Internet goes in and out daily

I have been a user of xfinity internet for years and never have had the problems I am having now with the Internet dropping in and out daily for months now. It is getting worse. We even connected the PC cable into the modem only and not the router. Right now it is working but an hour ago I was dropped on the internet. We work from home and this is really getting bad. Have they done anything on the West side of Tupelo, Mississippi?
