Intermittent connection loss

I started noticing on New Year's Eve that my internet connection would drop intermittently through the day and into the evening. I reset my modem and router repeatedly through the evening until I finally gave up and used my phone as a hot spot. The next day, I resolved to fix the issue by removing the existing router and replacing it with a new router. I did that on New Years Day. However I found that it still dropped connection on all internet connected devices. After a reset of the equipment, everything would be fine. I have not had any issues with my television service.

Today, 1/2/17, I found the internet connection has dropped out twice. Finally I went to look at the status of my cable modem. I have a Zoom 5341J cable modem. I have been using this modem for about 18 months. The only thing that looked odd to me was of the 8 channels on the downstream, Channel 4 was showing correctables and incorrectables. After doing a little more research I have learned that uncorrectables are not necessarily a good thing and could be the crux of my issues. I have definitely confirmed after a reboot of my modem I was able to clear out the correctables and uncorrectables to a count of 0.

The very next time I lost internet at about 4pm EST I found more uncorrectables listed. I have not changed any equipment or made any service changes during the life of this modem. I clearly have a problem, I am just unsure of where to begin looking for the issue. Any assistance would be appreciated.

    Looking from this end I'm more concerned about the router than the modem. Your subscribed speeds are well above what the router can handle and I suspect it's betting overwhelmed. Can you try connecting a PC with a gigabit Ethernet port to the modem then resetting the modem and see if that works any better?
