Next Tuesday, the tech guy is coming to install an HR34 and set up my Whole Home system. I have a few questions about my plans before he gets here. Details: I am replacing an HR20 with the 34, and I am keeping my 21-P and 23-70 in my system. All are currently connected to the internet. One is hard wired to my router, the other two are wireless. Does it make a difference which of the DVRs is hardwired? I would prefer to put the 34 in an area of my house that requires a wireless connection, if it makes no appreciable difference. I am assuming that a wireless connection of 20-30 mbps will be sufficient. Do both the DVRs with wireless connections require a CCK? The work order only specifies one CCK; do I need to change this? Thanks in advance for your help. And if there is anything else I need to know before the truck roll, please chime in!
