Laptop Lenovo IdeaPad B590 — is a reliable device that is still actively used in many offices and homes. However, users often encounter situations where the wireless module suddenly stops responding or is initially inactive. Turning on WiFi On this model, this can be done in several ways, depending on the state of the operating system and the BIOS version.
Before delving into software settings, it's important to rule out trivial mechanical causes for the lack of signal. In older models, such as the B590, there were often physical switches or key combinations that blocked radio emissions. If you've just reinstalled Windows or updated the system, the problem may be due to the lack of correct software for the network adapter.
In this guide, we'll cover all possible methods for activating a wireless network: from testing hardware buttons to manually installing drivers from the manufacturer's website. You'll learn how to diagnose the problem if standard methods fail, and which hidden BIOS settings may affect the module's operation. It is critical to check the physical slider on the case first, as it is often the one that blocks software activation.
Finding the physical switch and hotkeys
The very first step that an owner needs to take is Lenovo B590 — this is a careful inspection of the device's casing. Unlike modern Ultrabooks, where network management is entirely software-based, this series often features a mechanical switch. It's usually located on the front edge of the laptop, close to one corner, and has a distinctive antenna-shaped marking.
If you don't find a moving slider, the next step is to check the function keys on the keyboard. To activate the wireless module in the series IdeaPad Traditionally, a key combination is used. You need to find the key with an image of an antenna or an airplane on the F1-F12 row.
- 🔍 Carefully inspect the front and side edges of the case for the sliding switch.
- ⌨️ Find the key with the WiFi symbol (often F5 or F7) and press it together with Fn.
- 👀 Pay attention to the indicators: if the device is turned on successfully, the corresponding LED should light up.
Users often forget that for a combination to work, they must first hold down a key. Fn, located in the lower left corner of the keyboard. Only then should you press the function key once. If the indicators flash or change color, the power-on command has been sent. radio module was sent successfully.
⚠️ Note: If a crossed-out antenna or airplane icon appears on the screen when you press the key combination, this means you've put your laptop into Airplane Mode, completely disabling all wireless connections. Press the combination again to unlock it.
Software activation via the operating system
If physical methods fail, it is necessary to switch to software management of network interfaces. In operating systems of the family Windows (7, 8, 10) There are native tools for monitoring network connections. Sometimes the adapter may simply be disabled in the software environment.
To access settings in Windows 7 and earlier, click the Start button and select Control Panel. Next, go to Network and Internet, and then select Network and Sharing Center. On the left side of the window, find the link Changing adapter settings.
The window that opens will display all available network connections. Look for the icon labeled "Wireless Network Connection." If the icon is gray and labeled "Disabled," right-click it and select "Enable." The system will begin searching for available networks.
In more modern OS versions, such as Windows 10, the process is simplified. Simply click the network icon in the system tray (near the clock) and ensure the "Wi-Fi" tile is highlighted blue. If the tile is gray, click it to activate it. It's also worth checking to see if power saving mode is enabled, which could disable the adapter.
- 💻 Open Network and Sharing Center through Control Panel or System Settings.
- 🖱️ Find your wireless adapter in the list of connections.
- 🚀 Right-click and select "Enable" or "Connect."
☑️ Checking the adapter status
Installing and updating wireless network drivers
The most common reason for WiFi not working on Lenovo B590 After reinstalling Windows, there is a lack of drivers. Without special software, the operating system does not know how to interact with the installed network controllerIn the Device Manager, such equipment is usually marked with a yellow exclamation mark.
To resolve this issue, you'll need to find the exact model of your wireless adapter. Since your laptop isn't connected to the internet, you'll need to download the drivers on another device and transfer them via a USB drive or use your smartphone as a USB modem. Official drivers are best found on the Lenovo support website by entering your device's serial number.
The installation process looks like this: the downloaded file (usually has the extension .exe) must be run as administrator. Follow the installer instructions, agreeing to the license terms. After installation is complete, be sure to restart your computer for the changes to take effect.
| Component | Driver type | Installation sign | Need to reboot |
|---|---|---|---|
| Wireless LAN | Adapter driver | The network appears in the list | Yes |
| Bluetooth | Module driver | Peripheral work | Desirable |
| Energy Management | Lenovo Utility | Fn key operation | Yes |
| Chipset | Chipset driver | System stability | Yes |
⚠️ Note: Manufacturers' website interfaces and file structures may vary. If you can't find the driver by laptop model, try searching by hardware ID in Device Manager.
Setting up BIOS and UEFI interface
Sometimes software settings can be locked at the Basic Input Output System level. BIOSThis happens rarely, but if you reset the BIOS settings or performed hardware manipulation, the WiFi module may have been forcibly disabled. To enter the BIOS, Lenovo B590 the key is usually used F2 or a special button Novo Button next to the power connector.
Once you enter the navigation menu, use the arrows to go to the tab Configuration or Advanced. Find the item related to wireless technologies. It may be called Wireless LAN, Onboard WLAN or WiFi Controller. Make sure that the value opposite this item is Enabled.
If the value is set to Disabled, change it by pressing the key Enter or using the value change keys. After making changes, be sure to save the settings. To do this, go to the tab Exit and select the item Exit Saving Changes or just press the key F10 and confirm the action.
- 🔌 Turn off your laptop and press the Novo button or the F2 key when turning it on.
- ⚙️ Go to the Configuration section and find the Wireless LAN option.
- ✅ Set the value to Enabled and save changes before exiting.
Diagnosis and troubleshooting of common errors
Even after completing all the above steps, specific errors may still occur. For example, the system may report "Windows could not configure this connection" or the adapter may repeatedly disconnect. Often, the problem lies in the power settings, where the system attempts to conserve battery life by disabling the module.
To prevent the system from turning off the adapter, open Device Manager, find your wireless adapter in the Network Adapters list, right-click it, select Properties, and go to the Power Management tab. Uncheck "Allow the computer to turn off this device to save power."
Another common issue is a service conflict in Windows. Make sure the "WLAN AutoConfig" service is running and in automatic mode. To check, click Win + R, enter services.msc and find the required service in the list.
If all else fails, try resetting your network settings. In a command prompt running as administrator, you can run commands to reset the TCP/IP stack and DNS cache. This often helps resolve software glitches that have accumulated over time.

What should I do if the driver is installed but the adapter does not appear?
This may indicate a hardware failure of the module or its deactivation at the BIOS level. Try completely powering off the laptop: remove the battery (if it's removable), unplug the charger, and hold the power button for 30 seconds. Then reassemble everything and check the result.
Can I use an external USB WiFi adapter?
Yes, if it's a built-in module Lenovo B590 If your laptop is broken, you can buy an external USB adapter. It will be automatically detected by the system as a new network device, and you'll also need to install a driver for it, but this will save you from disassembling the laptop.
Why does the laptop see 2.4 GHz networks, but not 5 GHz?
Model B590 The router was equipped with different Wi-Fi modules. Older standards (802.11 b/g/n) only operate in the 2.4 GHz band. If your router only broadcasts the network at 5 GHz, the old adapter simply won't detect it. Check your module's specifications in Device Manager.
