Internet completely dropping 5-10 times throughout the day.

I've been experiencing this problem for almost the entirety of the last 6 months. Throughout the day at random intervals, our internet drops for anywhere from 30 seconds to up to 5 minutes. It is extremely frustrating for the entire family, whether it means being on a zoom call, gaming, streaming a show, or whatever it may be. It has interrupted my son's schooling multiple times as well, when he has online classes, and I'm concerned that it may be affecting his learning. So far after working this up as best as I can, these are what I've tried:

• Switching coax cables
• Switching to a new coax connection in the wall
• Wifi vs ethernet (drops with both connections)
• Plugging directly into the comcast-supplied modem
• Using a new ethernet cord
• Resetting all of my devices
• Checked all splits and further connections

And nothing has seemed to work. It continues to drop multiple times per day. I have been scouring the forums and see many, many posts suggesting the same is happening to them and there are no visible, effective solutions that are posted. Surely this cannot be an issue that I just have to deal with, because for what I am paying, this is not acceptable. This has only begun to happen over the past six months as well, so I know it must not be an issue with connection to the home. Xfinity virtual assistant cannot help with this, as it keeps cutting me off and saying I have no issues. I need a solution to this.
