D-Link just keeps upping the 802.11n ante. The Xtreme N is a vast improvement over the previous DIR-630 model. The DIR-655 bridges the narrowing gap between consumer and business Wi-Fi routers. In tests, it matched the speed of the DIR-635 nose for nose, running at 130 Mbps from very short distances with no interference, and a respectable 45 Mbps from more typical ranges and with other laptops in the room. Ubicom StreamEngine technology now handles wireless streams better, smoothing VoIP calls and online gaming. With the Gigabit ports, we moved about 3GB of wired data in just three minutes, compared with ten minutes for the Belkin N1 router.
