My installer told me I no longer needed the DECA setup for the Internet connection. That set up had been used on an HR21 that the 34 replaced. I left it in place with the 34 but have since removed it and just connected an Ethernet cable between the dvr and my router. The router is right next to the dvr so it's easy to do and gets rid of some cable clutter. With either configuration I haven't had any problems.
