To connect a wireless router, you plug the USB cable in to the USB port, then you should go down to the bottom of your screen, (right corner) and you should see two computers linked together, if there is a red 'X' then click on it, if this isnt there, go to your start, and click all programs, and find your intenet service company and click connect to the network you want to connect to, the one you are trying to connect to (is its not yours) it could be security enabled.
