Internet Connection Sharing over Ethernet in Windows
By default the WiFi Pineapple is expecting an Internet connection from 172.16.42.42 on its LAN. Connect the WiFi Pineapple LAN port to the Windows PC host. On the NANO this is the male USB A plug. On the TETRA this is the USB ETH port.
Open Control Panel > Network and Internet > Network Connections
