The first question is, what do you want the router to then connect you to ? Do you have an Internet service that you want the router to terminate, and then supply that service to your PC ? If that is the case, then you also need to ensure that the correct interfaces are present on the router, for the connection to the Internet service. If it is for something else, please let us know. If you have any information about this, please post it here (remove any personal details, or specific IP addresses or passwords).
The people on this forum can certainly help, but we do need some more information. With that we can provide a basic configuration for you, and tell you how to perform some basic tests to prove it is all working correctly. Without that information, there are too many possibilities, and it is impossible to provide a meaningful answer to your question.
