Internet connection drops several times a day. This happens almost everyday!

Hello. I have been dealing with this issue for a while now and finally ran out of patience, so I called and they sent a tech out. The tech was unable to find anything wrong with wiring. My router was very behind in firmware updates, so we were hopeful that updates would solve the issue, it didnt. He said if that didnt fix it, then to plug into my modem directly. I did that and it still didnt fix it. I was thinking I have had this equipment for a while now (5-6 years) so I went and bought a new modem today and plugged my PC into that. The problem still persists! I was planning on calling again tomorrow, but came across this forum and wanted to see if I could get some recommendations since I've seen lots of people get help here! I logged into my modem and have a screenshot of my Downstream Bonded Channels since I saw this is what people were posting. Any help is much appreciated! Thank you for your time!
