How to Enable Wi-Fi on a Lenovo B50-10 Laptop: All Methods (2014–2016)

Laptop Lenovo B50-10 — a budget model produced between 2014 and 2016, it's still used for office tasks, studying, and watching videos. However, owners often encounter a problem: Wi-Fi suddenly stops working, and the wireless network indicator stays off. The causes can range from accidental key presses to driver failures or hardware malfunctions.

In this article we will look at all possible ways to turn on Wi-Fi on Lenovo B50-10: from basic (hotkeys, system settings) to advanced (updating drivers, adapter diagnostics). You'll also learn how to determine whether the software or the hardware is at fault, and what to do if none of the methods work. The instructions are valid for Windows 7/8.1/10—the most common operating systems for this model.

Before you begin, check the obvious: is Wi-Fi working on other devices (smartphone, tablet)? If not, the problem is with your router or ISP. If so, read on.

1. Checking the physical Wi-Fi connection: keys and switches

On Lenovo B50-10 wireless modules (Wi-Fi and Bluetooth) are controlled hardware switchUsers often accidentally disable the network by pressing a key combination or a mechanical slider.

How to check:

• 🔍 Button Fn + F2 — the standard Wi-Fi on/off combination on most Lenovo laptops. Press it and wait 5-10 seconds for the system to detect networks. The indicator light next to the power button should turn blue or white.
• 🔄 Hardware switch - on some modifications B50-10 There's a small slider switch on the left or front of the case (near the USB ports). Slide it to the "On" position (usually marked with an antenna symbol).
• 💡 Wi-Fi indicator — If the light next to the power button is blinking orange or not lit at all, the adapter is turned off. After pressing Fn + F2 It should turn blue.

If the combination Fn + F2 it doesn't work, the function may be disabled hot keys in the BIOS or the keyboard drivers are not installed. More on this in the following sections.

2. Enable Wi-Fi via Windows settings

Even if the adapter is physically enabled, it may be disabled programmatically in Windows settings. Let's check this:

For Windows 10/8.1:

1. Click Win + I → select Network and Internet.
2. Go to the tab Wi-Fi.
3. Make sure the Wireless Network slider is set to On "On".
4. If there is no slider or it is inactive, the problem is in the drivers (see Section 4).

For Windows 7:

1. Click on the network icon in the tray (bottom right) → Network and Sharing Center.
2. Select Changing adapter settings.
3. Find Wireless network connection (or Wireless Network Connection). If the icon is gray, right-click and select Turn on.

If the adapter is not listed, it means Windows does not detect it. Reasons:

• 🚫 The driver is not installed or is damaged.
• 🔌 The adapter is disabled in BIOS.
• 💻 Wi-Fi module hardware failure.

3. Check Airplane mode and Windows services

Airplane mode blocks all wireless connections, including Wi-Fi. Lenovo B50-10 It can be turned on accidentally, for example, through the notification center or hotkeys.

How to disable:

• 📱 Click Win + A → find the tile Airplane mode and make sure that she gray color (turned off).
• 🔧 If there is no tile, check through Settings → Network & Internet → Airplane Mode.
• 🔄 On some BIOS versions, Airplane Mode may block Wi-Fi even after disabling it in Windows. In this case, only a reboot will help.

The problem may also lie in disabled Windows services, responsible for the network. Let's check them:

1. Click Win + R → enter services.msc → Enter.
2. Find services:
   • WLAN Automatic Configuration Service (startup type: Automatically).
   • Network connections (should be launched).

4. Update or reinstall Wi-Fi drivers

If Wi-Fi doesn't turn on either via the keys or through Windows settings, the problem is most likely in the drivers. Lenovo B50-10 an adapter is usually installed Qualcomm Atheros or Broadcom (less often, Intel). Drivers could have failed after a Windows update, a virus attack, or a system reset.

Method 1: Automatic update via Device Manager

1. Click Win + X → device Manager.
2. Expand the tab Network adapters.
3. Find the device with the names Wireless, Wi-Fi, Atheros or Broadcom.
4. Right click → Update driver → Automatic search.

Method 2: Manual installation from the Lenovo website

Automatic search doesn't always find the latest drivers. It's best to download them manually:

1. Go to Lenovo's official support website.
2. Enter your laptop model: B50-10 (or an exact modification, for example, B50-10 80ES).
3. Select your version of Windows.
4. In the section Network and wireless communications Download the latest driver for Wireless LAN.
5. Install it and restart your laptop.

Important: On Lenovo B50-10 Windows 10 often conflicts with standard Microsoft drivers. After manually installing the Lenovo driver, disable automatic updates for this device in Device Manager (Adapter Properties → Driver tab → Roll Back or Prevent Update).

5. Check BIOS settings: Enable wireless adapter

If Wi-Fi doesn't turn on using any of the methods described above, it may be disabled at the BIOS level. This can happen after a factory reset, a BIOS update, or due to a virus.

How to check:

1. Restart your laptop and when the Lenovo logo appears, press F2 (or Del, F1 — depends on the BIOS version).
2. Go to the section Advanced or Configuration (the name may differ).
3. Find the parameters:
   • Wireless LAN — it should be Enabled.
   • Onboard Wireless — included.
   • Radio Control - if there is, install it Enabled.

⚠️ Attention: If there is no mention of Wi-Fi in the BIOS, this may mean:

• The adapter is not recognized (malfunction or no contact).
• You have a laptop modification without built-in Wi-Fi (rare, but it happens).

6. Diagnostics of hardware faults

If none of the software methods helped, the problem may be in the hardware. Lenovo B50-10 most commonly encountered:

• 🔌 Disconnecting antennas — the cables running from the Wi-Fi module to the antennas (located under the laptop cover) may have come loose.
• 💥 Module burnout - after a power surge or physical damage.
• 🔋 Nutritional problems — the adapter is not receiving enough power (for example, due to bulging capacitors on the motherboard).

How to check:

1. Visual inspection:
   • Disconnect the laptop from the power supply and remove the battery.
   • Remove the back cover (you will need a Phillips screwdriver).
   • Find the Wi-Fi module (usually located next to the USB ports, looks like a small board with antennas).
   • Check if the antenna cables (black and white wires) are connected tightly.

• Power supply (the laptop does not provide enough power to operate the adapter).

7. Alternative ways to connect to the Internet

If you can't turn on Wi-Fi, but you urgently need internet, try alternative methods:

Method 1: USB Wi-Fi adapter

The simplest solution is to buy an external Wi-Fi adapter (starting at 300 rubles). It plugs into a USB port and works without installing drivers (for modern versions of Windows). Popular models:

• 📶 TP-Link TL-WN725N (compact, supports 2.4 GHz).
• 📶 ASUS USB-AC53 Nano (dual-band, 2.4/5 GHz).

Method 2: Sharing Internet from a smartphone

1. Turn on your phone Access point (in mobile network settings).
2. Connect your laptop to the created network via Ethernet (if the phone supports USB-thering) or via cable.

Method 3: Cable connection (Ethernet)

If there is a router nearby, connect your laptop to it via LAN port (RJ-45 connector). On Lenovo B50-10 It's located on the left. You'll need a patch cord (network cable) for this.
