I purchased an Arris S33v2 last November. We have been having at least 2 to 3 short dropouts daily. We thought it might be a cable issue as the upstream voltage was a little high and downstream was a little low. (Also saw some UCD invalid or channel unusable messages in the event log)

Ran a new RG6 Quad coax directly from the outside cable box to the modem. The voltages fell within the normal range but the daily reboots continued.

The Xfinity tech recommended getting a different modem. I already had my old SB8200 so I installed it. It has been up several days now with zero dropouts.

How do I go about getting a warranty replacement?

In this case if your modem is under warranty you can reach out to Arris.co/consumersupport so you can get connected to our phone support team to proceed further.
