If your computer has an internet connection by virtue of a cable plugged into it from your Internet Service Provider's device, then .....
Just unplug it from your computer and plug it into the WAN port on the back of your Router.
Power up the Router and press and hold the reset button for five seconds (you'll need a paperclip, it is in a small recessed hole on the back of the router).
