My sisters laptop is completely connected to the Internet, it is sending and receiving packets. But when I go to the Internet it says it can't load any Web pages. So I tried using an ethernet cable directly into the router a day still no luck. So I brought it to my grandmother's house and it worked perfectly. And meanwhile my desktop, laptop and other devices still work on it. I've tried ipconfig commands and nothing worked so any advice on how to fix this would help.
