|Are you sure it is the 'netgear support page' you are getting to? - if the ip address wasn't correct you would get a message saying that, it would not redirect you to the netgear site, especially as you haven't apparently got internet access. Recheck the page you are getting to, it may look like a support site, but it could be the actual front page to your router setup.|
Failing this, is it a brand new router? If it is 2nd hand then the previous owner may have changed the access ip address, all you need to do is look for the little reset pin button on the rear to set it back to default.
