It is important to understand that hot keys These commands only work if the chipset drivers and management utilities are installed correctly. Without them, the operating system won't recognize the special commands reserved by the laptop manufacturer.
Installing and updating wireless adapter drivers
The most common cause of connection problems on Lenovo B590 is the absence or incorrect operation of drivers. This laptop model could have been equipped with modules from different manufacturers, such as Atheros, Realtek or BroadcomTherefore, there is no universal driver "for everyone," and you need to select software specifically for your device.
First, you need to determine which adapter is installed on your system. You can do this through Device Manager. Right-click "My Computer" (or "This PC"), select "Properties," then go to "Device Manager." You'll see the name of your device in the "Network Adapters" list.
If you see "Unknown device" with a yellow exclamation point instead of the adapter's name, the driver isn't installed. In this case, you'll need to download the installation file from the official Lenovo support website or the chip manufacturer's website using another device with internet access and transfer it to your laptop via USB.
How to determine the adapter vendor without drivers?
If the device is marked as unknown in Device Manager, open its properties, go to the "Details" tab, and select "Hardware IDs." Copy the top line (e.g., VEN_168C&DEV_0032) and enter it into the search engine at pci-ids.ucw.cz or your favorite search engine. The first four characters after VEN_ indicate the manufacturer (168C - Atheros).
When installing drivers, be sure to follow the manufacturer's recommended order. Chipset drivers are installed first, followed by power management drivers, and only then by network adapter drivers. Failure to follow this order may result in the adapter installing but not working properly or constantly disconnecting.
⚠️ Please note: Support website interfaces and driver versions may be updated. Always check your operating system version (Windows 7, 8, 10) when downloading files, as drivers for different Windows versions are not always compatible.
Configuring network settings in Windows
After successfully installing the drivers, the next step is to configure the network settings in the operating system itself. Windows may have its own priorities and restrictions that block the connection. First, check that the adapter is enabled in the list of network connections.
To do this, click Win + R, enter the command ncpa.cpl and press Enter. In the window that opens, find the "Wireless Network" connection. If it's grayed out and has a "Disabled" status, right-click it and select "Enable."
Next, you need to ensure that your laptop obtains an IP address automatically if your router is configured in standard mode. Double-click the wireless connection icon, select "Internet Protocol Version 4 (TCP/IPv4)," and click "Properties." Make sure "Obtain an IP address automatically" and "Obtain DNS server address automatically" are checked.
| Parameter | Recommended value | Description |
|---|---|---|
| IP address | Automatically | Allows the router to issue an address |
| DNS server | Automatically | The provider's servers are used |
| Gateway | Automatically | Internet access address |
| WINS | Not used | Legacy Name Protocol |
In some cases, especially in corporate networks or when using specific provider settings, it may be necessary to assign static addresses. However, for home use, Lenovo B590 Automatic tuning is the most reliable and simple option.
☑️ Check network settings
Diagnostics and management of Windows services
The Windows operating system manages network connections through special background processes called services. If the service responsible for wireless networking is stopped or disabled, connecting will be impossible even with properly functioning drivers. This is a common issue after system optimization or virus attacks.
To check the status of services, click Win + R, enter services.msc and press Enter. Find the "WLAN AutoConfig" service in the list. Double-click it and ensure the startup type is set to "Automatic" and the service is running.
If the service is stopped, click the "Start" button. It's also worth checking the "Remote Access Connection Manager" service. Although it's more often used for VPN and PPPoE connections, its incorrect operation can affect the overall network stack.
- 🛠 Open the services console with the command
services.msc. - 📡 Find "WLAN AutoConfig Service" in the list.
- ▶ Start the service and set the startup type to "Automatic".
- 🔄 Restart your laptop to apply the changes.
The changes will take effect after a system reboot. If the service disables itself again, this may indicate a software conflict or malware blocking network activity.
Troubleshooting common connection errors and issues
Even with proper configuration, users Lenovo B590 You may experience intermittent connection drops or an inability to connect to certain networks. One common cause is power saving settings. Windows may attempt to conserve power by powering down the adapter, which can cause connection drops.
