Connectivity Issues CM1000

I have had the CM1000 paired with the Asus RT-Ac3100 since last September. Starting about last week I have had connectivity issues that I have never experienced before. I had the blast tier from Comcast usually doing 250 mbps now have their 1 gigabit plan. Anyways for the past week I have been getting drop outs almost everyday and the only way to temporary fix it is to unplug it and then plug it back in to get it running again. Comcast basically started saying it is my router because on their end everything is working as it should. I pulled up the log and I should have taken a picture of it but it was saying something was up from my understanding. I will try to post it tonighg or tomorrow morning but has anyone ever experiecend something like this? What has me confused is why now when it has worked flawlessly before this past week. In the meantime I did move the modem to another part of the house which has newer cable and seeing if that helps.
