How to enable Wi-Fi on a Lenovo B590 laptop

Laptop Lenovo B590 — is a reliable workhorse, still found in many offices and homes. However, owners of this model often encounter situations where the wireless module suddenly stops responding to commands or simply fails to detect available networks. The problem can be rooted in a software glitch in the operating system or simply a disabled physical switch, the existence of which many forget.

Before panicking and taking your device to a service center, it's worth running a thorough diagnostic. In most cases, no signal This is related to power saving settings or a driver conflict, not a failure of the module itself. Understanding the connection architecture in this particular series will help you save time and money by restoring your laptop to full functionality in minutes.

In this article we will look at all possible activation methods. wireless adapter, from simple mechanical actions to complex reinstallations of system components. You'll learn to distinguish between software locks and hardware malfunctions, a key skill for any portable device user.

Checking hardware switches and hotkeys

The most common reason for the lack of internet on Lenovo B590 — This physically disables the module. Unlike modern Ultrabooks, this model is equipped with a separate mechanical slider that completely cuts off power to the Wi-Fi antenna. It's located on the front edge of the case, usually on the right side, next to the status indicators. Make sure this switch is set to the "ON" position. On or 1.

If the mechanical switch is active but the network is not working, you need to use the function keys. On the keyboard B590 The combination responsible for turning wireless interfaces on and off is Fn + F5Pressing this link brings up a device management menu on the screen, where you can individually activate Wi-Fi and Bluetooth.

⚠️ Note: In some BIOS versions, the function of the function keys may be inverted. If a simple combination doesn't work, try holding down the key Fn and press several times F5, holding the first one.

Users often forget that a special driver is required for hotkeys to work correctly. Lenovo Hotkey Features IntegrationWithout this software, pressing buttons won't change anything in the system. Check your Task Manager for the relevant processes or install the utility from the official support website.

Configuring settings in the Windows operating system

After confirming the physical health of the network adapter, you should move on to the software component. In Windows operating systems, network adapter management is centralized. To access the settings, click Win + R and enter the command ncpa.cplIn the window that opens, find "Wireless Network" and make sure it is not grayed out, indicating it is disabled.

If the adapter is shown as "Disabled," right-click it and select the appropriate menu item to activate it. Sometimes the system may block the device due to power settings. To eliminate this, go to the adapter's properties and click the Tune and go to the tab Power managementUncheck the box next to "Allow the computer to turn off this device to save power."

In Windows 10 and 11, you can also control this feature through the Action Center. Click the network connections icon in the system tray and check if Airplane Mode is enabled. This mode disables all radios, ignoring other settings.

Why does the adapter disappear from the list?

If your wireless adapter has completely disappeared from the list of network connections, this may indicate a problem with the WLAN AutoConfig service. Check its status in the Services section (services.msc) and ensure it is running and the startup type is set to "Automatic."

Installing and updating wireless module drivers

Lack of the correct driver is the second most common cause of Wi-Fi problems on Lenovo B590This model was released with various modifications of network cards from manufacturers. Atheros, Realtek or BroadcomThere is no universal driver, so it is necessary to accurately identify your hardware.

To determine the device model, open the Device Manager via the context menu of the Start button or by using the command devmgmt.mscFind the "Network Adapters" section. If you see a device with a yellow exclamation mark or an "Unknown Device" entry, right-click it, select "Properties," and then go to the "Details" tab. Select "Hardware IDs" from the drop-down list.

Copy the top line of the identifier (eg. PCI\VEN_168C&DEV_002B) and enter it into a search engine. This will help you find the exact chip model. Then, download the driver from the official Lenovo website, specifying your laptop model. B590 and your version of Windows.

When installing drivers, always use compatibility mode if you're installing software designed for an older version of Windows. This can sometimes help avoid installation errors on Windows 10 or 11.

Diagnostics via Device Manager

Device Manager is the primary tool for in-depth diagnostics. If your module appears in the list of network adapters but isn't working correctly, the system will typically assign it an error code. Double-clicking the device will open the status window, where the "Device Status" field will display the code, for example, Code 10 or Code 43.

Code 10 often indicates that the device cannot start. In this case, try completely uninstalling the driver from the system. To do this, select "Uninstall device" in the device's context menu and be sure to check "Delete the driver software for this device." After this, restart your laptop—the system will attempt to reinstall the driver.

Code 43 usually indicates a hardware failure reported by the device itself. A static discharge test may help. Turn off the laptop, unplug the charger, and remove the battery. Press and hold the power button for 30 seconds. Then replace the battery and try turning on the device.

⚠️ Attention: If after all manipulations the Device Manager displays "Unknown device" without a hardware ID, it is possible that the Wi-Fi module has physically moved away from the Mini-PCIe slot inside the case.

Using the Command Prompt to Reset the Network

Sometimes software glitches accumulate in Windows network settings, and a simple reboot doesn't help. In such cases, a complete reset of the network stacks via the command line is an effective method. This method is especially useful when the adapter is enabled and the drivers are installed, but connections to access points fail.

Run the command prompt as administrator. To do this, find cmd In the search box, right-click and select "Run as administrator." Enter the following command to reset the TCP/IP protocol:

netsh int ip reset

Then reset the Winsock settings, which are responsible for how applications interact with the network:

netsh winsock reset

After running these commands, be sure to reboot your computer. The system will recreate your network configurations from scratch, which often resolves hidden conflicts that may be interfering with your system. wireless connection.

Solving problems with BIOS and UEFI

Basic Input/Output System (BIOS) settings may block the wireless module at the hardware level. In laptops Lenovo B590 Entering the BIOS is done by pressing the key F2 or a special button Novo Button with the laptop turned off. You need to find the section related to hardware configuration, usually called Configuration or Advanced.

Look for the item inside the menu Wireless LAN or Onboard WLAN Device. Make sure the value is set to EnabledIf it's there Disabled, the operating system won't see the adapter, and no drivers will help. Also, check if the mode is enabled. OS Optimized Defaults, which sometimes changes the boot priorities and settings of devices.

If you're unsure of what you're doing, you can reset the BIOS to factory settings. This is usually done by pressing the F9 (Load Setup Defaults) inside the BIOS, after which you need to save the changes by pressing the key F10.

⚠️ Warning: Changing BIOS settings may affect system stability. Write down the original settings before changing them so you can revert back.

Frequently Asked Questions (FAQ)

Why is the Wi-Fi indicator orange instead of blue?
