Daily outages to my house only

I work from home and my Xfinity internet loses connection every day. Restarting the modem helps, but it’s disruptive as I am constantly getting thrown off my vpn and losing my work. This happens when there are no neighborhood outages. And although I have service at two local addresses, only one is constantly losing connection. Attempts to reach Xfinity through the app have been a total waste of time. Please help!
