This router has come out quite recently but hasn't really received much press yet. It's basically a more powerful chipset than the 610N with a better wireless performance, only difference it's not dual antenna so will only operate at one frequency (as opposed to the double priced 610N which has two radios).
Best of Both
The Dual-Band Wireless-N Gigabit Router means high performance for both wireless and wired devices. Your wireless connections are radio band selectable to avoid interference in your area, and the four built-in Gigabit ports supply high-speed connections to your wired devices.
The Power of N
Connect everybody in your home at once without wires. Dual Wireless-N radio bands let you choose the one with the least interference in your area. Either one delivers high performance for smooth streaming video, high frame-rate gaming, fast data transfers, and heavy Internet use from multiple users-- all with great range and reduced dead spots. It also connects to your existing Wireless-G, -B, or -A devices.
Access more over your network. Connect Gigabit-enabled networked storage drives, computers, printers, and other devices to the four Gigabit Ethernet ports and enjoy higher speeds than provided by routers with Fast Ethernet wired ports.
Experience coverage you can count on, all around your home. Wireless-Ns Multiple in, Multiple Out MIMO technology actually uses the signal reflections that confuse ordinary wireless technologies to boost range and reduce dead spots.
