Model Lenovo B570e — is a classic example of a budget laptop, still widely used in many offices and homes. Despite its age, its functionality is sufficient for basic tasks, but users often encounter difficulties when trying to establish a wireless connection. The issue can lie with either the hardware switch or the software.
In this article, we'll take a detailed look at all possible ways to activate the wireless module. We'll cover everything from physical buttons to the intricacies of operating system settings. WindowsYou'll learn why the indicator might not light and what to do if the drivers stop responding. The main thing is not to panic if the network doesn't connect the first time, as the steps are fairly standard.
It's worth noting that a lack of Wi-Fi could be caused by a simple BIOS lockup or a faulty module itself. However, in 90% of cases, the issue can be resolved by using the correct key combination or reinstalling the driver. Let's go through each step step by step so you can diagnose and fix the problem yourself.
Finding physical switches and indicators
The first thing you need to do to begin diagnostics is a visual inspection of the laptop case. On the model B570e Manufacturers often included mechanical switches or software buttons to control wireless interfaces. Carefully inspect the front edge of the case, as well as the area above the keyboard.
If there is no obvious slider with the inscription on the case Wireless or an image of an antenna, pay attention to the keyboard. Often, the Wi-Fi function is combined with one of the function keys. F1-F12On Lenovo laptops, this is usually the key F5 or F7, on which is depicted the symbol of a radiating antenna or an airplane.
⚠️ Note: On some B570e models, the mechanical switch may be hidden under the removable battery or located on the side near the Ethernet port. Carefully examine all edges of the device with the lights off to spot the markings.
To activate a function, you often need to use a keyboard shortcut. Hold down the key Fn, located in the bottom row on the left, and without releasing it, press the corresponding function key. The screen may flash, or a graphical device management menu will appear, where you need to select WLAN.
Using Lenovo Keyboard Shortcuts and Menus
Once you've found the right key, it's important to press it correctly. In the operating system Windows A special utility from the manufacturer is often responsible for processing these combinations. If the keyboard drivers are not installed or are damaged, pressing Fn + F5 may not provide any visual response.
In some firmware versions, when you press a combination, a menu appears on the screen Lenovo Wireless Device SettingsIn this window, you can toggle the status of the Bluetooth and Wi-Fi modules independently. Make sure the status is set to On or Enabled.
- 🔹 Click
Fn + Escto lock or unlock the function keys (Fn Lock mode). - 🔹 Check if Airplane mode is enabled via the system tray.
- 🔹 Try pressing the key combination several times with an interval of 2-3 seconds.
If the default combinations don't work, hotkey support may be disabled in the BIOS. You should also check if the utilities are installed. Lenovo Energy Management or Hotkey Features IntegrationWithout them, the operating system may simply not understand what you're asking it to do by turning on the wireless adapter.
☑️ Checking keyboard shortcuts
Configuring the adapter in the Windows operating system
If the physical buttons are working but there's no internet, the problem may be a software issue with the adapter. In Windows 7, 8, or 10, network connections are managed through the Control Panel. Click Win + R and enter the command ncpa.cpl for quick access to the list of adapters.
In the window that opens, find the icon Wireless network connectionIf it's grayed out and labeled "Disabled," right-click it and select "Enable." The system will begin searching for available networks, which may take a few seconds.
In newer versions of Windows, this control is often moved to the system settings. Go to the Start menu, select Settings (the gear icon), and open Network & Internet. Here you can quickly activate the Wi-Fi slider and run troubleshooting.
| Status in the dispatcher | Indicator on the body | Action |
|---|---|---|
| The device is disabled | It doesn't burn. | Right-click -> Enable |
| The device is working. | On/Blinking | Search for networks in the tray |
| No device | It doesn't burn. | Check drivers |
| Error (code 10/43) | It doesn't burn. | Reinstall the driver |
⚠️ Warning: If you see a device with a yellow exclamation point or error code 10, this indicates a resource conflict or driver failure. Simply turning it on won't help; a software reinstallation is required.
Installing and updating Wi-Fi drivers
The most common reason for the lack of Wi-Fi on Lenovo B570e — missing or incorrect driver operation. The model was equipped with modules from different manufacturers: Atheros, Realtek or BroadcomTherefore, there is no universal driver "for everyone"; you need to select a specific version.
First, find out the hardware ID. Open Device Manager (command devmgmt.msc), find the "Network adapters" or "Other devices" section. If you see an unknown device there, right-click it, select "Properties" -> "Details" tab -> "Instance ID" or "Hardware ID."
Copy the top line of code (eg. PCI\VEN_168C&DEV_002B) and enter it into a search engine. This will help you find the exact driver for your chipset. You can also use the program DriverPack Solution or the official Lenovo support website, specifying the exact laptop model.
Where can I download a driver if my laptop doesn't have internet access?
If your laptop doesn't have network access, download the driver on another computer or smartphone. Save the installation file to a flash drive or transfer it via USB cable. Make sure the driver version matches your Windows bitness (x86 or x64).
After installing the driver, be sure to restart your computer. Only after restarting will the system fully initialize the new module and assign it the necessary resources. If the network icon appears after rebooting, but no networks are found, check the WLAN autoconfiguration service.
Diagnostics via Device Manager
A thorough diagnosis begins with the Device Manager. If the "Network Adapters" section is missing from the hardware list, or there's no mention of Wireless, 802.11 or Wi-Fi, then the system doesn't see the physical device. This could indicate a hardware failure or malfunction.
Try updating the hardware configuration. In the Device Manager menu, click "Action" -> "Update Hardware Configuration." The system will attempt to scan all buses again. If the module is healthy, it should appear in the list, possibly with a request to install drivers.
- 🔹 Check if the devices are hidden in the View -> Show hidden devices menu.
- 🔹 Remove the device (RMB -> Remove) and reboot to reinitialize.
- 🔹 Pay attention to the error codes in the device properties (Code 1, 10, 12, 43).
Manually selecting a driver from a list often helps. When updating a driver, select "Choose a driver from a list of available drivers on my computer." If there are multiple options in the list, try selecting a different one, even if the current one is marked as recommended. Older drivers sometimes perform more reliably than newer ones on this type of hardware.
Checking services and power parameters
A special service is responsible for the operation of wireless networks in Windows. Click Win + R, enter services.msc and find "WLAN AutoConfig" in the list. Make sure the startup type is set to "Automatic" and the service is running.
Another common issue is power saving. Windows may disable the Wi-Fi adapter to conserve battery power, but then fail to enable it correctly. Open the network adapter properties in Device Manager and go to the "Power Management" tab.
Uncheck "Allow the computer to turn off this device to save power." This will prevent the system from turning off the module in the background. After applying the settings, reboot and test the connection stability.
⚠️ Note: On Lenovo B570e laptops with a worn-out battery, the system may aggressively conserve power. If the laptop only runs on AC power, try removing the battery and running the device directly from the charger to check the stability of the Wi-Fi.
Troubleshooting BIOS and Hardware Issues
If software methods don't help, it's worth checking the BIOS. When turning on the laptop, press the F2 or Fn + F2Find the section in the menu Configuration or Advanced. Parameter Wireless LAN or Onboard WLAN Device must matter Enabled.
Sometimes the Wi-Fi module simply comes loose from the contact. In the model B570e To access it, you need to remove the back cover (usually just unscrewing one screw marked "WLAN"). The module is a small board with two antenna wires (black and white).
Carefully disconnect the antennas (they are removed by pushing upwards), remove the module from the slot, clean the contacts with an eraser, and reinsert it until it clicks into place. Then connect the antennas: the white one to the connector. Main (or 1), black to Aux (or 2). This often solves the problem of the device disappearing.
Frequently Asked Questions (FAQ)
Why doesn't the Fn+F5 key work on my Lenovo B570e?
Most likely, the Hotkey Features Integration drivers or the Lenovo Energy Management utility are not installed. Without them, the operating system won't process function key presses.
Is it possible to use an external Wi-Fi adapter if the built-in one is burned out?
Yes, that's a great solution. You can connect a USB Wi-Fi adapter. Windows 10 and 11 often find drivers for them automatically, or they come bundled. It's best to disable the built-in module in the BIOS to avoid conflicts.
How do I know which Wi-Fi module is installed in my B570e?
The best way is to look in Device Manager, under Properties -> Details -> Hardware IDs. You can use the first digits (VEN_XXXX) to identify the chipset manufacturer online.
Why does my laptop see my neighbors' networks but not mine?
The problem may be with the router channel. If the router is running on channel 12 or 13, and the Wi-Fi card driver is set to the US standard (which only allows channels 1-11), the network won't display. Try changing the channel in the router settings to 1, 6, or 11.
Should you update your Wi-Fi drivers automatically on Windows 10?
Not always. For older models like the B570e, automatic updates via Windows Update may install the incorrect universal driver. It's better to use a verified version from the official website or one that has worked reliably in the past.
