Hi. I have a Linksys WRT54G wireless modem. My DSL modem is a Westell 6100. I'm using Windows 7. I'm trying to change my security settings so I can use my wifi with my Nintendo DS. In order to do that, I have to acess my router. When I go to 192.168.1.1, I just go to my MODEM settings. I can't figure out how to just get to my router. Also, I need a password and username to access anything on my modem, but nothing I've tried works. Please help?
