1. Update the Driver from Device Manager
2. Install Updated Drivers from the Manufacturer’s Website
If Windows is unable to find updated drivers or if you want to update the driver manually, you can download the latest drivers directly from the manufacturer’s website. If your computer can’t connect to the internet even via an Ethernet cable, don’t worry. Use another computer with internet access to download the updated drivers by repeating steps 1–3 from Method 2. Once the driver package is downloaded, copy it to a USB drive or other portable storage device. Plug the storage device into the affected computer, transfer the installation file, and run it to install the new drivers. After the update, restart the computer to see if the problem is fixed. If you still cannot update the drivers for your network adapter, or if no new drivers are available, or if updating does not resolve the issue, there is another solution that has worked for many users—starting the Radio Management Service.
