Intermittent Internet Connection

Hello,

I'm at a loss for what else to try! I've been having intermittent internet issues for about 4 or 5 months now where my internet disconnects EVERY DAY. My download/upload speeds are fast (they do not slow down), and then randomly my internet cuts out on both the ethernet and wifi (my laptop that is hardwired will disconnect and my TV, Alexa devices and cell phone disconnect too). For the last month I've been tracking what time the internet disconnects and there is no trend, but it happens 1 or 2 times a day. Usually it disconnects for about 1-5 minutes and then is back up. I work from home, so even a couple minutes offline is incredibly frustrating as I'm usually in meetings, presenting, and on camera. It disconnects randomly at 3:23pm or at 9:26am or at 5:00pm. 

I've had several technicians come to my home just to tell me the wires and everything looks "good". I was even charged $100 for my last visit on 12/4/22 even though the issue is still happening! One of the techs suggested I purchase a new modem/router because my Motorola was getting old. October of this year I bought the Netgear Nighthawk and I'm still having the same issue - which makes me believe it's not the modem/router and I spent another couple hundred dollars for nothing. I've contacted Netgear, they've run tests and also say it's not the new modem, it's the connection, but no one can figure it out.

I've chatted and called Xfinity so many times with no resolution. They have tried to reconfigure settings and send signals. I try to call as soon as my internet cuts out, but by the time I have someone on the phone, it's working again and they can't see the issue. 

Has anyone else experienced this? Any suggestions? Please help!
