How to enable Wi-Fi on a Lenovo G50-45 laptop: all the methods, from the button to the drivers.

Laptop Lenovo G50-45 — a popular model that balances performance and price, but owners sometimes encounter a problem: the wireless network suddenly disconnects or fails to turn on after a system update. In this article, we'll look at all the possible activation methods. Wi-Fi — from mechanical switches to fine-tuning Windows and driver updates.

Peculiarity G50-45 The problem is that it has a physical button for controlling wireless modules, but its operation depends on the BIOS version and the installed OS. We'll look at the options for Windows 10/11, as well as cases where the problem lies in hardware malfunctions or software conflicts.

If you're new to network setup on this laptop, start with simple methods—checking the button and taskbar. Experienced users will find the section on manually configuring network adapters and troubleshooting via device Manager.

1. Hardware Wi-Fi activation: where is the button on the Lenovo G50-45

On the body Lenovo G50-45 There is a physical switch for the wireless modules - this is a key feature of the model. The button is located on right end next to the headphone jack. It is responsible for turning on/off both Wi-Fi, and Bluetooth.

How the switch works:

• 🔄 The slider is in the "ON" position. — the module is activated, the indicator (if any) lights up blue or white.
• 🚫 Slider to "OFF" - all wireless connections are disabled, even if Windows settings show otherwise.
• ⚠️ Middle position - a malfunction is possible, it is better to move it all the way.

On some modifications G50-45 Instead of a slider, a backlit button is used—press it once to turn it on. If the indicator light doesn't light, check:

• 🔋 Battery charge (at levels below 5%, Wi-Fi may turn off automatically).
• 🔌 Connect to the network (on some laptops, the power saving module blocks the module when running on battery).

⚠️ Attention: If the slider is broken or does not lock in the "ON" position, do not attempt to repair it yourself, as this may cause a short circuit. Contact a service center.

2. Turn on Wi-Fi via the Windows taskbar

If the hardware switch is in the "ON" position, but the network still does not work, check the settings in the operating system itself. Windows 10/11 Wireless network management has been moved to the taskbar:

Step-by-step instructions:

1. Click on the icon networks (📶) in the lower right corner of the screen.
2. In the menu that opens, find the block "Wi-Fi" - If it is grey, click on it.
3. Select your network from the list and enter the password (if required).

If there is no network icon at all or it is crossed out, follow these steps:

• 🔍 Click Win + Ato open Notification Center.
• 🔄 Check if it is disabled Airplane mode - It blocks all wireless connections.
• ⚙️ Click on Network Settings for detailed settings.

Press the hardware power button|Check Airplane mode|Refresh the list of networks in the taskbar|Restart the laptop-->

If the network still doesn't appear after these steps, the problem may be with the adapter drivers or settings. Continue to the next section.

3. Check the network adapter in Device Manager

device Manager — a key tool for diagnosing problems with Wi-FiIf the adapter is disabled or not working properly, its status will be marked with a yellow exclamation point. Here's how to check:

Open device Manager in one of the following ways:

• 🔧 Click Win + X and select the appropriate item.
• 🔍 Type in Windows search devmgmt.msc and press Enter.

In the window that opens:

1. Expand the branch Network adapters.
2. Find the device with the names Wireless, Wi-Fi or 802.11 (For example, Qualcomm Atheros QCA9565 or Broadcom 802.11ac).
3. If there is a ⚠️ icon next to the adapter, right-click on it and select "Activate device".

⚠️ Attention: If there are no devices mentioning Wi-Fi in the list of network adapters, this may mean the module is physically missing (for example, if the laptop was purchased without one) or is not recognized by the system. In this case, diagnostics at a service center are required.

4. Update or reinstall Wi-Fi drivers

Outdated or corrupted drivers are a common cause of problems with Wi-Fi on Lenovo G50-45Let's look at two ways to update them: automatic (via Windows) and manual (from the official website).

Method 1: Automatic update

1. Open device Manager (as in the previous section).
2. Find your Wi-Fi adapter, right-click on it and select Update Driver.
3. Select Automatic search and wait for the process to complete.

Method 2: Manual installation from the Lenovo website

If automatic update does not help:

1. Go to Lenovo's official support website.
2. Enter your laptop model: G50-45.
3. In the section Drivers and Software Find the latest driver for Wireless LAN.
4. Download and install it following the instructions.

After installing the drivers Be sure to reboot laptop. If the problem persists, try rolling back the driver to the previous version (option Roll back in the adapter's context menu).

5. Configure power settings for Wi-Fi

Laptops Lenovo often save battery power by turning off power-hungry modules, including Wi-FiIf the network connection drops when running on battery power or after being idle, check your power settings:

How to disable power saving for an adapter:

1. Open device Manager and find your Wi-Fi adapter.
2. Right click on it → "Properties" → tab Power Management.
3. Uncheck the box "Allow the computer to turn off this device to save power".
4. Click "OK" and restart your laptop.

Also check the general power plan settings:

• 🔋 Open Control Panel → Power Options.
• 🔄 Select the active scheme (usually "Balanced" or "High performance").
• 🔧 Click "Customize your power plan" → "Change advanced settings".
• 📡 Find the section "Wireless Network Adapter Settings" and install "Maximum performance".

⚠️ Attention: On some BIOS versions Lenovo G50-45 There's a separate power saving setting for Wi-Fi. To find it, press [Enable] when booting your laptop. F2 or Del, then go to the section Advanced → Power Management and disable the option Wireless Radio Control.

6. Troubleshooting via the command line

If the previous methods did not work, use command line For in-depth diagnostics. This method will help identify hidden network adapter errors.

Open Command Prompt as Administrator:

• 🔍 Type in Windows search cmd.
• 🖱️ Right-click on the result → Run as administrator.

Run the following commands one by one:

netsh wlan show drivers

This command will display the current driver status. Note the following lines:

• Radio Type — it should be 802.11n or 802.11ac.
• Hosted Network Support — it should be Yes.

netsh wlan show interfaces

Check here:

• "State" — it should be connected or ready.
• "Radio" — it should be incl..

If you see in the results off or disabled, the problem may be in:

• 🔌 Hardware switch (check the button on the case again).
• 🔧 Driver conflict (try rolling back or reinstalling them).
• 🛠️ Malfunction of the Wi-Fi module itself (replacement required).

What to do if the netsh command doesn't work?

If you see an error when entering commands "The WLAN AutoConfig service is not running", execute:

1. Click Win + R, enter services.msc and press Enter.

2. Find a service WLAN AutoConfiguration (WLAN AutoConfig).

3. Right-click → "Launch".

4. Install "Startup Type" in meaning "Automatically".

7. Reset network settings and additional measures

If none of these methods help, perform a full network reset. This will restore all settings to factory defaults but will delete saved Wi-Fi passwords.

How to reset the network in Windows 10/11:

1. Open Settings → Network & Internet → Status.
2. Scroll down and click Network Reset.
3. Confirm the action and restart the laptop.

Additional steps if Wi-Fi still doesn't work:

• 🔄 Update your BIOS - Download the latest version from the Lenovo website and flash it using the utility BIOS Update.
• 🛡️ Check your antivirus - some programs (for example, Kaspersky or Avast) block network connections.
• 🔧 Disable VPN - services like NordVPN or ProtonVPN may conflict with Wi-Fi drivers.

⚠️ Attention: If after all manipulations the Wi-Fi indicator does not light up, but in Device Manager If the adapter isn't displayed even with an error sign, there's likely a hardware failure. In this case, the Wi-Fi module needs to be replaced (for example, on Intel 7265NGW or Broadcom BCM43142, compatible with G50-45).

Lenovo G50-45 Wi-Fi FAQ

🔹 Why does Wi-Fi turn on but not find any networks?

This may be due to:

• Incorrect region in adapter settings (change in Device Manager → Adapter Properties → Advanced).
• Channel conflict on the router (try changing the channel in the router settings to 1, 6 or 11).
• Problem with module antennas (physical damage or poor contact).

🔹 Is it possible to turn on Wi-Fi without the button on the case?
