How to Enable Wi-Fi on a Lenovo G575 Laptop: 5 Proven Methods

Laptop Lenovo G575 — a popular model of the early 2010s with a module Wi-Fi chip-based Broadcom or Atheros, but even today, owners face problems connecting to wireless networks. Most often, the cause is a disabled adapter—either physically (using a hardware button), software-based (in Windows settings), or at the BIOS level. In this article, we'll look into it. all possible ways to turn on Wi-Fi on Lenovo G575, from basic to advanced, taking into account the features of the model.

It is important to understand: G575 It was released with different configurations, and the interface may differ depending on the BIOS version and the installed OS (Windows 7/10/11 or Linux). If your laptop doesn't see the network at all, first check Wi-Fi indicator on the body (usually an orange/blue LED next to the key F2). If it's not lit, the adapter is hardware disabled. Below, we'll look at solutions for each case.

1. Hardware Wi-Fi activation: buttons and switches

On Lenovo G575 A key combination is used to activate the wireless modules Fn + F2This is the fastest way, but it only works if:

• 🔹 Native drivers are installed on hot keys (no driver = combination does not work).
• 🔹 The Wi-Fi controller is not disabled in the BIOS (check in the next section).
• 🔹 The laptop is not in Airplane mode (error Windows 10: "Wireless is off").

How to check:

1. Click Fn + F2 once. Wait for the Wi-Fi indicator to change color (from orange to blue).
2. If the indicator does not respond, hold Fn and press F2 3-4 times in a row (sometimes the key contact is oxidized).
3. Look at the screen: a notification should appear "Wireless network is on" (in Windows 10/11 - in the lower right corner).

⚠️ Attention: On some modifications G575 (for example, with discrete graphics AMD Radeon) the hardware Wi-Fi switch is located on right end of the body — Look for a small slider next to the USB ports. If it's slid into the "ON" position OFF, the network will not turn on in any other way.

Make sure the slider on the body is in the ON position|

2. Checking BIOS settings: Why Wi-Fi may be blocked

If hardware enablement doesn't help, the cause often lies in the BIOS settings. Lenovo G575 parameter Wireless LAN It may be disabled by default (especially after a factory reset or BIOS update). To enable it:

1. Restart your laptop and when the logo appears Lenovo click F2 (or Del, If F2 (doesn't work).
2. In the BIOS menu, go to the section Advanced → Wireless (or Config → Network, depending on the version).
3. Find the parameter Wireless LAN and set the value Enabled.
4. Save changes (F10 → Yes) and reboot.

⚠️ Attention: In older BIOS versions Lenovo G575 (until 2013) the parameter may be called differently - WLAN Radio or Internal Wi-Fi. If in the menu Advanced no section Wireless, update the BIOS to the latest version (instructions in section 5).

If Wi-Fi still doesn't work after enabling it in BIOS, check:

• 🔹 Have the date/time settings in the BIOS been reset (this may block network adapters).
• 🔹 Is there a password set to access the settings? Wireless (there is no password by default).

3. Enabling Wi-Fi via Windows: Device Manager and Network and Sharing Center

If hardware methods don't work, the problem may be at the operating system level. In Windows, the Wi-Fi adapter may be disabled in Device Manager or hidden due to a driver conflict. Follow these instructions:

Method 1: Device Manager

1. Click Win + R, enter devmgmt.msc and press Enter.
2. Expand the section Network adapters.
3. Find the device with the name Broadcom 802.11n or Atheros AR9285 (depending on modification G575).
4. If next to the adapter is displayed down arrow (disabled), right click and select Activate the device.

Method 2: Network and Sharing Center

1. Right-click on the network icon in the tray (bottom right) and select Open Network and Internet settings.
2. Go to Network and Sharing Center → Change adapter settings.
3. Find Wireless network connection (or Wi-Fi) and right-click → Turn on.

⚠️ Attention: If your wireless device is missing from the list of network adapters, it means:

• 🔹 Wi-Fi driver is not installed (solution in section 4).
• 🔹 The adapter is physically damaged (check the antenna connections inside the case).
• 🔹 The PCIe controller to which the Wi-Fi module is connected is disabled in the BIOS (a BIOS reset is required).

4. Installing and updating Wi-Fi drivers for Lenovo G575

Type errors "Unable to connect to this network" or the absence of an adapter in the Device Manager in 90% of cases is related to drivers. Lenovo G575 Original Wi-Fi drivers can be downloaded:

• 🔹 C Lenovo's official website (enter model) G575 in search).
• 🔹 Through Lenovo Vantage (if Windows 10/11 is installed).
• 🔹 Manually from chip manufacturer websites:
  • Broadcom: support.broadcom.com
  • Atheros (Qualcomm): qualcomm.com/support

Step-by-step installation instructions:

1. Download the driver for your version of Windows (for example, Broadcom_WiFi_Driver_W10_x64.exe).
2. Disable your antivirus (it may block the installation).
3. Run the file as administrator (right click → Run as administrator).
4. Follow the instructions of the installation wizard. Once completed reboot laptop.

Critical information: Broadcom drivers are not compatible with the Lenovo G575 with the Atheros AR9285 chip—this is a common user error. Check the exact adapter name in Device Manager before downloading!

If after installing the driver Wi-Fi still does not work:

• 🔹 Check it out WLAN AutoConfig Service (click Win + R → services.msc → find the service and start it).
• 🔹 Remove old drivers via Device Manager → Network Adapters → Uninstall device (check mark "Delete the driver software for this device").

What to do if the driver is not installed?

If an error occurs during driver installation "Device not found" or "The driver is not designed for this platform.", try:

1. Install the driver in compatibility mode with Windows 7 (right-click on the file → Properties → Compatibility).

2. Use DriverPack Solution (carefully refuse additional software during installation).

3. Update Windows to the latest version (some drivers require updating NET Framework 4.8).

5. Troubleshooting: Why Wi-Fi Won't Turn On

If none of the methods worked, the problem may be hardware related. Lenovo G575 typical faults:

• 🔹 Oxidation of Wi-Fi module contacts (often after liquid spillage or prolonged inactivity).
• 🔹 Broken antenna cables (checked by disassembling the laptop).
• 🔹 Failure of the adapter itself (solved by replacing it with a similar module, for example, Broadcom BCM4313).

How to check the hardware:

1. Disconnect the laptop from the power supply and remove the battery.
2. Remove the back cover (unscrew the screws and carefully pry up the latches).
3. Locate the Wi-Fi module (usually located next to the RAM, under the black cover).
4. Check if the antenna cables (white and black wires) are connected tightly.
5. Remove the module, clean the contacts with an eraser and install it back.

⚠️ Attention: If you are not confident in your skills, do not disassemble the laptop yourself - contact a service center. Lenovo G575 The case latches often break when disassembled carelessly.

Software diagnostics:

1. Open Command line as administrator (Win + X → Command Prompt (Administrator)).
2. Enter the command:

   netsh wlan show drivers

   If the response contains a string "Hosted Network Support: Yes", the adapter is working properly, but may be disabled at the OS level.

3. Check the list of available networks:

   netsh wlan show networks

   If the list is empty, the problem is with the driver or antenna.

6. Alternative ways to connect to the Internet

If Wi-Fi is on Lenovo G575 It still doesn't work, you can use alternative connection methods:

Method 1: USB Wi-Fi adapter

The easiest solution is to buy an external one USB Wi-Fi adapter (For example, TP-Link TL-WN725N or ASUS USB-AC53 Nano). It plugs into any USB port and doesn't require disassembling the laptop. Average price: 500–1500 rubles.

Method 2: Sharing Internet from your phone

Turn it on on your smartphone access point (Android: Settings → Wireless & networks → Tethering & portable hotspot; iPhone: Settings → Tethering) and connect the laptop via USB or via the created Wi-Fi network.

Method 3: Ethernet via USB

If there is a router nearby, connect it Lenovo G575 to it with a cable Ethernet → USB (you need an adapter, for example TP-Link UE300). This will provide a stable connection without delays.

⚠️ Attention: When using USB adapters on Lenovo G575 With Windows 7, you may need to manually install drivers for USB 3.0 (download from the adapter manufacturer's website).

Lenovo G575 Wi-Fi FAQ

Why did Wi-Fi stop working after reinstalling Windows?

A clean installation of Windows will erase the Wi-Fi adapter drivers. Solution:
