I think you would have to deliberately break your modem. That is and I make no apology for the industry that has expectations that everyone is a TCP/IP guru as I write how to break it.
In the router, configure it to hand out bum DNS entries of a netmask of 0.0.0.0. Then on your machine, manually assign good numbers.
Again, this may go right over most folk's heads. And if so, nod again to OPENDNS and the Apple Mac's PARENTAL CONTROLS.

I have an Airport Extreme Base Station and am wondering if there's a way I can block certain devices such as a Mac from connecting to this router or using the internet? It's okay if I simply block them from the router but would like the option for it to connect to the router such as using the printer but I want to block the internet. Is this possible?
Thanks
