Introduction

The D-Link DIR-821 is a wireless IEEE 802.11ac compliant device that delivers up to 3x faster speeds than 802.11n while staying
backward compatible with 802.11n/g/b/a devices. This means you can connect the DIR-821 to a cable or DSL modem and
provide high-speed Internet access to multiple computers, game consoles, and media players. You can create a secure wireless
network to share photos, files, music, videos, printers, and network storage. Powered by 802.11ac technology and equipped
with four external antennas, this router provides superior wireless coverage for larger homes and offices, or for users running
bandwidth-intensive applications. The DIR-821 also includes a 4-port 10/100 Fast Ethernet switch that connects to wired
devices for uninterrupted video calling and faster file transfers.
The DIR-821 supports the latest wireless security features to help prevent unauthorized access, be it from over a wireless
network or 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 router is equipped with a dual-active firewall (SPI and NAT) to
prevent potential attacks over the Internet.
