Unlike modern models, where control is often software-based, physical contact is essential here. On a laptop keyboard, usually in the top row of function keys (F1-F12), there's a button with an image of an antenna or airplane.
To activate the function you will need to hold down the key Fn, located in the lower left corner, and simultaneously press the corresponding function key (most often it is F5 or F7, but on the G505 model this may vary).

If the key combination doesn't respond, the problem may be due to a missing hotkey driver. Without special software Lenovo Energy Management or Lenovo Utility The operating system may simply not perceive pressing the function keys as a command for the network adapter.
Software activation via the Windows interface
If the physical buttons don't help, you should check your operating system's software settings. In Windows 10 and 11, network interface management is located in the Action Center and Network Settings. Click the network icon in the lower-right corner of the screen (near the clock) or use a keyboard shortcut. Win + A to open the quick action bar.
There should be a tile labeled "Wi-Fi" or "Wireless Network." If it's grayed out or missing, click it to activate it. In older versions of Windows or with certain interface settings, you may need to open the full settings menu. To do this, right-click the network icon and select "Open Network & Internet Settings."
In the window that opens, find the wireless network status switch. Make sure it is set to the "On" position. OnIt's also worth checking that Airplane Mode isn't activated, as it disables all radios, including Bluetooth and Wi-Fi.

In the network settings, find the "Reset network" link at the very bottom of the page. This will reset all components to their factory defaults, which often resolves the issue of the adapter not being visible.
Configuring the adapter in Device Manager
A deeper level of control over the equipment is provided device ManagerThis tool allows you to see how the system sees your network adapter and identify software errors. To access it, right-click the Start button and select Device Manager or enter the command devmgmt.msc in the Run window.
In the window that opens, find the "Network Adapters" section. Expand it and look for a device with the words "Network Adapters" in its name. Wireless, Wi-Fi, 802.11 or names of chip manufacturers such as Atheros, Realtek, BroadcomIf the adapter is displayed with a yellow exclamation mark, the driver is not working correctly or is missing.
☑️ Diagnostics in Device Manager
Double-click the adapter to open its properties. Go to the "Driver" tab and check its status. If the "Enable" button is active, the device has been disabled by software and needs to be enabled. You can also try clicking "Update Driver" and selecting "Automatic Search," although this may not work. Lenovo G505 Manual installation is often more efficient.

In the adapter properties, also check the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power." This will prevent Wi-Fi from disconnecting when the laptop goes into sleep mode, a common issue with this model.
Installing and updating drivers
The key point in the work Lenovo G505 The presence of the correct drivers is crucial. This model was released during the era when Windows 8 and Windows 7 were mainstream, so drivers may not install correctly automatically on Windows 10/11. You'll need to find a driver specifically for your wireless card's chipset.
You can determine the chip model through the Device Manager (Details tab, Hardware ID property) or using the utility CPU-Z. For Lenovo G505 most commonly used modules are from Atheros or RealtekIt's best to download drivers from the official Lenovo support website by entering your device's serial number or selecting your model from the list.
Driver installation sequence:1. Remove the old driver through Control Panel.
2. Restart the laptop.
3. Install the Chipset driver (if available).
4. Install the Wireless LAN driver.
5. Reboot the system again.
If there's no official driver for your version of Windows, you can try installing the Windows 8 driver in compatibility mode. To do this, right-click the installation file, select "Properties" → "Compatibility," and select the desired OS version.
- 💻 Determine the exact model of your wireless adapter.
- 🌐 Download the driver from the manufacturer's official website.
- 🔄 Uninstall the current driver through "Programs and Features".
- 📥 Install the new version and restart your laptop.
Windows services and protocol settings
Even with working hardware and drivers, Wi-Fi may not work due to disabled system services. In Windows, the "WLAN AutoConfig" service is responsible for wireless connections.WlanSvc). If it is stopped, connecting to networks will be impossible.
To check, click Win + R, enter services.msc and press Enter. Find "WLAN AutoConfig Service" in the list. Double-click it to open the service properties. The Startup Type should be set to "Automatic" and the Status to "Running." If the service is stopped, click the "Start" button.
| Service | Launch type | Status | Impact on Wi-Fi |
|---|---|---|---|
| WLAN AutoConfig Service | Automatically | In progress | Critical (Wi-Fi won't work without it) |
| Network List Service | Manually | Stopped | Average (affects the display of lists) |
| NetBIOS Helper Module | Manually | In progress | Low (needed for older networks) |
| Disk Encryption Service | Manually | Stopped | No influence |
It's also worth checking your TCP/IP settings. Go to "Network and Sharing Center" → "Change adapter settings." Right-click "Wireless Network Connection" and select "Properties." Find "Internet Protocol Version 4 (TCP/IPv4)" in the list and make sure the "Obtain an IP address automatically" and "DNS" options are checked if your router assigns them automatically (which is the case 99% of the time).
Diagnosis and solution of typical problems
If none of the above methods helped to turn on Wi-Fi on Lenovo G505Perhaps the problem is more specific. Users often forget about the BIOS, where the integrated wireless module can be disabled at the motherboard level.
