Open a web browser like internet explorer or Netscape. Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has http://www.google.com in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 192.168.1.254. Then hit "ENTER".

You should see a box prompting you for your username and password. Enter your username and password now. By default both the username and password are blank. Click the Ok button to log in to your router. That should get you in, but if you get kicked out, because of wrong username or password. On the back of the router should have reset switch or button in a small hole. Press and hold that for about a minute. Should reset to factory default. Sorry forgot to say that you will need to use a paper clip to fit into reset switch. The big paper clip is the best and it needs to be straighten a little.
