So this router was purchased only a year ago, now its consistent problems.

All of a sudden within the past week it kicks off every device on the network, then restarts, then kicks everything off every 15-30 minutes. Theres only about 7 devices. The device will not show me any logs regarding why it's doing this. 

I restarted the router wiping previous settings and set it up again. This corrected the problems for about 1 day. It started happening again, I reset it again, this time it hasnt corrected the issue. What's upsetting is I see arris doesnt support this router/modem. Personally I think if you arent going to support something or plan to discontinue support for a device within a year it shouldnt be sold.
