I suppose you are referring to a USB modem with Ethernet output, ie having two types of connections ..

Check if your Ethernet card is installed drivers and correct (without conflicts) in the device manager (network adapter) and check the status of the connection if it were disconnected and the properties of the connection check added "protocol Internet TCP / IP. "

And a little more specifically what you want and what steps you tried well as the model of modem you have and what kind of service you receive from your ISP (Internet server)
