You've got to have either a modem or a router or a switch. These days I presume a router, but if it's a modem with a single ethernet port and a wired connection I'd still see if your ISP might be able to help you figure out what's happening (and, believe me, I know that this can be like pulling teeth - I've been there). Since this sounds like it's happening at home, I'm not presuming a switch.
It makes no sense (as you've already said) that the same button on the same website on the same computer using the same web browser works when you're activating it using one internet connection and does not when you're using another. And I agree that, given the number of "sames" the only different is something between your computer and the website.
