☑️ Diagnostics in Windows
Working with wireless adapter driversThe most common reason for Wi-Fi not working on Lenovo 320 The problem is missing, incorrectly installed, or corrupted drivers. The IdeaPad 320 series was equipped with modules from various manufacturers: Realtek RTL8723BE, Qualcomm Atheros QCA6174 or Intel Dual Band WirelessFor stable operation, it is critical to use the correct driver version for your specific network controller.
To find out the exact adapter model, open Device Manager (right-click Start and select "Device Manager"). Expand the "Network Adapters" tab. If you see a device with a yellow exclamation point or "Unknown Device," the driver is missing. If you see a device named "Wireless" or "Wi-Fi" but it's not working, try updating its firmware using the context menu.
Where can I download the driver if I don't have internet access?
Use your smartphone with a USB cable. Enable USB tethering on your phone (usually in the hotspot settings). Your computer will detect your phone as a network card and access the internet to download drivers from the official Lenovo website.
The best solution is to download drivers from the official Lenovo support website. Enter your laptop's serial number (found on the sticker on the bottom) in the search field on the website, select your operating system, and download the file labeled "WLAN" or "Wireless LAN." Installing drivers from third-party sources may result in unstable operation or complete module failure, as digital signature Lenovo drivers often have specific requirements.
⚠️ Please note: The Lenovo support website interface and driver section structure may change. If you can't find the required file by model, use the automatic driver scanner offered on the website or search for the driver by the exact hardware ID in Device Manager.
Power management and energy savingWindows' power management system often aggressively disables the Wi-Fi module to conserve battery life, resulting in connection drops or failure to connect to the network after waking from sleep mode. To prevent the system from disabling the adapter, open Device Manager again, locate your wireless adapter, right-click it, and select "Properties."
In the window that opens, go to the "Power Management" tab. Here you will see a checkbox next to "Allow the computer to turn off this device to save power." Uncheck it and click OK. This action will force network interface operate in constant mode, which is especially important for the Lenovo 320 model, which is known for its sensitivity to power settings.
It's also worth checking the power plan in Control Panel. Select the "High Performance" plan, as the "Power Saver" mode may software-limit the Wi-Fi transmitter power, reducing the range and connection stability. After changing the settings, it's recommended to restart the laptop for the changes to take effect.
Windows Services and System SettingsWireless networks in Windows are controlled by a special service that must be running and set to automatic. If the "WLAN Autoconfig" service is stopped, you won't be able to enable Wi-Fi using any buttons. You can check its status using the command services.msc, entered into the Run window.
Find the WLAN-related service in the list, double-click it, and ensure the startup type is set to "Automatic" and the service is running. If it is stopped, click "Start." This service often malfunctions after installing system optimizers or viruses that block network activity.
It's also worth checking network services via the command line. Launch Terminal as administrator and reset network settings with the command netsh winsock resetThis action clears the network socket cache and often resolves issues where drivers are installed but a connection fails. A reboot is required after running this command.
Diagnostics via BIOS and resetting settingsIn rare cases, the wireless module may be disabled at the BIOS/UEFI level. This can happen after a BIOS reset or an unsuccessful motherboard firmware update. To check, enter the BIOS by pressing the [key] F2 or Fn + F2 When turning on the laptop. In some Lenovo 320 models, the BIOS is accessed via the recessed Novo Button on the side of the case.
In the BIOS menu, go to the section Configuration or Security and find the item related to Wireless LAN or Onboard WLAN Device. Make sure it is in the state EnabledIf the module is disabled here, the operating system will simply not detect the presence of Wi-Fi equipment.
If software methods don't help, you can perform a full reset of the BIOS settings to factory defaults (Load Optimal Defaults), but this should be done with caution. The Lenovo 320 also features a "hard reset" (Power Cycle): unplug the charger, remove the battery (if the model supports it) or disconnect the battery cable inside the case, then hold the power button for 30 seconds. After powering up, the system will perform a self-test and may restore the module's functionality.
