Some devices absolutely need an Internet connection to set up.

I purchased a Fibre Cloud Gateway (which is being given away), and there is exactly nothing you can do with it before you connect it to the Internet. It doesn't even let you begin setting it up.

So DHCP or go home?

No, I think it lets you set up the connection. I can't remember in detail but I had no issues setting it up on PPPoE (excluding the fact that the connection requirement is itself an issue).
