Chipsets from Atheros or Realtek, so your search should start from their official websites or MSI support archives.

The installation process requires some preparation. If the netbook itself doesn't have internet access, the drivers must be downloaded on another computer and transferred to USB driveIt is important to find the driver specifically for your version of the operating system, since drivers for Windows 7 may not be suitable for Windows 10 without compatibility mode.

After running the installer setup.exe Follow the wizard's instructions. A system reboot may be required during the process. If automatic installation fails, you will need to update via Device Manager, manually specifying the path to the folder containing the unpacked driver files.

⚠️ Note: Hardware manufacturer website interfaces change frequently. If you can't find the driver via a direct link, search for the hardware ID in Device Manager.

Manual configuration via Device Manager

If the automatic installation does not work, you will need to proceed to manual setup. Open device ManagerBy right-clicking "My Computer" and selecting "Properties," then clicking the Device Manager link. Find the "Other devices" or "Network adapters" section.

Right-click the device with the exclamation mark and select "Update Driver Software." In the window that opens, select "Browse my computer for driver software." Next, specify the path to the folder where you previously copied the driver files. MSI U135DXThe system will try to find a compatible INF file.

• 🛠 Make sure the folder path does not contain Cyrillic characters, as this may cause a read error.
• ✅ If the system offers a list of devices, select "Atheros Wireless Network Adapter" from the list.
• 🔄 After successful installation, you may need to reboot again to apply the changes.

In some cases, Windows may install a generic driver that is unstable. In this situation, it is recommended to forcefully replace it with the original driver by selecting "Select driver from a list of available drivers" and selecting the file from the manufacturer's disk. This often resolves connection issues.

What to do if the driver is not installed?

If an error occurs during driver installation, try running the installer as administrator. You can also try compatibility mode: right-click the setup.exe file, select Properties -> Compatibility, and select Windows 7 or Vista. Sometimes, temporarily disabling your antivirus software during installation helps.

Configuring network settings in Windows

After the driver has been successfully installed, you need to configure the connection settings in the operating system itself. Go to Control Panel → Network and Sharing Center → Change adapter settingsFind the "Wireless Network Connection" icon. If the icon is grayed out, right-click it and select "Enable."

For stable operation in environments with a large number of neighboring networks, it is recommended to manually configure DNS settings or a static IP address if the router does not assign them automatically. However, for most home users, leaving the default settings is sufficient. obtain IP automaticallyThis will ensure compatibility with most home routers.

Setting up a power plan is important. Windows may disable the adapter to save power, which can cause disconnects. Go to the adapter's properties, click "Configure," and then go to the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power."
