Hi ,
I have the BB black Rev C with the latest release of debian. I am going through Derek Malloy's excellent book and can not connect to the internet through USB. My laptop is running Windows 10 64-bit.
With Putty I can ping 192.168.7.1 and 192.168.7.2 and get a clean response. I can do the same on my windows laptop in a cmd window..
My laptop has only a wifi connection to my internet router. Here is a photo of the device sharing window:

The Ethernet adapter Ethernet 2 has IPv4 address 192.168.7.1. ipconfig shows an Ethernet adapter Ethernet but it is listed as media disconnected.
I tried turning off Windows Defender and that did not change things. The Ethernet 2 is using Linux USB Ethernet/RNDIS Gadget, so I guess that's the private network. How do I set up sharing so the private network will see the internet??
Thanks
