What exactly was the configuration change done before this problem started ? Did you try to restart the router and try it ?

If not, then you will have to follow the 'password' recovery procedure and then you'll be able to login to the router without any configuration, which will allow you to take a look at the existing configuration on the router. Follow the link and do this, post the configuration;
