Recommendation Information

Intermedia recommends Buffalo DD-WRT routers for small business environments and home office use.

DD-WRT is an open source Linux based platform that's feature rich and freely available for use with many commercial grade routers. For more information about the DD-WRT community, check out their website.

While routers that can be converted to run the DD-WRT firmware will work fine with our VOIP products, Intermedia does not provide support for flashing a router with DD-WRT. Intermedia suggests that if you're uncomfortable with changing the firmware on your router and would like a cost-effective yet reliable router for use with our VOIP products, we advise purchasing a Buffalo DD-WRT router because this special firmware comes pre-installed.

Recommended Model:

Buffalo AirStation HighPower N600 Gigabit Dual Band Open Source DD-WRT Wireless Router (WZR-600DHP)

Available on Amazon!

  • Buffalo routers are known for their high-quality and wireless network reliability.
  • Make sure you do not get a Buffalo router with stock firmware! Those have not been tested and are not nearly as feature rich as those provided by the open source DD-WRT firmware!
    • Please ensure that you do NOT purchase the "DD-WRT NXT" version of the software. This is a stripped down version of DD-WRT with far less robust configuration settings.
  • These routers have Advanced Bandwidth Control, which were effective at resolving call quality problems due to bandwidth overutilization.

Known Issues

  1. None at this time. If you are having problems with your Buffalo router, please contact Buffalo technical support.
