Router Problem

[ZebraRampage]

Well, I haven't been here for a month. My router just stopped working one day, and it hasn't worked since. I'm stuck using my dad's computer, except I'm too lazy to go on it, that's kind of an oximoron, being too lazy to be lazy by going on the computer all day. When my dad and I hook his computer which is a laptop up to the modem, the internet works fine, but when we hook the laptop up the the router, and hook the router into the modem, it doesn't work. My dad's friend took our router and tried it at his house, and it worked fine. So we think it's the computer. It's just kind of weird that it just stopped working. My dad's computer is a piece of **** though, I just hope he gets a new cpu since he has a keyboard and a monitor. I was just curious as to your opinions on this.
