Installing and updating Wi-Fi drivers
Lack of drivers is the most common reason for non-working Wi-Fi on ASUS X550CThis model often came with Windows 8 preinstalled, and when upgrading to Windows 10 or 11, the standard Microsoft drivers may not support all module features. You'll need to find and install a specific driver package.
The manufacturer's official website may not contain drivers for new operating systems, so sometimes you have to use Windows 8 drivers in compatibility mode. Critical determine the exact model of the wireless module, since different batches of laptops were equipped with chips from Atheros, Realtek or Broadcom.
devmgmt.mscEnter this command in the Run window to open Device Manager. The name of your Wi-Fi module should be displayed under "Network Adapters." If the name is "Unknown Device" with a yellow triangle, the driver is not installed or is not working correctly.
| Module manufacturer | Typical name in the system | Recommended driver version | Support status |
|---|---|---|---|
| Atheros | Atheros AR9485 | 10.0.0.238 (Win 8/10) | Basic |
| Realtek | Realtek RTL8723AE | 2016.4.12 (Win 10) | Full |
| Broadcom | Broadcom 4313 | 6.30.223.219 | Limited |
When installing drivers manually, always select the "Use a previously installed driver" or "Update manually" option, specifying the path to the downloaded file. Automatic search via Windows Update often fails to find specific versions for older chipsets. ASUS.
Where can I download drivers if they are not on the official website?
If the ASUS website doesn't have drivers for your version of Windows, try searching for them on the chip manufacturer's website (Atheros/Qualcomm, Realtek) using the hardware ID. You can find the ID in Device Manager by opening the properties of the unknown device on the "Details" tab.
Diagnostics via Device Manager
Deep diagnostics help identify hidden hardware conflicts. Device Manager not only displays driver status but also controls the adapter's power supply. Often, the problem stems from the system shutting down the device to save power and failing to wake it up properly.
Open your wireless adapter's properties and go to the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power." This will prevent Wi-Fi from disconnecting when idle.
- 🔍 Check the "Driver" tab and make sure the "Roll Back Driver" button is active (this means the driver is installed).
- 🛠 Try clicking "Remove device" and then selecting "Scan for hardware changes" from the action menu.
- 📝 Write down the error code if the device status says "This device cannot start (code 10)".
⚠️ Warning: If the error code changes after each reboot, there may be a hardware interrupt conflict or a physical fault with the Wi-Fi module inside the laptop.
