If that question seems vague, I'm basically asking how long it takes three receivers to see each other after doing a RBR and powering a DECA? There's plenty of explanation to follow. OK, so here's my deal. I order MRV last week. Installers come on Friday and change the LNB to a SWM system. The installers also add DECAs to an HR23 and HR22, but don't finish the job because of a legacy receiver that couldn't connect to MRV (though they did upgrade a D11 to D12). Fast forward to today. Installer comes, replaces the D12 with an H24. I had also been having problems with the HR22 so he replaces it with an HR24. We hook everything up and activate MRV. We can get the H24 to see the HR24 but not the HR23; the HR23 sees the HR24 at times, others it doesn't; and in the rare instance all three receivers see each other, once the DECA is plugged in and enters the equation, none of the receivers see anything. After hours and countless RBR and system resets, we reset the HR23 to factor defaults because it had been hooked up to my home broadband network via ethernet. We once again power cycle all the units (leaving the DECA unplugged) and each receiver can see the other. But yet again (and time after time), each time the DECA enters into the equation, at least one or all of the receivers will go blind. The installer ... he just thought he was going to drop of a new receiver for me (HA!) ... spent about three hours on the phone with ISS troubleshooting. I could hear them going through troubleshooting steps until the ISS guy had exhausted all avenues. He then started to say it was probably an issue with my router and IP addresses and that the router probably wasn't issuing an address for each receiver. But that wasn't the case. I started up the dd-wrt firmware on the router and showed the installer each of the receivers as well as their IP address. So we went through the whole RBR cycle again and again. Then finally out of nowhere it began to work (I'm at work now and have been since 5 minutes after it began working). The ISS guy said the problem was probably due to the fact that there was probably so much traffic on the network that we weren't giving the system time to catch up. Does that sound right to any of you guys who are very familiar with the system? I will say this -- the installer didn't give up and though he wasn't real familiar with the intricacies of the system, he wanted to learn in case he or someone else ran up against the problem in the future.
