Here is a site that can help you with configuring your modem. http://www.portforward.com
It may not be what you are looking for but it might help diagnose the problem.Most routers have a web interface.
If you open IE
, can you insert the routers IP address
and are you then prompted for your user name and password.
If you can't get into the interface, chances are the router is toasted. See if you can ping it.
Go to Start>Run
and type in cmd
and hit return. Then, type in ping ipaddress-of-router
. Like this, ping 192.168.1.1
. If you don't get a response, it is definitely dead. Sometimes I have been able to ping a router but not open its interface. (it was dead too).
