Exceptional Speed
When coupled with a 450Mbps Wi-Fi adapter, such as the one integrated in notebooks powered by the Intel® Centrino® 2 processor, the DIR-665 provides notebook users with a faster wireless experience and greater network mobility.

Selectable Dual Band
In addition to blazing speeds, the DIR-665 offers network flexibility - the user can set the router to work in the more common 2.4GHz Wi-Fi band or the cleaner 5GHz band, which offers less network interference.

Advanced Network Security
The Xtreme N 450 Router supports the latest wireless security features to help prevent unauthorized access, be it from over a wireless network or from the Internet. Support for WPA™ and WPA2™ standards ensure that you will be able to use the best possible encryption, regardless of your client devices. In addition, this Xtreme N 450 router utilizes dual active firewalls (SPI and NAT) to help prevent potential attacks from across the Internet.

Delivering unmatched wireless performance, network security, and coverage, the Xtreme N 450 Dual Band Gigabit Router (DIR-665) is ideal for networking in the high-speed home or small business environment.
