Have you ever changed the user name and password on this sign in? If you are not sure try the default for Linksys:
User Name: Leave it blank, don't put anything in this box
and hit "Enter"
If this doesn't work and you can't get in, you will have to reset your router and set it up again, it will have all the default settings and you will start with all new manufacturer settings. So you will have to set up the router all over again. You can reset the router by taking a pen and holding in the RESET button on the back of the router for about 30 seconds. Once you release you will lose your connection and it will need to be set up again.
