As stated by Jinteik, that is the beginning of it. What you can do is go to http://www.lynksis.com and download the handbook version of the type of router you have and you will have all of your answers there. I always had a copy on my computer when I worked the help desk and sent it to my customers. Also be sure to CHANGE the default settings. If not, the war driving hacker will just love you…
