More information needed...

What you have written gives us no clues to work on. You need to give more information.

1) Is Ubuntu installed on your Hard Drive?
2) How do you usually connect to your network? Ethernet? Wireless?
3) What have you tried to connect to your network?
4) What is the USB? A USB stick? A USB Hard Drive? What?
