Netgear CM1150V Frequent internet interruptions going on for over 2 weeks. Please help:)

Hello all! I am in need of help. About 2 weeks ago, our internet starting going out and the frequency has gotten worse. Cannot do anything online/stream/game at all. I have called Comcast. The tech came out this past Tuesday and changed "fittings" said they were corroded. It worked for about a day and half, then as of Friday back at the interruptions. I was able to log into my modem and see the event log and mentioned to Comcast "Advanced" tech what I saw, they told me to buy a new modem. I do not want to do that, if at all possible as I just bought this one less than a year ago and it was working fine until this issue. Here is a snippet of the event log below. Can someone help me with this? All I got from Tech support was restart modem or buy a new one.
