Having some trouble with my WHDVR and Internet playing nice together. Here is my setup: HR21/100 with my Internet router plugged into the bottom network port and a DECA plugged into the top network port and the single coax port. HR24/100 (which I just got to replace a failing HR20) with only the coax attached only. H24 with only the coax attached. With this setup my WHDVR works fine and all three boxes can see the Internet and access services, do VOD, etc. What I WANT to do (and tried to do) is switch the HR24 and HR21 locations so that I ended up with my Internet router plugged into the HR24's single network port and my HR21's DECA plugged into the top network port but nothing in the bottom. When I do this, the boxes cannot see each other via the WHDVR and I get messages that it detects other boxes on the coax network and that I should remove the Internet connection, restart and go from there. From all this then does the HR21 bridge the Ethernet to to the coax network and the HR24 not? Since I assumed that the HR24 has a built in DECA and didn't need an external one. Or am I missing something? A piece of equipment?
