If you want to configure your router, follow these steps:
1. Make sure you are connected to it, either hardwire or wireless
2. Open up any browser
3. In the URL bar type: 192.168.1.0 (192.168.0.1 for dlink)
4. Default for linksys routers is no username and password is admin! If you have an older one, username is home and password is admin.
5. Look around and use the setup wizards if you are new to this.
