I got DECA installed yesterday, so I am not sure if this is related to the current firmware or not. Immediately after the DECA installation when I restarted the H24-700 it had a 771 searching for signal. My HR21-100, HR22-100, H23-600 and D12 were all working fine. The installers changed the connector in the wall and the H24 picked up the signal was working. This morning when I woke up it was back to 771. I swapped the position of my H24 and H23 and the H23 is working in the spot where the H24 was not and the H24 is not working where the H23 was working. Any suggestions?
