Most routers will allow you to telnet into your router to gain additional information about your line.

Some routers such as the Netgears need you to enable debug mode from the web interface first,
whilst some ISP supplied routers (such as sky) have telnet disabled.

To start a telnet session

From Start >> run type "telnet 192.168.1.1" (or your routers IP address)
		Next you will need to enter the login name and password for your router.

If the login was sucessful you will be presented with the routers CLI (Command Line Interface).

Any changes you make in the CLI are done at your own risk.
