Laptops of the series Lenovo B590 Wireless networks are still popular due to their reliability, but sometimes users encounter difficulties when trying to connect to a wireless network. A situation where the connection indicator doesn't light or the system reports no available connections often causes panic, but in most cases, the problem can be resolved using software or simply checking the physical switches.
Before embarking on complex diagnostics, it's important to understand that the wireless modules in this model can be controlled in several ways. These include hardware buttons on the case, keyboard function keys, and operating system settings. It's important to check each of these levels sequentially to rule out basic errors.
In this article, we will examine in detail all the possible reasons for the lack of connection on Lenovo IdeaPad B590We'll cover mechanical locks, installing the necessary drivers for Broadcom or Atheros chipsets, and methods for resolving software conflicts in Windows. The right approach will quickly get your laptop back online.
Checking hardware switches and indicators
The most common reason why Wi-Fi doesn't work on Lenovo laptops is a simple physical blockage of the module. B590 There may be a dedicated slide switch that completely shuts off the wireless adapter's power. Its location varies depending on the specific case model, but it's most often located on the front edge or side.
If there is no slide switch, control is via the keyboard. You need to find the key with the image of an antenna or airplane. On models Lenovo B590 it's usually a combination F5 or F7, which must be pressed simultaneously with the key FnPressing this combination sends a signal to the controller to turn the radio module on or off.
⚠️ Note: When switching wireless device modes, an OSD (On-Screen Display) pop-up window may appear on the screen. If it does not appear, the Lenovo management utilities or the ACPI driver may not be installed.
Pay attention to the indicator lights. An LED near the power button or on the touchpad should light up, indicating wireless connectivity. It typically glows green or blue when the connection is active and blinks or glows orange when disconnected. If the light doesn't glow when the switch is on, this could indicate a faulty module or missing drivers.
Installing and updating wireless adapter drivers
If the physical switches have been checked but the network still doesn't appear, it's likely that the operating system is missing the correct drivers. Laptop Lenovo B590 could be equipped with modules from different manufacturers, such as Broadcom, Atheros, or Realtek. For proper operation, you must install the driver specifically for your device.
You can determine the exact adapter model using Device Manager. Right-click "My Computer," select "Manage," and then go to "Device Manager." In the "Network Adapters" list, look for entries with the words "Wireless," "802.11," or brand names. If you see a device with a yellow exclamation point or "Unknown Device," a driver is definitely required.
Please download software exclusively from the official Lenovo support website. Enter your model number. B590 In the search bar, select your operating system version (Windows 7, 8, or 10) and find the "Network" section. Select the driver corresponding to your adapter and install it following the wizard's instructions.
What to do if there is no official driver for Windows 10?
Drivers for Windows 8 often work reliably on Windows 10. Try downloading the Win 8 version, running the installation in compatibility mode (right-click the installer -> Properties -> Compatibility), and select Windows 8.
After installation, be sure to restart your laptop. A restart is necessary for the operating system to properly initialize the new settings. communication protocol and registered the network adapter in the system.
Setting up a wireless connection in Windows
After successfully installing the drivers, you need to make sure the wireless connection is enabled in the operating system settings.

Here you can find options like Roaming Aggressiveness or Wireless Mode. Make sure the operating mode is set to 802.11 b/g/n or higher to ensure compatibility with modern routers.
☑️ Check network settings
Diagnostics via Device Manager
Device Manager is the primary tool for identifying hardware and software issues. If your wireless adapter appears with a yellow triangle in the hardware list, double-click it. The "Device Status" field will display an error code. Codes 10 or 43 often indicate a resource conflict or a malfunction within the module itself.
Try resetting the configuration. In the device properties window, go to the "Driver" tab and click "Roll Back Driver" if it's enabled. If not, select "Uninstall device," check "Delete the driver software for this device" (if enabled), and confirm the action. Then, in the Device Manager menu, select "Action → Scan for hardware changes."
It's also worth checking your power settings. In the "Power Management" tab of the adapter properties, uncheck "Allow the computer to turn off this device to save power." This will prevent the Wi-Fi module from disconnecting when the laptop goes into sleep mode.
| Error code | Description of the problem | A probable solution |
|---|---|---|
| Code 10 | The device cannot start | Reinstalling the driver, checking the switches |
| Code 28 | Drivers not installed | Installing software from the official Lenovo website |
| Code 43 | Windows has stopped the device | Relieving static voltage, replacing the module |
| Code 12 | Not enough resources | Disabling unused ports in BIOS |
Checking services and system settings
A specialized service is responsible for wireless networking in Windows. If it's disabled or not working correctly, you won't be able to turn on Wi-Fi even with a working driver. Press the combination Win + R, enter the command services.msc and press Enter.
In the list that opens, find the service WLAN AutoConfigDouble-click it. The startup type should be set to "Available" and the status to "Running." If the service is stopped, click the "Start" button.
⚠️ Warning: Changing system service settings may impact the stability of other network functions. Do not disable services whose purpose you do not understand.
It's also worth checking your firewall and antivirus settings. Sometimes third-party software blocks new connections. Try temporarily disabling your antivirus and checking for network availability. If the problem resolves, add your network environment to the exceptions.
Solving problems with BIOS and UEFI
In rare cases, the Wi-Fi module may be disabled at the BIOS level. This often happens after resetting the motherboard or updating the firmware. To check, enter the BIOS by pressing the [key] F2 or F1 when booting the laptop Lenovo B590.

Frequently Asked Questions (FAQ)
Why is the Wi-Fi indicator orange but no networks are found?
An orange indicator usually means the module is turned on but not connected to a network, or the signal is very weak. However, if no networks appear in the list at all, check whether the WLAN AutoConfig service is disabled or whether Airplane Mode is enabled. There may also be a mismatch between the router's security standards and the adapter's settings.
Is it possible to use an external USB Wi-Fi adapter if the built-in one doesn't work?
Yes, this is a great temporary or permanent solution. The external adapter is independent of the internal switches and the state of the built-in module. Simply plug it into a USB port, install the driver (often installed automatically in Windows 10/11), and you'll have a stable internet connection.
How do I know which driver I need for my B590?
The best way is to look at the hardware ID in Device Manager. Right-click the unknown device -> Properties -> Details -> Hardware ID. Copy the top line and enter it into a search engine. You can also use hardware scanners such as AIDA64 or HWiNFO.
