CM1200 Amber Upstream Light and Occasionally Blinking Downstream Light

Somewhat of an update. It's still an ongoing battle. About a month after my last response, my connection dropped again, and my upstream light was once again blinking green. Spectrum sent out a technician who identified an issue with the line being chewed out by a squirrel, possibly, so the technician (Adam) replaced the entire line leading up to cable box outside the home.

I was still seeing a blinking green upstream light, but since I live with someone who is considered high-risk IRT COVID-19, I thanked Adam for his help and did not let him into the home. My internet was still dropping every 10-20 minutes, but perhaps 3 hours later, my internet connection finally stabilized despite having the blinking green upstream light.

A few days afterwards, my power did go out, so when my power came back on, I continued to have internet issues for the first few hours until my internet had restablized itself even with the blinking green upstream light (I know I sound like a parrot now, but I want to be extra clear when reporting my observations).

Very recently, perhaps another month since Adam had replaced the line, my internet randomly dropped again, and continued to sporadically drop for the entire day and midway through the next day as well. I did perform a couple of fixes, but I am not certain as to how effective they were:

1. I enabled the checkbox in my modem settings for Extended Upstream Power.
2. I cleared my Firefox history and cache.
3. I ran a full System Scan with Bitdefender.

Now actions #2 and #3 seem rather silly, but I had recently seen a Reddit post about a Facebook crawler making millions of requests to someone's website; while this post may seem irrelevant, I found myself wondering whether I had any trackers or crawlers consuming my bandwidth in the background, so I carried out actions #2 and #3.

I found my internet working again after my Bitdefender system scan had completed hours later, but I was not checking my connection during the scan, and I was not testing my connection immediately after the scan either, so I am led to believe my connection resolved itself for one of these reasons:

1. My modem got lucky and found a good upstream channel.
2. Spectrum must have improved their stability.
3. My Bitdefender scan, while it did not detect or remove any types of malware, may have done something beneficial to my connection.

This is my status as of 7/26/2020. My upstream light is still blinking green, but my connection works reliably (enough to game, use Discord, and work from home via a VPN).
