One of the more powerful DD-WRT routers, the D-LINK DIR-825 N600 offers everything a home or small business needs in a high-bandwidth network for DSL, cable, and fiber optic connections. This dual-band device utilizes 4 Gigabit LAN ports, 2 powerful antennae and a networked USB 2.0 port for external storage devices. It provides maximum networking integration and speedy wireless performance.

The D-LINK DIR-825 FlashRouter is one of the few dual-band DD-WRT routers with external antennae. The DIR-825's external antennae allow you to upgrade further to more powerful high-gain antennae that provide extended distance options for your wireless network. The 5 GHz channel is the recommended method for connecting to streaming video services. The 5 GHz band is more powerful but works over a shorter distance than the standard 2.4GHz band. The DIR-825's 680Mhz Atheros brand processor provides impressive computational power in handling high-bandwidth traffic. MIMO (Multiple Input, Multiple Output) technology produces excellent wireless coverage by optimizing data flow through the antennae for sending and receiving information.

Popular DIR-825 DD-WRT Setup Options

Using DD-WRT can make your network infinitely more stable and easier to tweak. FlashRouters creates a complete out-of-the-box, plug and play DD-WRT upgraded router solution that includes all the most popular DD-WRT features:

  • VPN Router: Upgrading to a DD-WRT DIR-825 allows for built-in VPN connections with OpenVPN and PPTP, creating a secure tunnel for any device just by connecting to the router. When you use a Virtual Private Network (VPN) connection, you get an additional layer of Internet security and encryption that allows you to mask your location or to access regionally restricted video and streaming content. Read more about what VPN can do under the VPN Service tab.
  • Dual Router Setup: In the dual router setup, one router is connected to your local Internet Service Provider and the DIR-825 can be used as a dedicated VPN router. Learn more about the FlashRouters Dual Router Setup.
  • Wireless Extender/Bridge Options: Depending on your build and chip type, you can set up a variety of wireless extender options with a DD-WRT router. This will allow you to extend the current reach of the router, improving wireless range in homes and offices. You can also use DD-WRT to create a wireless bridge. With a wireless bridge, you can establish a wired connection without running actual cables and you can create wired ports for a 3G/4G MiFi device. Get a more extensive breakdown in our post on Wireless Repeaters and Bridges. Please look under the Support Plan tab for additional tech support information if you plan to use one of these setups.
