The Streaming Sticks (3810/3811/3820/3821) require the Long Range Wireless Receiver (LRWR) to be used with them. This is what gives them the wireless capability to connect to network. (Wifi module located inside the cable, not the Streaming Stick).
If using wired connection (Ethernet adapter w/ Streaming Stick), you must have disconnected the LRWR cable (often referred to as the bumpy thing in the cable).
