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.<br />
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??

Why the leds of serial and ethernet ports does not light up afer a restart?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
