I started seeing packet loss and stutters a few days ago as well. Before that everything was working perfectly. Checked the logs today and found this. When my connection was working well I only had about one or two DRW violations per week. Now getting multiple per hour and also had some T3 timeouts that I didn't capture before they scrolled off the bottom. Something definitely changed on the connection. It's not my modem or wiring as confirmed by a recent tech visit. Problem seems to be in the Cox system and seems to be widespread. Hopefully they're looking into it. Trust me, all of our modems and cables didn't go bad at the same time.
You might be on to something about it being caused by the start of school, but I thought a DRW violation was caused by RF problems not by node saturation. Maybe someone can confirm or deny that?
