3DP Net is a utility that automatically installs your computer's network drivers even without any internet access.
As the program has a vast list of network drivers to make available to a wide list of computers, it has a relatively large size, about 120 MB.
That tool really come in handy for that moment when you format the computer and Windows does not recognize the network driver, and consequently you are unable to install the other drivers over the internet.
To use it, just download the program and transfer it to a pen drive and then move to the computer that needs the network driver. If the USB driver is also not working, you will need to burn it to a media disc to transfer the program. After running 3DP Net, the program will automatically detect the driver that your computer needs, just by clicking the "+" button to have it installed on that PC.
