SB6141 constantly rebooting itself (10-15x per day). Event log said it was having a SYNC issue, losing connection, and rebooting. Comcast technician came out, said the signal was weak, and put a couple signal boosters in. That did not fix the problem. At the suggestion of Comcast, I purchased the SB8200 and installed it an hour ago. Same problem. I have attached the event log of the new SB8200, and the downstream/upstream reports. Are my downstream power #'s out of whack? Can someone help me figure out what is going on?
