Overview

The Sprint u770 Sprint Plug-in-Connect Tri-Mode USB is part of a new family of USB modem devices that connect as an NDIS mode network device. These modems create their own internal NAT and distribute and IP internally to the host machine. This document gives an example of how to set up and stream live using the Sprint u770 USB modem. Other NDIS mode modems may require similar procedures.
