Verdict

The D-Link DIR-665 Xtreme N 450 is a selectable dual-band Gigabit router featuring 3x3 MIMO technology that supports wireless speeds up to 450 Mbps on either the 2.4 GHz or 5 GHz frequency. Its hardware includes a 1 GHz processor, three external dual-band antennas, four 10/100/1000 Gigabit LAN ports, one Gigabit WAN port, and a SharePort USB 2.0 port for network printer or storage sharing. Key advantages include its high-speed 'HD Fuel' engine for prioritized video and gaming traffic, robust security with WPA/WPA2 and dual active firewalls (SPI/NAT), and optimization for Intel Centrino Ultimate-N clients. However, it is not a concurrent dual-band router, meaning users must choose between one band at a time, and it lacks advanced modern features such as guest network support or WDS bridging.
