Kingswood Parke (Surprise, AZ) Recently infrastructure was updated here now internet keeps dropping

Seven days ago COX made changes to the infrastructure to our community. Numerous folks mentioned recurring outages since then. I have had outages up to five times a day that I'm aware of. I received a new modem from COX and replaced my router as well. Up until that point my equipment showed I was "SECURE, NO INTERNET" now I'm getting the same problem with all my new equipment. This has been very strange for me since I've had COX here since 1997 and it has been OUTSTANDING until this week. Anyone have fixes out there?
