Popular Buffalo WZR-HP-AG300H 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 WZR-HP-AG300H 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 E3000 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.
