Verdict

The ASUS RT-N66U, known as the 'Dark Knight,' is a dual-band N900 gigabit router featuring a 600MHz Broadcom processor, 256MB of RAM, and 32MB of flash memory. It supports simultaneous 2.4GHz and 5GHz bands with speeds up to 450Mbps on each, and includes five Gigabit Ethernet ports (1 WAN, 4 LAN) and two USB 2.0 ports for printer or storage sharing. Its main pros include exceptional wireless range, a user-friendly ASUSWRT interface, and support for up to 300,000 concurrent data sessions, making it highly stable for heavy multitasking and gaming. However, some users have noted that the unit can run quite hot during operation and that its 2.4GHz performance may be less impressive than its 5GHz speeds.
