Asus RT-AC66U 802.11ac Wireless Router
The Asus RT-AC66U shares its outward appearance with the RT-N66U, with the same crosshatched pattern and trio of external antennas. Even under the skin, eagle-eyed users will notice that certain components are shared with its predecessor. The biggest difference here is the new 5 GHz radio, which should come as no surpise considering that 802.11ac focuses on the 5 GHz band. Performance is strong - according to SmallNetBuilder's testing, the RT-AC66U is one of the fastest 802.11ac routers on the market today. Whereas previous "draft 802.11ac" versions suffered from reliability issues, the latest firmware updates have just about erased this drawback. As with its predecessors, the RT-AC66U seems especially well-suited for gaming, given its high throughput speeds and above-average reliability. Despite the high price, the RT-AC66U is easily one of the gold standards amongst 802.11ac routers.
