Continuously having intermittent internet outage/sluggish issues

We have always used the Cox supplied Panoramic modem/router for years. Lately, we have had continuous intermittent internet drop issues; internet randomly slows down, sometimes drop off, so,I will do the proverbial “reset” will be fine for a few hours then will slow down or cut off again in the middle of streaming a movie or video… really annoying!!!

• I’ve tried:
  • Resetting the modem again and again
  • Used the Cox Tech Support app also recommending multiple tests/resets/etc.
  • Replaced the Panoramic modem/router a few weeks ago… worked fine for a few days, then the slowing and cutting off all over again
• What’s really frustrating is the very delayed response of my driveway and front door security cameras when a person or package is being delivered.  I have even added several cox pods to augment the signal from my router to the cameras but to no avail.
• unfortunately, Cox is the only internet provider with a fiber optic service in our community.
