Or you could crash your server at home, and try to get on during the restart process.
This isn't Mission Impossible, Why would a router allow access to itself during a restart, and why would it enable access before it enables authentication? Try if you want, but not even Tom Cruise could pull that shit off.
If there were guides on the internet to hacking past passworded routers, I'm guessing the issues would get fixed. Your best bet is to whack a keylogger on someone's PC and grab it. You can even hum the MI theme tune.
