And it was worth the wait.
The reason for the holdup was the router's initial versions of the firmware had a few known bugs. I tested it with the latest, version 18.104.22.168.108, and while I could still find some minor quirks, the router proved itself to be one of the best N900 routers on the market.
The RT-N66U now support the latest 3 by 3 standards of the N specification and offers up to 450Mbps on both bands, simultaneously. It is especially excellent in the 5Ghz band in terms of data rate. Both bands, however, offered great range and very stable signals in my testing.
The router comes with two USB ports that can do a lot more than just hosting external hard drives or printers. You can also use a cellular USB dongle with them for backup or mobile Internet sharing. The router even includes a comprehensive PC-less download feature.
With the built-in Traffic Manger and QoS features, the RT-N66U is great for home users. It's also great for small businesses, however, thanks to the built-in VPN server that allows for up to 10 remote connections.
