Hopefully this is the correct place for this. I have gigabit internet through Atlantic Boradband, they sent us the rental modem and it worked maybe 50% of the time out of the box. After 2 days I went and picked up a new SB8200 Sunday and everything worked great for a while. That Monday morning around 8 AM we lost internet, reset the modem and internet came right back and lasted until about 5 PM. Another reset and we were good to go again. Tuesday morning right around the same time internet dropped, reset, and fine until around 5.
It's been doing this everyday since I got it and almost always around the same time. Whenever it happens all the lights on the front of the modem all show as if nothing is wrong. I've checked the logs and whatever is happening either isn't getting logged or they reset everything I reset the modem.
I'm almost thinking its an issue with the coax or isp since the rental modem was doing something similar but wouldn't get internet back for hours after I reset it but my original modem (arris SBG6700) never had to be reset in the 4+ years I've had it.
