The easiest way is to log into your router. Consult your manual for the user name and password, and keep it handy. Then open up your favorite browser, and type in “192.168.1.1″, or “192.168.1.0″, and enter in the login information. At this point the steps differ for different routers. Mine, for example, you click “Logs” on the menu, and it has a page where you can view which computers accessed which site, and you can even have it email you the log on a regular basis.
