Known Issues

  1. DNS server addresses need to be changed to set of efficient DNS servers, like Google's DNS or another DNS, to prevent intermittent registration failures on Polycom phones.
  2. WAN ping response to our Call Quality Monitoring and Troubleshooting Servers needs to be enabled.

Temporary Resolution

  1. The custom DD-WRT firmware allows many incompatible WRT54G-series routers to become compatible.
    • However, Intermedia cannot install the custom firmware on your router for you.
    • A layout of the DD-WRT interface can be found here.
  2. Perform the standard DD-WRT router changes to make these routers compatible.

Permanent Resolution

  1. Make sure your router model is stable with DD-WRT by reviewing the table below.
  2. If your model is not supported or stable with by DD-WRT:
    • Replace your router with a different serviceable or recommended router if you do not have one already.
    • Intermedia cannot setup the new router for you, but your IT or the manufacturer of your new router can assist you. 
    • 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.
