• 🌐 Internet connection: the laptop must be connected to the network via Ethernet, USB modem or mobile Internet (3G/4G/5G). Sharing Wi-Fi without internet access is possible, but pointless for most purposes.
• 🔒 Administrator rights: to change network settings on Windows admin rights will be required. macOS a standard account is sufficient.

To check support SoftAP, open Command line on behalf of the administrator (on Windows) and enter:

netsh wlan show drivers

Find the line in the results Hosted network support - it should be indicated there YesIf not, update the adapter drivers via device Manager or the manufacturer's website (Intel, Qualcomm Atheros, Realtek and others).

⚠️ Attention: On some laptops with Windows 11 built-in function Mobile hotspot It may conflict with third-party Wi-Fi sharing programs. If the hotspot doesn't appear after setup, disable it in the system settings.

2. Method 1: Sharing Wi-Fi via Mobile Hotspot (Windows 10/11)

The easiest and most reliable method for users Windows — built-in function Mobile hotspotIt doesn't require any command knowledge and works reliably on most devices. Here's how to set it up:

• 🔄 Change your password regularly, if you often distribute Wi-Fi in public places (cafes, airports).
• 📡 Turn off the networkwhen it's not needed. A constantly active access point increases the risk of hacking.
• 🛡️ Set up your firewall: Allow only the necessary connections. Windows this is done in Control Panel → Windows Defender Firewall → Advanced settings.

If you're distributing Wi-Fi in an office or public space, consider additional measures:

• 🔗 Limit the number of connected devices (in programs like Connectify Hotspot there is such a function).
• ⏱️ Set an automatic shut-off timer network (for example, after 2 hours).
• 🚫 Block access to local resources laptop: in the sharing settings (Control Panel → Network and Sharing Center → Change advanced sharing settings) select Turn off file and printer sharing.

⚠️ Attention: If you distribute the Internet through mobile modem (3G/4G), monitor your traffic. Some operators (for example, Megaphone or Beeline) may block distribution or charge additional fees for "inappropriate" use of the plan. Check the terms in your personal account.
