I'm using this with a Verizon-supplied Actiontec router with the router's WiFi radio disabled. Setup was trivial. Speed is quite adequate for my FiOS Internet connection; though I only have one 802.11ac client on the network and can't really test the internal network speed there.
802.11ac support; theoretical maximum of 867 Mbits/s on 5GHz band; easy setup; on/off switch; good price
Range on 5GHz band could be better; plastic case
