My Maestro will connect via Smartlink on an iPhone hotspot (Verizon) with poor quality, but will not connect with my 6400 over Cox Cable (the 6400 is on a CenturyLink DSL system). When running the Maestro on Cox remotely I can see the radio, but it will not connect, in spite of a network test green light. Flex iOS will not connect via Cox either, but will connect via the cellular network After much troubleshooting Help Desk has told me that some ISPs interfere with the Flex data stream and there is no remedy so far. They suggest that I might be able to connect using a VPN bridge consisting of two dd-wrt routers, one on each end. Has anyone else had this problem and did you find a solution?
