How to enable Wi-Fi on a Lenovo B590 laptop and set up internet access

Laptop Lenovo B590 — is a reliable workhorse, still found in many offices and homes. However, given the age of the model, users often encounter difficulties when trying to connect to a wireless network. The problem can lie in the physical switch, which is easily touched, or in a software glitch in the drivers or operating system. Knowing where to look for the cause of a connection failure can save time and avoid unnecessary trips to a service center.

In this article, we'll cover all possible ways to activate the wireless module in detail. We'll cover both standard hotkey methods and more in-depth settings in the BIOS and Device Manager. An integrated approach This diagnostic tool will help you identify even hidden equipment faults. You'll learn to distinguish between software blockages and physical damage to the antenna.

It often happens that the indicator is lit, but no networks are found, or the system doesn't even detect the adapter. In such cases, it's necessary to check each level of the settings one by one, starting with simple steps and moving on to more complex ones. Windows 7, 8, or 10 may react differently to missing drivers, so it's important to understand the specifics of each version. Let's start with the most obvious, yet often overlooked, control.

Physical switches and hotkeys

The first thing a laptop owner needs to do is Lenovo B590, is to carefully inspect the device's casing. On the sides or front panel, there's often a mechanical slider that completely disables power to the wireless module. If it's in the "Off" position, no software settings will enable internet access. Make sure the switch is in the active position, usually to the right or with an antenna icon.

The second, more common control method is using the function keys on the keyboard. On the B590 model, the Wi-Fi activation is usually performed by a combination Fn + F5When you press this combination, the wireless device management menu should appear on the screen. If there is no response, the mode may be blocked. Fn, and then you just need to try to press F5The indicator on the key may flash or change color to indicate a status change.

⚠️ Important: If pressing the hotkey combination does not display the Lenovo Control Menu, this may mean that the Lenovo Energy Management utility is not installed. Without this software, the hotkeys will not work.

It's also possible that the keyboard is sticking or the cable is damaged, which is common on older laptops. In this case, use the on-screen control method via the Mobility Center. Right-click the battery icon or search for "Windows Mobility Center" in the Start menu. There's often a duplicate wireless button there, which may be active even if the buttons on the case aren't working.

Checking the adapter status in Windows

After checking the physical buttons, you need to move on to the software diagnostics. The operating system may be shutting down the device to save power or due to an error. Open the Network Control Panel by clicking Win + R and entering the command ncpa.cplIn the window that opens, find the "Wireless Network" icon. If it's gray and says "Disabled," right-click it and select "Enable."

In some cases, the adapter may be hidden or disabled in Device Manager. Right-click "My Computer," select "Properties," and then go to "Device Manager." Expand the "Network Adapters" branch. If you see a device with a yellow exclamation point or the text "Unknown Device," the problem is with the drivers. If the adapter isn't there at all, click "View" → "Show Hidden Devices."

It's important to pay attention to your power settings. Windows tends to disable the Wi-Fi module, considering it inactive. In Device Manager, double-click your adapter, go to the "Power Management" tab, and uncheck "Allow the computer to turn off this device to save power." This often resolves the issue of the network spontaneously disappearing.

Hidden devices in the device manager

If the adapter appears translucent, it was previously connected but is now inactive. Try removing it and clicking "Scan for hardware configuration" to force the system to attempt to initialize it again.

Installing and updating drivers

The most common reason for Wi-Fi not working on Lenovo B590 — missing or incorrectly functioning drivers. This model was often bundled with adapters from different manufacturers: Atheros, Broadcom, Realtek or IntelTo find out the exact model of your device, you can use the command devmgmt.msc and view the hardware properties in the "Details" tab by selecting "Hardware ID".

It's best to download drivers from the official Lenovo support website, specifying your exact laptop model. However, if your laptop's internet connection isn't working, you can download them on another device and transfer them via USB. Universal driver packages are also available, but proceed with caution, as they may contain unnecessary software. Always select the "Custom Installation" option during installation to avoid installing unnecessary toolbars.

After installing the driver, be sure to restart your computer. If the system prompts you to update the driver via Windows Update, accept the prompt, but be careful not to install an older version. Windows 10 can sometimes automatically replace a working driver with its own, less stable version. In this case, in the driver properties, select "Roll Back Driver" or "Update Driver" → "Choose from a list of available drivers on this computer."

Configuring wireless network settings

Once the adapter is enabled and the drivers are installed, you need to configure the connection settings correctly. Go to "Network and Sharing Center" and select "Change adapter settings." Right-click "Wireless Connection," select "Properties," then "Internet Protocol Version 4 (TCP/IPv4)." In most cases, the options for automatically obtaining an IP address and DNS server should be checked. However, if your ISP requires a static IP address, you'll need to enter these details manually.

Pay special attention to the network profile. When you first connect, Windows asks you about the network type: "Home," "Work Network," or "Public Network." For a home network, it's best to choose "Home," as it opens the necessary ports for file and printer sharing and ensures the appropriate level of security. If you choose "Public," some features may be blocked by your firewall.

For advanced users, configuration is available via the command line. Run cmd as administrator. Using the command netsh wlan show profiles You can view saved networks. If the network exists but won't connect, you can delete its profile with the command netsh wlan delete profile name="Network_Name" and reconnect by entering the password.

⚠️ Note: The network settings interface may differ depending on your Windows version (7, 8.1, 10, 11). In Windows 10, many features have been moved to the "Settings" app (the gear icon in the Start menu) under "Network & Internet."

Diagnostics via BIOS and UEFI

If software methods don't help, the wireless module may be disabled at the BIOS level. To enter the BIOS, Lenovo B590 You need to actively press the key when turning on the laptop F2 or a special button Novo Button (a small hole or button next to the power button). In the BIOS menu, go to the "Configuration" or "Advanced" tab.

Find the item related to wireless devices. It may be called Wireless LAN, Onboard WLAN or Wireless Device. Make sure there is a value next to it. EnabledIf it's there Disabled, change to enabled, save settings with the key F10 and exit. Also check if the mode is enabled Airplane Mode in the BIOS settings, if such an item is present.

In rare cases, resetting the BIOS settings to factory defaults can help. To do this, select "Load Setup Defaults" or "Load Optimized Defaults" in the BIOS menu. This will return all system settings to their original state, which can correct hardware configuration errors caused by power surges or system failures.

Hardware problems and maintenance

Laptop Lenovo B590 The laptop is no longer new, and physical problems can develop over time. One common cause is the antenna wires coming loose from the Wi-Fi module. The antennas (black and white wires) are attached to a small module inside the case, usually under the keyboard or in a compartment on the bottom. If the laptop has been dropped or disassembled, the connection may be broken, resulting in a very weak signal or no signal at all.

It's also worth checking the integrity of the module itself. It's a small Mini PCI-E card. The contacts on it can become corroded. Carefully cleaning the contacts with an eraser and firmly reinserting the module into the slot often restores functionality. When installing the module, it's important to insert it at a 30-45 degree angle and engage the latches.

If all else fails, you can use an external USB Wi-Fi adapter. This is a simple device, similar to a flash drive, that plugs into a USB port. It takes over the functions of the built-in module. This is an excellent temporary or even permanent solution if the built-in adapter burns out or fails. Modern USB adapters support the standard. 802.11ac and work faster than older built-in cards.

What should I do if my laptop sees networks but doesn't connect?

If the network list is available but you can't connect, the problem is most likely with your router's password or security settings. Try forgetting the network and re-entering the password. Also, check if your router is using MAC address filtering. Make sure your laptop's date and time are set correctly—time desynchronization can block a secure connection.

Can Lenovo B590 be used with Windows 10/11?

Yes, the B590 model is fully capable of running Windows 10, and with an SSD and sufficient RAM (4-8 GB), it can also run Windows 11 (by bypassing limitations). However, drivers for older Wi-Fi modules may only be available for Windows 7 or 8. In this case, you can try installing the driver in compatibility mode or find a universal driver from the chip manufacturer.

How can I find out what Wi-Fi module I have without opening it?

Click Win + R, enter devmgmt.mscIn Device Manager, expand "Network Adapters." It will show a name, such as "Atheros AR9485" or "Broadcom BCM4313." If it says "Unknown Device," right-click and select "Properties" → "Details" → "Hardware IDs." Copy the top line (e.g. PCI\VEN_168C&DEV_0032) and enter it into your browser search - this will show the exact model.
