There are a number of other troubleshooting steps you can take, here is a list: Make sure you're using the correct IP address for the router, as well as the correct port (some use 443, or 8080 instead of the standard port 80). Also, you will most likely need a recent browser version with Javascript support.

For example, if you need to connect to in order to access the admin interface, your client PC needs to be in the range between 192.168.1.2 and 192.168.1.254. Depending on your router's configuration, you might have to connect using a LAN port, and the client accessing the administration interface usually needs to be in the same IP range.
