BenchmarkReviews.com: The ASUS RT-AC66U 802.11ac wireless router builds on the success of the RT-N66U model that Benchmark Reviews also tested recently. ASUS has been busy looking to the future, and the new IEEE 802.11ac Wi-Fi standard. While it’s not officially approved, it does appear to be stable, and there are products on the market already from all the serious players in wireless networking. While 802.11n was a step forward, and many of us have been appreciative of the additional legroom that the 5GHz band allows, there is still plenty of room for improvement in Wi-Fi performance. The ASUS RT-AC66U looks great sitting on the shelf, better than the majority of routers on offer today, but it’s the higher throughput and expanded signal coverage that’s going to win over most consumers.
