Anyone heard of it? In the CC ad, it states 4X the range and 12x the speed of wireless-G(which I have now).
I could use more range as the router is at one end of the house.

the half duplex nature of wireless and the actual throughput it has from client to ap would make gig on the wired side absolutely worthless! even at 100mb you arent even getting close to maxing out the throughput on the ethernet side. the only thing 802.11n is really does over the other 802.11 specs is that it is fixing multipath in the signal from the antennas by utilizing multiple antennas to triangulate clients and create a temporary point to point connection rather than flood the area with weaker signal. Regardless of its increased transfer rate things you have to keep in mind is for one you are still riding the horrendous 2.4ghz spectrum with only 3 usable channels that is incredibly congested, and 2 just like how g is crippled by backwards compatibility to b in its backoff algorithms n is not going to be any better.
