Therefore, make right-click on the *Ethernet connection* with the internet and select options: + +![options](./properties.png) + +then click on the `Sharing` tab and enable the `Internet Connection Sharing` as shown below. Now, you have to select one network connection to share the internet; remember that, in my case, it is `Ethernet 3` (USB-BBB Device). + + +![share option](./share.png) + +After that, we should open the USB-Device network connection properties by right-clicking on its icon: + +![](./tcp.png) + +then select the `Internet Protocol Version 4(TCP/IPv4)` and click on the properties button; at this point, you will probably lose the connection between the BBB and Windows.
