I know the HR34 is supposed to function as a CCK when direct wired but with this constant of a problem and receivers dropping off the network for whole home its eather your router is kicking the units off for some reason and they can't get them selfs back on the home network or the HR34 is being stubborn and not working as a CCK for you.
Somthing to try is set up a stadic IP's with no time out on your router for the D* receivers. Or put the CCK back in the way the tech installed it and see if that solves the issue.
