Having same problem with mine called Arris said upstream signal is to weak to stay connected. Cox was not willing to help tryed to sell me an upgrade and charge to send a tech out. It was working fine up until Fri evening.
This is not a coincidence that a lot of people with the same model of Arris modem started to have this problem in the same week. I got the same response from Cox, they first tried to sell me an upgrade and then they wanted to send a tech out because they are the only ones who can put in a ticket for a higher tiered more knowledgeable techs to dive deeper into the problem. Someone had a similar problem in the forums with the same model Arris Modem which started rebooting around the same time as mine did, he said his problem magically disappeared when he signed up for cox complete care. It's all very strange because it's obvious there is no interruption of service, it's just being made to reboot. But I'm not getting any answers from Cox other than buying new equipment or a service plan.
