Dude, I wish I could get that far, my Mac doesn't register my router.
The stickied Mac guide will only work for Airport routers. For other routers use the "router ip into favourite web browser" approach.
Comr4de, a few questions -
Do you have an Airport router? (or other Mac (specific) router)
Are you sure the 10.1.1.5 is your internal IP?
Does the router "save and restart" after you do this?
