Summary: It hosts four Gigabit LAN ports and a WAN port, as well as two USB 2.0 ports for connecting external drives, printers and even mobile broadband devices. Its three external antennas are flexible and removable, which is useful for finding the "sweet spot" for wireless performance. The RT-AC66U looks sleek and stylish in black, and comes with a stand or can be wall-mounted.
Pros: Excellent range, speed, Advanced features, Granular control over network
Cons: Sluggish interface, Could be more reliable, Sometimes runs hot
ASUS RT-AC66U 802.11ac Wireless-AC1750 Router Review
13 June 2013
Excerpt: Today we take a look the ASUS flagship 802.11ac Dual-Band Wireless-AC1750 Gigabit Router. Wireless AC technology has been on the market for almost a year so it is pretty mainstream and can be found in computers, mobile devices, and of course routers. We have looked at AC routers from Netgear, Buffalo, and Cisco in the past where we saw tremendous increases in wireless speeds. Most of the time, the firmware and GUI’s of these routers mirrored the non-AC routers from...
Summary: Generally, we are glad about ASUS RT-AC66U wireless router we have reviewed. It supports a cutting-edge IEEE 802.11ac wireless standard, but anyway we believe that the vendor could have used a more powerful chip set to as well surprise us with the performance level of the wired segment. We reckon that with the advent of wireless network adapters which support 802.11ac the usage of 5 GHz frequency range will become more common.
Pros: Ability to create up to three guest network in each wireless range, Support of IEEE 802.11ac, Ability to backup the uplink via 3G and 4G networks, Support of IPv6, Excellent data transmission speeds in the wireless segment of the network, A built-in PPTP server, The device boots really fast, Ability to operate in peer networks
Cons: Low routing and NAT speeds, The device deadlocks upon operation with an external HDD with NTFS, Inability to install add-ons, The web-interface is not completely translated
Excerpt: ASUS feels that its RT-N66U is a real success story. According to the manufacturer, they are selling like hotcakes. ASUS good fortune is well-deserved, because it's an outstanding router. To create the new RT-AC66U, ASUS took the RT-N66U router and replaced the 802.11n module with the 802.11ac module for the 5 GHz band. Hardware.Info tested the new router to find out how well it performs, and compared it to other current ac-routers.
Conclusion: The Asus RT-AC66U is a superb router, but it's not quite our favourite. It's very, very fast, which is great news if you only care about performance, but rivals have a few more features we'd like Asus to add.
Pros: The fastest wireless ac router yet, Excellent 802.11n speed and range, Intuitive user interface, Fast, simple setup and management
Cons: No USB 3.0 ports, Lacks true Cloud platform of D-Link/Linksys, Design not the most subtle
Asus RT-AC66U Dual-Band 802.11ac Gigabit Router review
5 December 2012
Conclusion: The Asus RT-AC66U is on a par with the excellent Cisco Linksys EA6500 11ac router. However, the two routers are best suited for two different types of customers. Those who may not be as comfortable setting up network devices, and would benefit from an almost automated setup process – and who don't need a lot of extras in terms of features – would be best served by the Linksys device.
Pros: Very impressive range, Excellent performance at 5GHz 11n, Plenty of advanced features on board, Business-class capabilities
Cons: Somewhat sluggish interface, Lost Internet connectivity a few times
