Laptop Lenovo B50-10 — a popular model among budget devices, but owners often encounter the problem of disabled Wi-Fi. The causes can vary: accidental keystrokes, driver failure, hardware lock, or even a virus. In this article, we'll look into the issue. all possible ways to turn on Wi-Fi on this model - from basic to advanced.
It is important to understand that Lenovo B50-10 was released with different configurations of network adapters (for example, Qualcomm Atheros or Broadcom). The methods for enabling Wi-Fi are universal, but in rare cases, unique drivers may be required. If, after all these steps, the network still doesn't work, the problem is most likely in hardware failure (for example, antenna failure or module failure).
Before you begin setting up your router, make sure it's working properly (check the connection on other devices). Also, check the Wi-Fi indicator on your laptop—if it's on, does not glow at all, this may indicate a hardware blockage or lack of power to the module.
1. Turn on Wi-Fi using a key combination
The fastest way is to use hot keysOn . Lenovo B50-10 The combination responsible for activating wireless networks Fn + F7 (or Fn + F2 on some modifications). Button F7 usually marked with an antenna or airplane icon.
How does this work:
- 🔹 Press and hold the key
Fn(in the lower left corner of the keyboard). - 🔹 Without letting go
Fn, press onceF7(orF2). - 🔹 Look at the Wi-Fi indicator (next to the keys or on the front panel of the laptop) - it should light up or change color.

Fnnot locked (some models have a separate button)Fn Lock). - 💡 Check if the program is installed on the system Lenovo Energy Management - It can block the keys.
⚠️ Attention: On some versions Lenovo B50-10 (especially with Windows 8 pre-installed) combination Fn + F7 may not work due to a conflict with Lenovo Quick ControlIn this case, try updating the utilities from the official website.
2. Check the adapter status in the Network and Sharing Center
If hotkeys don't help, the next step is to check if the Wi-Fi adapter is enabled in Windows. To do this:
- Right-click on the network icon in the tray (lower right corner of the screen) and select
Network and Sharing Center. - In the left menu, click
Changing adapter settings. - Find in the list
Wireless network connection(orWi-Fi). - If the icon is grey, right-click and select
Turn on.
If the adapter is not listed or is marked with a cross, this may mean:
- 🔌 The driver is not installed (go to section 4).
- 🔧 The adapter is disabled in BIOS. (section 3).
- 💥 Hardware failure (diagnostics required).
Also, pay attention to the connection status. If there's an exclamation mark next to the network name, try:
- 🔄 Reboot the router.
- 🔑 Check that you entered your password correctly.
- 📡 Change the Wi-Fi channel in the router settings (for example, with
caron6or11).
☑️ Wi-Fi adapter diagnostics
3. Enabling Wi-Fi in BIOS (if the adapter is blocked)
In rare cases, the Wi-Fi adapter may be disabled at the BIOS level. This typically occurs after a factory reset, a BIOS update, or a virus attack. To check:
- Restart your laptop and when the logo appears Lenovo click
F2(orDel,F1— depends on the BIOS version). - Go to the section
Advanced→Wireless(orNetwork,Onboard Devices). - Find the parameter
Wireless LAN(orWLAN,Wi-Fi) and set the valueEnabled. - Save changes (
F10) and reboot.
BIOS appearance on Lenovo B50-10 may vary. Here are approximate paths for different versions:
| BIOS version | Path to Wi-Fi setup | Parameter to enable |
|---|---|---|
| InsydeH2O (the most common) | Advanced → Device Options |
Wireless LAN or WLAN Radio |
| Phoenix | Advanced → Built-in Device Options |
Wireless LAN Controller |
| AMI | Advanced → Onboard Devices Configuration |
Wi-Fi or Wireless Network |
⚠️ Attention: If there are no Wi-Fi-related settings in the BIOS, this may mean the adapter is not detected by the system (for example, due to a power failure or physical damage). In this case, diagnostics at a service center are required.
4. Installing or updating Wi-Fi drivers
One of the most common scenarios is the absence or incorrect operation of drivers. Lenovo B50-10 There may be adapters from different manufacturers, so it is important to download the correct version.
Method 1: Automatic update via Device Manager

Is it possible to replace the Lenovo B50-10's Wi-Fi module with a more powerful one?
Yes, but with some caveats:
- The laptop supports modules of the format
mPCIeorM.2 (Key A/E)(depending on the motherboard revision). - Maximum compatible models:
Intel 7260,Atheros AR9485,Broadcom BCM43142. - For modules with support
5 GHz(For example,Intel 8260) antenna replacement may be required. - After replacing the module, be sure to install the drivers from the official website of the adapter manufacturer.
A new module costs between 800 and 2,500 rubles. It's best to entrust the replacement to a specialist, as it requires careful disassembly of the laptop.
The Wi-Fi works, but the speed is very slow. How can I speed it up?
Problems with speed on Lenovo B50-10 usually associated with:
- Outdated driver - update it to the latest version.
- Overloaded router channel - change the channel to
1,6or11in the router settings. - Weak signal - move closer to the router or use a repeater.
- Adapter limitations - if you have a module
1x1(For example,Atheros AR9485, maximum speed is 72 Mbps).
Also, check your router settings to see if anyone else is using your network. If many devices are connected, this can slow down your speed.
