Also, check your smartphone's battery level, as tethering significantly increases power consumption.
Preparing your smartphone for modem mode
The first step is always setting up a signal source. Android and iOS interfaces differ, so the steps will depend on your ecosystem. Android users need to find the section in the settings menu, most often called "Connections," "Network & Internet," or simply "Access Point." Here, activate the data sharing slider.
It's important to set a strong password and network name in advance to prevent unauthorized devices from connecting to your internet. It's best to replace standard names like "AndroidAP" with unique ones, and make the password more complex than "12345678." This will protect your personal data from being intercepted.
- 📱 Open Settings and find the "Wi-Fi Hotspot" or "Tethering & Personal Hotspot" section.

In some cases, especially on older models Lenovo ThinkPad or IdeaPad, you may need to manually switch the network security type. If your laptop sees the network but won't connect, try changing the encryption standard in the router properties (on your phone) from WPA3 to a more compatible one WPA2-PersonalThis often solves driver compatibility issues.
It's also worth paying attention to the frequency range. Modern smartphones can distribute internet at 5 GHz, which is faster, but older Wi-Fi adapters on laptops may simply not detect this frequency. In this case, you'll need to force the range in the phone's hotspot settings. 2.4 GHz.
Configuring network settings in Windows
Sometimes automatic IP address acquisition fails, and the laptop Lenovo can't access the internet even though the connection is established. In this case, you need to check the protocol settings. TCP/IPv4To do this, open "Settings" from the Start menu and go to the "Network and Internet" section.
In the window that opens, select "Change adapter settings" or "Advanced network settings." Find your wireless connection, right-click it, and select "Properties."

| Parameter | Recommended value | Description |
|---|---|---|
| Get an IP address | Automatically | Allows the phone to give an address to the laptop |
| Get DNS | Automatically | The operator's DNS servers are used |
| Alternative DNS | 8.8.8.8 | Google server (if the main one is not working) |
| Private DNS | Disabled | Often blocks work via mobile network |

Right-click the Start button and select Device Manager. Expand the Network Adapters branch. Find the device whose name contains the words Wireless, Wi-Fi, 802.11 or the brand of the chip manufacturer (for example, Intel, Realtek, Qualcomm). If there is a yellow exclamation mark next to the device, the driver is not working properly.
- 🔍 Right-click on the adapter and select "Uninstall device".
- 🔄 In the top menu, select "Action" → "Update hardware configuration".
- 💻 The system will attempt to reinstall the standard driver.
- 🌐 If this doesn't help, download the latest driver from Lenovo's official website.
A common issue is power management settings. Windows may disable the Wi-Fi module to save power, which interferes with stable operation. In the adapter properties (Power Management tab), uncheck "Allow the computer to turn off this device." This ensures that the module is always running.
⚠️ Attention: Don't install drivers from dubious aggregator sites. Use only the official support portal. Lenovo or the built-in Windows Update center to avoid viruses and system instability.
Using a USB cable to share the Internet
If the wireless connection is unstable or the Wi-Fi module on the laptop Lenovo If the laptop is faulty, you can use a wired connection via USB cable. This method provides higher speeds and lower latency (ping), which is critical for video calls or online gaming. Furthermore, the phone can be charged simultaneously by the laptop in this mode.
To begin, connect your smartphone to your laptop using a high-quality data cable (not all cables support data transfer; some only charge). On your Android device, in the "Tethering & Hotspot" menu, enable "USB Tethering." iPhone When connecting to a PC, you need to click "Trust this computer" on the phone screen.

Does the phone get very hot when sharing the Internet?
Yes, active data transfer and radio module operation cause the smartphone's casing to heat up. It is recommended to remove the phone's case for better heat dissipation and avoid placing the phone on soft surfaces while sharing.
How can I find out who is connected to my internet?
The hotspot settings on most smartphones (under the "Connected Devices" section) display a list of all devices using your data plan. You can also block them or change the password to force reconnections.
