Arris SB8200 Problems
Hello,
I upgraded my service to 400Mbps a while back but never got more than about 100 Mbps. I had a service tech out who said that my modem was too old (it was DOCSIS 2) so I upgraded to an Arris SB8200. Recently, I have been having a lot of connection issues, and even when plugged directly into the modem with a CAT6 ethernet cable, I can't get higher than about 95 Mbps. I'm also seeing some concerning errors on the modem logs. Here's what I have:
