With the Offline Scan feature, you can update your network drivers using Driver Easy even when your computer cannot connect to the Internet.
To update your network drivers when your PC doesn’t have a network connection, you need to use the Offline Scan feature on your PC to scan your hardware device and export the device information of your network adapters.
Then you’ll need to upload the device information of your network adapters on another computer that has network connection using the Offline Scan feature of Driver Easy. Driver Easy will automatically find the correct network drivers for your network adapters.
