Having Daily Dropoffs

Shortly after receiving text messages about work being done in my area and that I might experience some outages my router started having issues syncing with the DHCP service. I suspected that it might have been my router, even tough it was only 6 months old, so I replaced it. I'm still experiencing the same issues with the new router. I now believe this is either a connectivity issue or a setup issue on Xfinity's end. The main line from outside the house goes straight into my router so there are no potential signal losses from that side.
