Laptops of the series Lenovo IdeaPad B560 While these routers have proven themselves to be reliable workhorses, managing the wireless modules in this model has its own unique challenges. Users often encounter a situation where the connection indicator doesn't light and the list of available networks remains empty, causing confusion. Understanding the logic behind the hardware switches and software settings in Windows 7 or Windows 10 will allow you to quickly restore internet access.
In this article, we'll cover all possible methods for activating the module in detail, from physical buttons to deep operating system settings. Particular attention will be paid to the utility. Lenovo Energy Management, which often disables the adapter to save power. You'll learn how to diagnose the problem and fix it without calling a service center.
Please note that software and drivers may vary depending on the year of manufacture of your device and the operating system installed. Utility interfaces sometimes change, so it's always a good idea to check with the manufacturer's official support resources if standard solutions don't work.
Physical switch and hotkeys
The first and most obvious step is to check the physical condition of the wireless module. On the laptop case IdeaPad B560 There's a dedicated mechanical switch that completely disconnects the antenna's power supply. It's usually located on the front panel, near the right edge, next to the status indicators. If this switch is in the "Off" position, no software methods will enable Wi-Fi.
After checking the mechanics, you need to pay attention to the function keys. In the line Lenovo The combination of controls for wireless interfaces is traditionally responsible Fn + F5. When you press this combination, the Device Manager window should appear on the screen, where you can activate or deactivate Wireless LAN And BluetoothIf pressing does not produce a response, the keyboard driver or control utility may not be installed correctly.
Sometimes users forget that the key Fn It may be locked or inverted in the BIOS. In this case, trying to press F5 without holding down Fn may refresh the browser page or perform another action, but will not turn on Wi-Fi. Try pressing both keys simultaneously and holding them for about a second.
⚠️ Attention: If the Wi-Fi indicator on the case is blinking but not constantly on, this may indicate an attempt to connect or problems with the signal, rather than a disabled module.
Software control via Lenovo Energy Management
A key element of the ecosystem Lenovo is a utility Energy ManagementIt intercepts power management for wireless adapters and can force them to shut down to extend battery life. You can find this program's icon in the notification area (tray) next to the clock. It looks like a green battery or the Lenovo logo.
Clicking the icon opens the main window, where you can navigate to the wireless settings section. Here you'll see sliders or switches for Wi-Fi and Bluetooth. If the Wi-Fi slider is moved to the "Off" position, the system automatically disables the adapter, ignoring other settings. This often happens after reinstalling Windows, when the utility is installed automatically along with the drivers.
Also in the settings Energy Management "Maximum Performance" or "Maximum Power Saving" mode may be activated. In "High Performance" mode, the system may shut down the module when the battery is low. It is recommended to use "Balanced" or "High Performance" mode if you are near a power source.
In some operating system versions, especially Windows 10 and 11, built-in controls may conflict with the older version of the utility. If you can't find the switch in the program, try running it as an administrator. To do this, right-click the shortcut and select the appropriate option from the menu.
Configuring a network adapter in Windows
If the physical buttons and manufacturer utilities are configured correctly, but there's no internet connection, the problem may lie in the operating system settings. In Windows, network connections are managed through the Control Panel or Network Settings. It's important to ensure that the adapter itself isn't disabled by software in Device Manager.
To check, go to Control Panel → Network and Internet → Network and Sharing Center → Change adapter settingsHere you'll find the "Wireless Network Connection" icon. If it's grayed out and labeled "Disabled," right-click it and select "Enable." If there's no icon at all, the system isn't detecting the hardware, indicating a driver issue.
It is also important to check the protocol properties TCP/IPv4Double-clicking the adapter will open the status window, where you should click "Properties." In the list of components, select "Internet Protocol Version 4 (TCP/IPv4)" and ensure that the "Obtain IP Address Automatically" and "DNS" options are checked. Manual settings may conflict with the router's settings.

☑️ Connection diagnostics
Installing and updating drivers
The lack of a driver is the most common reason why Lenovo B560 doesn't see the Wi-Fi network. In the Device Manager (opened via devmgmt.msc) in the "Network adapters" section there should be a device with the name Wireless, Wi-Fi or the name of the chip (for example, Atheros, Realtek, Broadcom). If the name says "Unknown device" with a yellow exclamation mark, the driver is missing.
The B560 model typically uses different modules depending on the batch. Therefore, it's not recommended to blindly download the first driver you come across. It's best to use the automatic driver detection tool on the Lenovo support website or check the laptop's documentation for the exact adapter model. A system restart is required after installing the driver.
Sometimes a new driver version doesn't work reliably with older hardware. In this case, roll back the driver to the previous version or install a compatible Windows 7 driver in compatibility mode if you're using Windows 10. This often helps when standard update tools fail to find suitable software.
⚠️ Attention: When installing drivers manually, always uninstall the previous version through Add or Remove Programs to avoid library file conflicts.
Please pay attention to the bitness of your system. A driver for 32-bit Windows will not work on a 64-bit version, and vice versa. Check the system type in "My Computer" properties before downloading files.
What to do if the driver is not installed?
If the installation is interrupted by an error, try running the installer as administrator. Temporarily disabling your antivirus and firewall may also help. In rare cases, you may need to manually specify the path to the INF file through Device Manager by selecting "Update Driver" -> "Choose from List" -> "Have Disk."
WLAN AutoConfig and Zero Configuration Service
In Windows operating systems, special services are responsible for searching for and connecting to wireless networks. If this service is stopped, the Wi-Fi icon in the system tray may display a red cross or the message "No connections available." For Windows 7 and earlier, this service is critical. Wireless Zero Configuration, and for Windows Vista, 7, 8, 10 - WLAN AutoConfig.
You can check the service status by clicking Win + R and entering the command services.mscIn the list that opens, find "WLAN AutoConfig." Double-click it to open its properties. Make sure "Startup type" is set to "Automatic" and the service is running. If it is stopped, click "Start."
Service conflicts are rare, but possible if third-party Wi-Fi management software is installed on your computer. In this case, you may need to disable one service for the other to function correctly. However, for a standard configuration Lenovo B560 the standard Windows service is sufficient.
If the service fails to start and returns an error, check its dependencies. The "Dependencies" tab of the service properties lists the components it requires. Often, the problem lies in a disabled Connection Manager service or system files.
Diagnostics via command line
For advanced users and when the graphical interface doesn't provide answers, there's a powerful tool: the command line. Running it as an administrator allows you to obtain detailed information about the wireless module's status. netsh wlan show interfaces will show the connection status, network name and signal strength.
If the module returns an error or is unresponsive, you can try resetting the TCP/IP stack and network settings. This often helps after virus attacks or network protocol failures. The reset command requires administrator privileges and a reboot.
netsh int ip reset reset.log
netsh winsock reset
After executing these commands, the system will reset to factory network settings. This is a safe procedure that doesn't delete personal files, but may require you to re-enter your Wi-Fi network passwords.
Common problems and their solutions
Despite following the instructions, users Lenovo B560 You may encounter specific problems. For example, your laptop may see the network but fail to connect, displaying the message "Unable to connect." This is often resolved by deleting the network profile from the list of known networks and re-entering the password.
Another common problem is slow speeds or constant connection drops. This can be caused by outdated router security standards. For stable operation on the B560, it is recommended to use the WPA2-PSK (AES) encryption mode., as older WEP modes or mixed WPA/WPA2 modes may cause driver instability.
It's also worth checking the power settings of the adapter itself. In Device Manager, under the Wi-Fi module properties, on the "Power Management" tab, there may be a checkbox next to "Allow the computer to turn off this device to save power." Unchecking this box will prevent Wi-Fi from disconnecting spontaneously when idle.
Why doesn't the Fn+F5 button work?
Most often, the problem stems from a missing keyboard driver or the Lenovo Hotkey Features Integration utility. Without this software, the operating system cannot recognize the function key signals. Install the Chipset and Hotkey drivers from the official website.
Can I use an external USB Wi-Fi adapter?
Yes, if the built-in module is physically damaged, an external USB adapter is a great solution. Windows 10 and 11 often install drivers automatically, but Windows 7 may require a driver disc.
How do I know which Wi-Fi driver is needed for the B560?
The most accurate way is to look at the hardware ID in Device Manager. Right-click the unknown device → Properties → Details → Hardware ID. The VEN and DEV codes can be used to accurately determine the chip manufacturer.
Does a dead BIOS battery affect Wi-Fi?
Although extremely rare, a dead CMOS battery can reset BIOS settings, including the state of integrated devices. If the time and settings are reset every time you boot, replace the CR2032 battery on the motherboard.
