Technically, they're not forcing you to use the bundled router. You're free to use your own router, but then, you couldn't do IPTV and that about it. So, if you think IPTV is bollocks (which I think it is for now), then, just use the Belkin that you've. For now, I'm using the DIR-615 as a network bridge as per the guide by rizvanrp and use my own Buffalo WZR as my main router & AP. No problem there.
