Hi guys, I have been a long time reader of the site, and wanted to throw my two cents into the mix regarding this powerhouse router.
My previous routers were a Linksys E4200 and a E4200v2. I wanted the end-all-be-all of routers and was told about the N66U. I found one on sale for $179.99 here in canada and immediately picked one up. I configured it with basic settings running .90 firmware (I now am running .102)
I use a 50Mbit/2Mbit connection at home, and have 2 PCs (1 wifi, 1 ethernet), 3 Laptops (all wifi), 1 iPad, PS3, Xbox360, AV receiver and Smart TV all running off my home network. I keep my router in the basement in my media room where all my cable, satellite and phone connections are. I also have a 1400 sq foot house and let me tell you, from the routers position, I get coverage in every nook and cranny of this place. I find the ASUS gets full reception in all rooms, whereas the E4200 would get at the most 4 bars in at the farthest office, and oddly the E4200v2 got 3 bars. In fact I stay connected at 150mbps on the farthest PC from the router.
I have not had a hiccup streaming anything to and from any PC so far, nor have I had an issue with the media server via a connected USB drive.
I definitely prefer this router over the E4200 and 4200v2 (actually I prefer the original 4200 over the V2 for connection reasons. At my furthest PC I consistently get this speed test through my wifi connection on the N66U...

I was getting about 40 down with my E4200 and no more than 32 down through my E4200v2.
So in conclusion, I 100% endorse this router and anyone would be happy to own one. Also please dont pick this review apart. I dont review things very often, nor am I super tech when it comes to power levels, VPN, etc. Just want you all to know that on the basic levels that I at least use it for, I love this router!
Take care guys!
