1. What is My Public Wi-Fi and when to use it

My Public Wi-Fi — a free utility for Windows (from Windows 7 to Windows 11), which creates a virtual access point (SoftAP) without having to access the registry or command line. The program supports:

• 🔄 Distribution of any type of connection: cable (Ethernet), mobile (3G/4G/5G), even VPN tunnels.
• 🔒 Security settings: select encryption type (WPA2-PSK, WPA-PSK, WEP), hiding SSID, filtering MAC addresses.
• 📊 Traffic monitoring: display of connected devices, consumed traffic and blocking by IP/MAC.
• 🚫 Blocking websites: via the built-in DNS proxy (for example, to restrict access to social networks).

The main advantage over the built-in mobsync In Windows, it's stability. The built-in feature often crashes after updates or reboots, while My Public Wi-Fi Saves settings and automatically restores the access point. However, there are some downsides:

• ⚠️ Limit on the number of devices: in the free version - up to 10 connections simultaneously (in Connectify Hotspot, for example, the limit is lower - 5 devices).
• ⚠️ Advertising in the interface: The free version displays banners (they can be disabled by purchasing Pro versions for ~$20).
• ⚠️ Dependency on Wi-Fi adapter drivers: on some laptops (especially with adapters Realtek) the access point may work unstably.

When to choose My Public Wi-Fi:

• 💻 Need to share internet from a laptop to a smartphone, tablet, or second PC.
• 🏢 Set up a temporary network in your office/cafe without buying a router.
• 🔍 Test your devices' Wi-Fi connections before setting up your main router.
• 🛡️ Set up guest access with restrictions (for example, blocking torrents).

⚠️ Attention: If you use My Public Wi-Fi If you want to share your internet in a public place (such as a hotel or restaurant), make sure it doesn't violate your internet service provider's terms and conditions. Some providers (such as Rostelecom or Beeline) prohibit the resale of traffic in their tariffs.

2. System requirements and PC preparation

Before installation My Public Wi-Fi Check if your computer meets the minimum requirements:

If your Wi-Fi adapter does not support the mode SoftAP (virtual access point), the program won't be able to create a network. You can check this via the command line:

netsh wlan show drivers

Look for the line Hosted network support - there should be YesIf it's worth it No, update the driver or use an external USB adapter (eg. TP-Link TL-WN725N).

Also before installation:

Update Windows to the latest version

Check for Hosted Network support in your Wi-Fi driver.

Disable the built-in Windows hotspot (if enabled)

Add My Public Wi-Fi to your firewall and antivirus exceptions

Connect an internet cable or activate mobile internet (if you are distributing 3G/4G)-->

3. Installing and turning on My Public Wi-Fi for the first time

Download the latest version of the program from official website (The distribution size is ~1.5 MB). The installation is standard, but there are some nuances:

1. Run the installer (mypublicwifi.exe) as administrator. If Windows blocks the launch, click Read more → Run anyway.

2. During the installation process, check the box Create Desktop Shortcut (create a shortcut on the desktop) and Run MyPublicWiFi on Windows startup (run at system startup).

3. After installation, the program will open automatically. If not, find it in the menu. Start or by shortcut on the desktop.

When you first launch the program, you'll be prompted to select an interface language (Russian is available). The main program window consists of three tabs:

• 📡 Setting — setting up the network name (SSID), password and encryption type.
• 👥 Clients — a list of connected devices and their activity.
• 🌐 Management — website blocking, DNS proxy setup.

To create an access point:

1. In the field Network Name (SSID) Enter the network name (eg. MyHotspot_123). Use only Latin characters and numbers.

2. In the field Network Key Create a password (at least 8 characters). We recommend using a combination of letters, numbers, and special characters (e.g., P@ssw0rd!2026).

3. In the drop-down menu Network Type select WPA2-PSK (AES) - This is the most secure encryption option.

4. Check the box Enable Internet Sharing (allow internet sharing).

4. Security Setup: How to Protect Your Network

By default My Public Wi-Fi It creates a network with basic security, but it's not enough if you're sharing internet in a public place or connecting unfamiliar devices. Here are the key security measures:

4.1. Selecting the encryption type

There are three options available in the program settings:

• 🔐 WPA2-PSK (AES) — the most reliable. Use it if all connected devices support this standard (most modern gadgets do).
• 🔓 WPA-PSK (TKIP) - less secure, but compatible with older devices (eg. iPhone 4 or Android 4.x).
• ❌ WEP — is outdated and unreliable. It can be hacked in a few minutes using Aircrack-ng. Do not use!

4.2. MAC address filtering

To allow connections only to specific devices:

1. Go to the tab Clients.

2. Find the device you want to allow access to in the list and copy it MAC address (For example, 00:1A:2B:3C:4D:5E).

3. In the file mypublicwifi.conf (located in the program folder) add the line:

allow_mac = 00:1A:2B:3C:4D:5E

To lock your device, use deny_mac.

4.3 Hiding the SSID and Limiting Visibility

If you don't want your network to appear in the list of available networks:

• 🔍 In the settings My Public Wi-Fi uncheck the box Broadcast SSID (network name broadcast).
• 📵 You will have to connect to such a network manually by specifying the SSID on your device.

You can also limit the number of connected devices. To do this, in the file mypublicwifi.conf add:

max_clients = 5

⚠️ Attention: If you are setting up My Public Wi-Fi To distribute Internet in a cafe or other public place, it is necessary to:

• 📜 Sign a contract with your provider for commercial use of traffic.
• 🔒 Set up automatic user logout after a certain amount of time (e.g. 1 hour).
• 📋 Keep a connection log (tab Clients → Export) in case of claims from copyright holders (for example, for downloading torrents).

What to do if someone hacked your hotspot?

If you notice an unknown MAC address in the list of connected devices:

1. Immediately change the network password in the settings My Public Wi-Fi.

2. Check your computer for network worms (for example, using Kaspersky Virus Removal Tool).

3. Enable traffic logging in the tab Management → Enable Logging and analyze suspicious activity.

4. If the hacking occurs again, change the encryption type to WPA3 (if supported by the adapter) or use an external router.

5. Common mistakes and their solutions

Even with the correct settings My Public Wi-Fi may operate unstably. Let's look at typical problems and how to fix them:

If none of the methods helped, try:

• 🔄 Reinstall My Public Wi-Fi with clearing the settings (delete the folder C:\Program Files (x86)\MyPublicWiFi before reinstallation).
• 🖥️ Run the program in compatibility mode for Windows 8 (right-click on the shortcut → Properties → Compatibility).
• 📡 Check if the Windows Firewall or a third-party firewall (for example, Comodo Firewall).

6. Alternatives to My Public Wi-Fi: When to Choose Another Solution

My Public Wi-Fi — isn't the only program for distributing Wi-Fi. In some cases, it's better to use alternatives:

If you use macOS or Linux, My Public Wi-Fi won't work. There are solutions for these systems:

• 🍎 macOS: built-in function Sharing → Internet Sharing (through System Preferences → Network).
• 🐧 Linux: utilities create_ap or hostapd (requires terminal skills).

Important: Starting from Windows 11 23H2, Microsoft has limited the capabilities of third-party programs for distributing Wi-Fi through Hosted Network. If My Public Wi-Fi stopped working after the update, use Connectify or set up an access point via PowerShell:

netsh wlan set hostednetwork mode=allow ssid=MyHotspot key=Password123
netsh wlan start hostednetwork

7. Optimizing connection speed and stability

If your Wi-Fi connection is slow or keeps dropping out, try the following settings:

7.1. Selecting a Wi-Fi channel

By default My Public Wi-Fi Selects a channel automatically, but it may be congested by neighboring networks. To change the channel:

1. Download the utility WiFi Analyzer (for Android) or inSSIDer (for PC) and check which channels are free.

2. In the file mypublicwifi.conf add the line:

channel = 6

Recommended channels for 2.4 GHz: 1, 6, 11 (they do not intersect). For 5 GHz Select channels 36–48 or 149–165.

7.2 Bandwidth Limitation

If one of the connected devices is hogging the bandwidth (for example, downloading torrents), you can limit the speed for all or selected clients:

• 📉 In the file mypublicwifi.conf add:

download_limit = 10240 # Download limit (in KB/s, here 10 MB/s)
upload_limit = 5120 # Upload limit (5 MB/s)

To restrict a specific device, specify its MAC address:

mac_limit = 00:1A:2B:3C:4D:5E,10240,5120

7.3 Using an external Wi-Fi adapter

Built-in Wi-Fi modules in laptops are often weak. For stable internet distribution among 10+ devices, it's better to use an external adapter, such as:

• 🔌 TP-Link Archer T4U - supports 802.11ac (up to 867 Mbps).
• 🔌 ASUS USB-AC68 - dual-band (2.4 + 5 GHz).

Connect the adapter to the USB port, install the drivers and select it in the settings My Public Wi-Fi in the field Network Adapter.

⚠️ Attention: If you are distributing the Internet via mobile network (3G/4G), the speed will be limited by your operator's tariff. For example, MegaFon And Beeline when distributing Wi-Fi it may work FUP (restriction after exceeding the traffic limit). Check the terms of your plan in your personal account.

8. Paid Wi-Fi access: setup via My Public Wi-Fi

If you want to monetize Wi-Fi distribution (for example, in a cafe or hostel), My Public Wi-Fi Allows you to set up paid access through integration with payment systems. To do this:

1. Go to the tab Management → Hotspot.

2. Check the box Enable Hotspot.

3. In the field Login Page URL Enter the address of your authorization page (you can create it on Tilda or Wix).

4. In the file mypublicwifi.conf add:

hotspot_enabled = 1
hotspot_login_url = http://your-site.ru/login
hotspot_logout_url = http://your-site.ru/logout

Example of work:

• 📱 A user connects to your network.
• 🌐 When you try to open any website, it redirects to your authorization page.
• 💳 After payment (via UKassa, Robokassa or Sberbank Acquiring) the user gets access to the Internet for a limited time.

To automate the process, you can use the following services:

• 🔗 WiFiCoin — a ready-made solution for paid Wi-Fi with a personal account.
• 🔗 MyWiFi — a cloud platform for hotspot management.

It is important to consider the legal aspects:

• 📜 In Russia, distributing paid Wi-Fi is considered telecommunications service and requires a license if income exceeds 200 thousand rubles per year (Article 50 of Federal Law No. 126-FZ).
• 📋 It is necessary to keep a connection log (IP, MAC, time) for 6 months (requirement Roskomnadzor).

If you're sharing internet in a public place, some websites (such as Telegram or LinkedIn) may be blocked by Roskomnadzor. To bypass these blocks:

1. Set up My Public Wi-Fi for use DNS from Google (8.8.8.8) or Cloudflare (1.1.1.1) in the tab Management → DNS Settings.

2. Or connect the VPN on the computer that distributes Wi-Fi (for example, ProtonVPN or NordVPN).
