Make this router stop!!!

It's like everyday the internet connection always get lost because of the router. And then I get tired of waiting for the internet connection to reset. My brother doesn't want me to do it but he says he can, just because of his XBOX 360, and I can reset the internet connection. This is why I wasn't online much on DrawingNow today. And for today, this actually happened like two times. So do you think I should buy a new router, or should I just keep it? I even go on to safe sites from virus.
