Laptop Lenovo B590 — is a reliable workhorse, still actively used in many offices and homes. However, users often encounter a situation where, after reinstalling the operating system or a sudden failure, the wireless network stops working. The absence of the Wi-Fi icon in the system tray or a red cross on the connection icon can be caused by trivial issues that are easy to fix.
In this article, we'll detail all possible ways to activate the wireless module on this model. We'll cover both hardware switches and software settings in Windows. Understanding these nuances will help you quickly restore internet access without calling a service center.
Before attempting complex driver manipulation, it's worth checking the basic settings. Often, the problem stems from an accidentally pressed key combination or a disabled module in the BIOS. Carefully following the instructions below will allow you to consistently rule out all possible causes of the problem.
Hardware switches and hotkeys
The first thing you need to check on your laptop is Lenovo B590, is the physical state of the switches. Unlike modern ultrabooks, where control is often entirely software, this model may have hardware limiters. A mechanical slider is sometimes located on the side of the case (usually the front or side) that disconnects the power supply to the Wi-Fi module.
If there's no mechanical switch or it's set to the "On" position, you should check the keyboard. The function row keys have special icons. To activate wireless networks on Lenovo devices, traditionally use the following combination: Fn + F5Pressing this combination brings up the wireless device management menu.
In the window that appears Lenovo Wireless Device Settings You'll see the status of the Bluetooth and Wireless LAN modules. If the Wi-Fi indicator is red or says "Off," you'll need to press the corresponding button in the interface or use the hotkey again to switch the status to "On."
⚠️ Attention: If you press Fn + F5 If nothing happens, your laptop may not have the proprietary Lenovo utilities responsible for processing the function keys installed. In this case, the operating system simply doesn't understand the command.
Setting up a wireless adapter in Windows
After checking the keyboard, we move on to the operating system software. In Windows 10 and 11, network connection management is located in a separate menu, but the classic Control Panel interface remains accessible. To access the adapter settings, click Win + R and enter the command ncpa.cpl.
In the window that opens, locate the "Wireless Network Connection" icon. If it's grayed out and labeled "Disabled," right-click it and select "Enable." This activates the driver at the operating system level.
It's also worth checking your power settings, as Windows may automatically turn off the device to save power. In Device Manager, find your adapter, go to Properties, the "Power Management" tab, and uncheck "Allow the computer to turn off this device."

Installing and updating Wi-Fi drivers
The most common reason for the lack of Wi-Fi on Lenovo B590 The driver is missing or not working correctly. This often happens after a clean installation of Windows. If you see "Unknown device" with a yellow exclamation point in Device Manager, the driver is definitely not installed.
For this model, it's important to select the driver specifically for your wireless card chipset. B590 laptops may have modules from different manufacturers: Realtek, Atheros or BroadcomInstalling the Realtek driver on an Atheros card will not produce the desired result.
Download software only from the official Lenovo support website or using verified driver archives. After downloading the archive, unzip it and run the installer. setup.exe on behalf of the administrator.
| Card manufacturer | Device type | Refresh rate | Stability |
|---|---|---|---|
| Realtek | RTL8723AE | Rarely | High |
| Atheros | AR9485 | Average | Average |
| Broadcom | BCM4313 | Rarely | High |
| Intel | Centrino | Often | Very high |
☑️ Checking drivers
Diagnostics via Device Manager
Device Manager is the primary tool for diagnosing hardware issues. To open it, right-click the Start button and select Device Manager. It displays the current status of all components on your computer. Lenovo.
Pay attention to the "Network Adapters" section. If your Wi-Fi module is listed there but has an error code (such as code 10 or 43), this indicates a resource conflict or hardware failure. In this case, remove the device from the list and click "Update hardware configuration" to have the system attempt to initialize it again.
If the module doesn't appear in any of the sections, including "Other Devices," this may indicate that the motherboard isn't detecting the wireless card. In rare cases, a static discharge test can help: turn off the laptop, disconnect the battery (if removable) and power supply, then hold down the power button for 15-20 seconds.
What to do if the device is not detected?
If your laptop stops detecting the Wi-Fi module after cleaning or dropping it, the antenna or module itself in the Mini-PCIe slot may have become loose. Disassembly and reconnection are required.
BIOS and UEFI settings
Sometimes the wireless interface can be disabled at the BIOS level. This is rare, but it's possible, especially if the laptop has been repaired or the settings have been reset. To enter the BIOS on the Lenovo B590, you typically use the key F2 or a special button Novo Button with the laptop turned off.
In the BIOS menu you need to go to the tab Configuration or AdvancedLook for an item containing the words Wireless LAN, WLAN Device or Onboard WLAN. Make sure the value is set to EnabledIf it's worth it Disabled, change the parameter and save the settings with the key F10.
It's also worth checking the boot mode and operating system compatibility in the BIOS, although this affects Windows booting more than the operation of specific devices. However, in some cases, switching the mode CSM or UEFI may affect peripheral initialization.
⚠️ Caution: Use caution when changing BIOS settings. Incorrect settings may cause system instability. Write down the original values before making changes.
Solving common connection problems
Even if the adapter is enabled, you may still experience issues connecting to a specific network. This is often due to incompatible encryption standards or frequencies. Laptop Lenovo B590 may not support the standard Wi-Fi 6 (802.11ax), working primarily with 802.11 b/g/n.
If your laptop sees networks but won't connect, try forgetting the network in Windows settings and re-entering the password. Resetting network settings via the command line also helps. Open Terminal as administrator and enter the command to reset the TCP/IP stack.
netsh int ip resetnetsh winsock reset
ipconfig /flushdns
After running these commands, be sure to restart your computer. This will flush the DNS cache and reset network sockets, which often resolves connection freezes.
