Like the DIR-855, the DIR-825 is a true dual-band gigabit router, meaning it can spontaneously offer Wireless-N signals in both 2.4GHz and 5GHz frequencies. The DIR-825, however, comes with SharePort technology, which allows for turning the USB port of the router into a virtual-network USB port that supports external hard drives for NAS functionality and other USB devices, such as printers.
The new router also features D-Link's HDFuel technology, and belongs to D-Link's green family of routers. The former optimizes the wireless bandwidth for HD content, while the latter means the power used for the router's wireless signal and wired-network ports are adjustable (either automatically or manually) to conserve energy.
The best news is that SharePort, as well as other technologies mentioned above, are going to be made available this week via a firmware update to certain existing D-Link USB Wireless-N routers, including the DIR-628, the, the DIR-855, and the . If you are the owner of one of these, remember to update the router's firmware.
The new Xtreme N Dual Band Gigabit DIR-825 is available now for an estimated $200.
