BIOS Magazine published a review on the D-Link Wireless N Gigabit Router (DIR-655)

If you're looking for Draft 802.11n speeds (naturally, D-Link recommends that you pair the DIR-655 with its Xtreme N Notebook Adapter performance) and greater coverage for your entire home or small office, D-Link's DIR-655 should be at the top of your list. Draft 802.11n isn't a great leap in performance though, and in out tests we could only manage a wireless speed (from a Draft 802.11n-enabled laptop) of 48.9Mbit/s from 6-feet away. Moving the laptop two rooms down our office resulted in a drop of speed to 27.5 Mbit/s. Nevertheless the DIR-655 sports a raft of configuration options, has a configurable QoS engine, and the extensive list of preconfigured applications in the port forwarding setup are greatly appreciated. And now it even has Gigabit Ethernet LAN ports. Highly recommended.
