Internet keeps disconnecting

My xfinity internet has been disconnecting regularly about 5-10 times a day in the last week or so. Previously never had this problem. I have gigabit internet, I've reset the router several times even shut it off today for about 4 hours to try and reset the IP lease, still disconnecting after that. This is happening both over wi-fi and ethernet connected devices. Happening while working, gaming, and streaming shows like netflix etc. Both my spouse and myself work from home as attorneys and cannot be having this happen during calls, not to mention how annoying it is when were using it for entertainment purposes. 

If anyone has any other ideas to try or has suggestions for other good ISP's I'm all ears. Thank you.
