So it sounds like you have 628 on your hr2xs. It also sounds like your system is setup to work over deca but you haven't said how your system is bridged to your home network.
A couple things. One do you have unpn turned on your router? If so its likely causing issues.
Personally as a test I'd disconnect your deca cloud from the home network, completely reset all networking settings and in all dtv boxes and then see what happens not using any fixed ip addresses or interacting with you home network. Let them get their own 169 addresses and talk to just themselves and see if anything changes. It's simple to do and may help elevate your frustration.
Thanks for the suggestions.
-My system is bridged via ethernet via the DECA Broadband connector to my home router
- I have tried previously disconnecting from the home network with the old box, that didn't help.
- I did have uPNP turned on withing the router. I'll try turning it off and see what happens (though I might need it for other applications.)
Thanks again ...
