[sudo-sys] We need access to our router/AP

Does anybody know how our router works? Does anybody have access to it? I have been asking around for weeks and it is still not clear to me... We are about to switch from Sonic.net to LMI. They are both running concurrently at the moment, but Sonic service will end soon. They are both static IP, so we need to access the router before we can start using the new service. Ping Wolfy? :)
