My father has a Lynksys SR41 router with his, my step sister's computer, and a cable modem attached. Of course, his computer and my sister's computer are hookd up to the router PAN ports while the modem is hooked up to the WAN port. I was wondering if there is a way to disable her port on the router to make it impossible for her to use the cable modem at night (say 10pm - 7am), while allowing her to use the cable modem during the day? This would allow my father access to the internet 24 hours per day while giving my sister only "daytime" access.
