Intermittent connection drops
Starting a couple of weeks ago I have been losing connection issues ~5 times per day. Sometimes the connection re-establishes itself after a couple of minutes. Other times I lose the connection to internet completely and I have to reboot the modem (Motorola MB8611). It's a new modem. I was having this same problem with my old modem as well.
Here is a log from my cable modem from when I was experiencing a failure. This one manage to re-connect after a few minutes.
