I'm glad your Netflix is working better. Have you tried any online tests for packet loss? Any at all is considered unacceptable and they would work towards fixing that if discovered.
I work at home on a network and internet service has to be about perfect. My co-workers and I do have occasional problems with our ISPs, but they eventually get issues solved 99% of the time. Sometimes, they need a little diagnostic help... The techs in the Cox forum here seem very good. Maybe they could take a more in depth look at your line stats and find the problem. Good luck!
The phone support people mean well, but they're not as well trained as you'd think in many cases. Let's just say I should know...
