Known Issues:

  1. These routers do not have a web UI.  Instead, Apple provides a program called Airport Utility that you have to install on a Mac or PC to configure these routers.
  2. By default, DNS relay/proxy is enabled on the Airport routers, causing intermittent phone registration failures on Polycom phones.


  1. The steps below are only required if you have or plan to purchase Polycom phones.
    • These steps will take your computer and phones offline or 5 minutes or longer.
    • You will need to reboot all network devices after the changes are done.
    • Make sure only to do the steps below when you can afford to take your network offline temporarily.
  2. Use a computer that's on the same network as your phones.
  3. See if Airport Utility is installed on your computer.  It's a program Apple provides that's needed to configure your Airport router. 
    • If you don't have Airport Utility on your computer, download and install it from Apple's website for both Mac and PC.
  4. Open up the Airport Utility > It should list the Airport router to the left > Select it and enter in the router password. 
    • If you don't know the password, contact your IT or whoever orignally setup the router.
  5. Click on Internet > TCP/IP > Change the DNS Server(s) to and
  6. If you don't see any DNS options under the TCP/IP page > click on DHCP.
  7. If there are no places where you can change the DNS on this page, then you or your IT will need to replace the Airport router with a recommended or serviceable one. 
    • Intermedia cannot help replace and configure the new router for you, but your IT or the manufacturer of your new router can. 
    • They will need to move settings from the old to the new router to ensure your computers and other devices on the network work properly.
