Every morning offline issues

Every morning I come down to work on our business, which I need to internet to be up & running, it will disconnect numerous times.  This is an issue because I am in the middle of working with accounts and then the internet goes off-line.   Seems when you call them there response is that I need to go & reboot and thats NOT what the problem is.  This issues happens anywhere between 8:00 AM & 10:ish AM.   So something is being done on the other end.   I hope Comcast/Exfinity will get an answer to this problem ASAP.  Its become a major issue.
