5G Home internet keeps dropping!

I got home from 10 days of vacation and found that my internet kept dropping out a few minutes after rebooting the router. When I connected a device directly via an ethernet cable the connection time was elongated by about an hour but still would fail. I have opened many service tickets regarding this with no correction. They tell me that they are working through the engineers to correct a software issue but I have found that it is still failing after three days of this continual reboot and use for a short period of time. At this point it fails immediately upon reboot. The device still says it is connected to the Internet although all connected devices to the Wi-Fi or ethernet port say there is no Internet. I am at the end of my rope  for how to get this resolved through technical support.
