Connection keeps dropping, modem log

For the last three days, starting Monday morning (after I believe Cox pushed some upgrade in the area), the internet connection intermittently drops multiple times throughout the day. Based on the modem log, the error is frequently "Started Unicast Maintenance Ranging - No Response received...". Most recent issue this morning was while streaming an Sirius on an Echo. You can see issue cropped up on 10-5 and has been occurring daily.
