It sounds like the interfaces are probably down. Can you get console access? Or telnet to it?

I don't console access or telnet. You mean that the interfaces are burned? and i need to replace them somehow??

No, I meant that they are probably disabled in software. If they are shut down then you can't turn them on without some form of access to the router.
Why was it only rated a B?

Sorry, I'm a beginner. Didn't understand it. I don't have access on my router, console or telnet. Is there anything else I can do??
