 🌐 mHotspot - free, simple, but with advertising. Powered by Windows 7–11.
• 🔗 Virtual Router Plus - open source, but may conflict with antiviruses.
• 🍎 Internet Sharing (macOS) - a built-in utility, but with restrictions on the number of devices.

Setting example Connectify:

1. Download and install the program from official website.
2. Select internet source in the field Internet to Share.
3. Set network name And password.
4. Turn on Hotspot Name and activate the distribution with the button Start Hotspot.

⚠️ Attention: Free versions of programs (for example, mHotspot) can embed advertising in traffic or collect data about connected devices. Use them only from trusted sources.

6. Solving problems with Internet distribution

If the PC does not connect or the Internet does not work, check:

1. No Internet access on the connected PC

• 🔌 Make sure your laptop is in Connection properties included Sharing.
• 🌍 Check that the network settings on your PC are set to automatic IP And DNS (Get address automatically).
• 🔄 Reboot both devices.

2. The network is visible, but does not connect

• 🔑 Check the password is correct (case is important!).
• 📡 Change Wi-Fi channel in the hotspot settings (for example, with 6 on 11).
• 🛡️ Disable VPN or proxy on a laptop.

3. Low speed or breaks

• 📶 Move the laptop closer to the PC or eliminate interference (microwaves, other routers).
• 🔧 Update your driver Wi-Fi adapter on a laptop.
• 📊 Limit the number of connected devices (optimally - no more than 5).
