Yeah, a lot of people end up wanting to use 802.11n and/or the 5 GHz band, but it's actually relatively easy to do that and still use the Actiontec as the primary router -- you just set the gateway on your own router and you're done.

It only gets really ugly when you decide you want something else to be the primary, at which point you have to reconfigure the Actiontec to act a bridge instead of a router, or run CAT5 to your FiOS ONT (if it's not already) and feeding that into your router's WAN port. But then your set-top boxes still want to be on the coax ONT connection so they can get guide data, VOD, and lord-knows-what-else. So it gets ugly really quickly, and the three router solution is actually the simplest one that a bunch of smart people have arrived at, which is *scary*.
