Intermittent disconnects through the day.
I moved to a new home back in December and since then, my internet has been awful. I'm getting random disconnects throughout the day which some lasts a few seconds but sometimes it can go for minutes. This might not seem like a big deal but when you're working from home joining Zoom meetings all day with customers and getting disconnected constantly, it ends up being very nerve racking as my job depends on my internet reliability.
Enough said, I tried contacting customer service already in the past, a tech was sent out and no signal issues were detected with splitters and without splitters. I tried three different modems and the issues persisted with all of them. (Arris SB6141, Arris S33 and Netgear C6300)
Going through the logs of the modem, I noticed that I'm getting flooded with DoS attacks to my public IP in which I contact Xfinity's support but didn't get anywhere. All they ask is to reboot the modem and run some type of analyzes on the back end which obviously doesn't really do anything:

At 9:02AM, I got disconnected. See below:

As stated, an Xfinity tech has already been sent out in the past who blamed my modem for being faulty, but again, I tried three different modems and have the same issues with all of them. They seem to have ran 3-4 new coax from the street to the house which I'm guessing this could have been an issue prior to us moving to this new house. The tech did check the splitters and didn't find any issues.
At my previous condo which is 5 blocks from where I currently live, I had no issues.
I'm at the point that I'm considering trying a different provider (At&t Fiber) as I can't seem to reach anyone on Xfinitys side that will assist and resolve this issue once in for all. This post is not to complain as I've been an Xfinity customer for a long time and the service has always been reliable in the past. I'm simply looking for assistance and resolution on getting this fixed.
Thank you.

I have the same exact issue, minus the DDoS attacks. Exactly the same. Had a tech come out, he replaced the cable going to our house, but no improvement. Similar messages on my modem to yours:
Xfinity is the only provider in my neighborhood so I am quite stuck here until Xfinity finds a way to fix this issue once and for all, but it's very difficult to reach any help.

Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
