Modem log errors: Time sync & REG-RSP-MP
Been getting these errors on my brand new Arris SB8200. I first noticed this because I had a warning on my modem interface saying that the time was out of sync. Sure enough, my modem is 1 hour behind and no matter how many times I try resetting it, nothing fixes it. I also noticed that it is not connecting to DOCSIS 3.1 on the upstream (is that even available?). Below are my logs and stats on my downstream/upstream. Connectivity to the internet seems to be ok most of the time and it hasn’t seemed to have lost any connection on its own since I installed it. Still, the error messages don’t give me a lot of comfort. Any help would be appreciated.
