Why would you restore settings that are not working ??
My suggestion would be to reset back to factory defaults & then go through the set up process described as though you just purchased. This
link has an automated set-up process, click on the Easylink Connect link & down load the executable.
EasyLink Connect is a first-time setup application that automates the setup of your Linksys router, including:
