UPDATE: Xfinity tech just left after replacing the line coming from the pole to my house (also known as drop?) He told me there was water in the line causing the problem so the line was replaced and now the modem is showing power levels in the correct range!
He was shocked that the previous tech was even able to leave when the initial install happened, everything was in red on their testing equipment. None the less everything seems to be fine for now, will report back if anymore problems occur within the next 24 hours. Again thanks to EG and CCAndrew for helping me with this matter.

Yes I would like to get another tech involved to hopefully resolve this matter.
As for excess splitters and junk gold plated ones I don’t think either of those problems exists. The current splitter installed was supplied by Comcast a few years ago, EXTREME brand.

Hi so on Monday 8/26 I had gigabit internet installed and for the first 2 days everything was going well. I am an online gamer and have been noticing brief disconnects for no more then 30 seconds at most. It usually happens 2-3 times per day so I went over to the event log of my modem (Netgear CM1000). I notice there are critical alerts for quite a few things which is probably causing the disconnects, here is a screenshot of some of those errors https://imgur.com/a/fwFxKrN .
I did a little bit or research/troubleshooting steps such as making sure all cable connections were tight, power cycling the modem(even keeping unplugged for a few minutes) , and checking signal level. I am not technically inclined on exactly what my levels should be but it seems they may be off. Here is a screenshot of those signal levels https://imgur.com/a/nGQhotS .
When the tech was out I asked him if the signal levels looked good and he said yes, I’m not sure if they actually were or if he was just in a rush to get out of here. There was previous service at this address from Xfinity so everything was all ready to go when he got here. Currently there is a 3 way splitter -5.5dB 5-1002MHz on the line (used to be 2 TVs and 1 modem) now we only have 1 TV and 1 modem but the splitter was not replaced. I have a 2 way splitter -3.5dB 5-1002MHz I tried replacing the 3 way with and same effect with the modem event logs just slightly different signal levels.
The problem consists on my whole network when the internet goes down for those 30 or less seconds. Some other info they may be useful is the modem is connected to a Netgear R6400 Router with a CAT cable for Wi-Fi. Then from the router another CAT6 cable to both my gaming console PS4 and PC. The speeds are coming in fine at ~940 download and ~40 upload.
TLDR; Internet going down for a few seconds a few times a day with critical errors in modem event log.
