Ask HN: Taking control of the AirBnb router

I was recently thinking about becoming a host on Airbnb and one thing hit my mind. When you get to an Airbnb you usually would get a password for wifi. So basically taking full control of the router would be as easy as reseting and setting to the same Name/Password combination with having full control of it. I personally lack creativity and would like to hear what you could actually do with that control over router?
