I am attempting to connect a Nintendo Wii to my wireless router (LinkSys WRT54GS) and I am not able to get into the router to get the security code. When I open the LinkSys Advisor, it says I must be logged on as Administrator even though I am logged on as administrator. My operating system is Windows 7 Home Premium. I tried creating a user password and that did not help. Any ideas on how I can get into the router?
