I have had a cable modem break from me turning on extra logging and or statistics that apparently worked badly. Turn off any extras you turned on. Mine was also having random issues from a zwave transmitter tnat was really close. The zwave caused errors on 2 of the many different frequencies on the cable that told me it was not a physical wiring issue but something else. I found those stats in one of the cable modems pages. Moving the device a few feet away resolved thay.
