Possession of two of these devices. Currently I use the Tomato firmware to two rooms to connect wirelessly. At each device Printers, NAS and game consoles are connected by cable. On a modem is additionally connected and connect me to the Internet via VPN, the router has enough processing power for a variety of tasks. Download client to cloud services of the way to access data in the same network.
The connection between the two routers via wireless AC is excellent, in theory, both devices connect at 1300 Mbit, of course this is not achieved, but still very good 800Mbits. Although the connection via Wireless-N is not so good, but that is also due to the interference from the outside, in the vicinity are mostly 10 router on one channel, with the Tomato firmware but you can change the channel and reach therefore still good 240 MBit.
What I do not like so much the size of my old Cisco router is only half the size and even the design is not really my taste.
