Save them to a USB drive and transfer them to G505Installation must be performed in a strictly defined order: first Energy Management, reboot, then the wireless network driver, and reboot again.
☑️ Driver installation procedure
In the Device Manager (devmgmt.msc) A working adapter should be displayed without yellow exclamation marks. If you see an "Unknown device" error code, try updating the driver manually by specifying the path to the downloaded folder. Sometimes Windows 10 automatically selects a universal driver, but it may be unstable, so it's preferable to use the manufacturer's recommended version.
Diagnostics via Device Manager
A deep diagnosis begins with reviewing the hardware list. Open Device Manager and expand the "Network Adapters" tab. There should be a device with a name containing the words Wireless, Wi-Fi, 802.11 or brand names Atheros, RealtekIf there is no such device at all, the module may have become disconnected or failed.
Pay attention to error codes if they appear in the device properties. Code 10 indicates that the device cannot start, which is often resolved by discharging static electricity. Code 43 indicates a device failure, which may indicate a hardware malfunction or a critical driver error.
Try resetting the configuration. In Device Manager, click "View" → "Show hidden devices." If grayed-out network adapter icons appear in the list, remove them all. Then, select "Action" → "Scan for hardware changes" from the menu. The system will attempt to re-detect and initialize the module.
| Error code | Description of the problem | A probable solution |
|---|---|---|
| Code 10 | The device cannot be started. | Reset static voltage, reinstall driver |
| Code 28 | Drivers not installed | Installing software from the official website or disk |
| Code 43 | Device failure (resources requested) | Checking module contacts, replacing the adapter |
| Code 12 | Not enough resources | Disabling unnecessary devices in BIOS, resetting BIOS |
⚠️ Note: BIOS interfaces and settings may vary depending on your laptop's motherboard firmware version. If the described items are missing, please consult the official documentation for your revision.
Windows Services and System Settings
A special service in the operating system is responsible for wireless networking. If it is stopped or disabled, you won't be able to turn on Wi-Fi using any buttons. To check this, click Win + R, enter services.msc and find "WLAN AutoConfig" in the list.
