Ok, I have checked the error message and it says coax not connected(9) and Internet not connected (13). Then I found a cat 5 cable long enough to reach from my router to the HR34 and plugged it into the back of the unit. I went thru the test setup, repeat setup, restore defaults and rebooted the HR34. Still no connection. It is difficult for my to pull one of the HR24s out to swap with the HR34 due to the way they are installed. I will try in the morning. But does this testing with a direct Ethernet cable connected tell me anything?
Again thanks for everyone's patience!
Assuming that the cable is good, it tells you, your HR34 has failed. it also suggest to me that you got a significant spike on your coax cable. Was there a storm or something the night before this happen? I'd look at your surge suppressors.
Did you happen to look at the router after it booted? Did the router show that the cable was connected?
I'm sorry but I think you will need to replace it...
