Except for the fact that the four RJ45 connectors for your client devices support 10/100/1000 gigabit speed communications, the DIR-655 is an otherwise plebian device. It's a single-band (2.4GHz) router with a USB 2.0 port on the back for either USB hard disk or printer attachment. The DIR-655 distinguishes itself by being green. It optimizes its power levels depending on the length of the CAT 5e cable attached to its ports, and will also power down ports that have no attachment. It can even be programmed to shut down your wireless network when it's not in use. Price: around $90 online.
