1. Checking the hardware compatibility of your Lenovo laptop

Not all laptops Lenovo can distribute Wi-Fi - it depends on network adapterIf your model was released before 2015, there is a high risk that the built-in module does not support the mode. SoftAP (Software Access Point). You can check this in two ways:

The first one is through device Manager:

1. Click Win + X → select device Manager.
2. Expand the branch Network adapters.
3. Find the device with the words Wireless, Wi-Fi or Network Adapter (For example, Intel Wi-Fi 6 AX200 or Qualcomm Atheros QCA61x4).
4. Right click on it → Properties → tab Additionally.
5. Look for the parameter Wireless Mode or 802.11n Wireless ModeIf there is a mode in the drop-down list 802.11a/b/g/n/ac/ax — the adapter supports distribution.

The second way is through command line:

netsh wlan show drivers

In the results, look for the line Hosted network supportIf it says there Yes - You can distribute Wi-Fi. If No - you will need an external USB adapter (for example, TP-Link TL-WN725N).

⚠️ Attention: On laptops with Windows 11 and adapters Intel Wi-Fi 6E AX210 Manual installation of the driver version may be required 22.240.0.7 or newer - standard drivers from the Update Center often cut off the hotspot function.

2. Sharing Wi-Fi via the built-in mobile hotspot (Windows 10/11)

The easiest way is to use the standard function Mobile hotspotIt works on 90% of laptops. Lenovo, but it has limitations: a maximum of 8 connected devices and the inability to change the Wi-Fi channel (which can lead to interference).

Instructions:

1. Open Parameters (Win + I) → section Network and Internet.
2. Go to the tab Mobile hotspot.
3. In the field Sharing an Internet connection select a source (eg Ethernet or Local Area Network Connection).
4. Click Change next to Network data and ask:
   • 🔑 Network name (SSID): in Latin, without spaces (for example, Lenovo_Hotspot).
   • 🔒 Password: minimum 8 characters, with numbers and letters.
   • 📶 Network range: select 5 GHz for less interference (if the adapter supports it).

If the power button is inactive or an error appears Failed to set up mobile hotspot, follow these steps:

Check the internet connection on your main device

If the standard hotspot does not work, use command lineThis method bypasses Windows limitations and allows for flexible network settings (for example, changing the channel to reduce interference).

Step-by-step instructions:

1. Run Command Prompt as Administrator (Win + X → Terminal (Administrator)).
2. Create a network named Lenovo_WiFi and password 12345678 (replace with your own):

   netsh wlan set hostednetwork mode=allow ssid=Lenovo_WiFi key=12345678

3. Start the distribution:

   netsh wlan start hostednetwork

4. Allow internet sharing:

6. Optimizing the Wi-Fi signal on a Lenovo laptop

Weak signal is a common complaint from owners Lenovo, especially on models with a metal case (for example, ThinkPad X1 Carbon). Here's how to improve coverage:

Physical methods:

• 📍 Place the laptop in the center of the room, raise it 1–1.5 meters from the floor.
• 🚫 Remove sources of interference: microwaves, wireless mice, Bluetooth speakers.
• 🔄 Rotating your laptop 90 degrees can strengthen the signal in the desired direction (antennas are usually located on the sides).

Software settings:

• 📶 Change your Wi-Fi channel to a less crowded one (use Wi-Fi Analyzer for analysis).
• 🔧 Increase the transmit power (requires administrator rights):

  netsh wlan set hostednetwork mode=allow txpower=100

  (Meaning txpower from 1 to 100, where 100 is the maximum).

• 🔄 Update your Wi-Fi adapter firmware via Lenovo Vantage or manually.

• 🔗 Speed ​​up to 3 Mbps - enough for instant messaging, but not for video.
• 🔧 Setting: Settings → Devices → Bluetooth → Add device.

2. Via Ethernet (reverse tethering):

• 🖥️ Need a cable USB-C → Ethernet or USB-A → Ethernet.
• 🚀 Speed ​​up to 1 Gbps (limited by laptop port).
• 🔧 Setup: Connect the cable, then in Network and Control Center allow sharing for Ethernet.

• 🔒 Use a password that is long 12+ characters with mixed cases and special characters.
• 🔄 Change your password every week if you share Wi-Fi in public places.
• 🛡️ Turn on Windows Firewall and disable file and printer sharing.

Advanced settings:

• 📋 Limit the number of connected devices (in Connectify or through netsh wlan set hostednetwork maxclients=5).
• 🔍 Enable connection logging (in programs like MyPublicWiFi).
• 🚫 Block unknown MAC addresses through your router settings (if your laptop is connected to the main network).

⚠️ Attention: On laptops with Windows 11 Pro can be customized Windows Defender Firewall To block incoming connections to all ports except 80 (HTTP) and 443 (HTTPS). This will reduce the risk of attack, but may disrupt the operation of some applications.
