Netflix starts and stops

Run an Internet speed test (speedtest.net) on your PC to see what your Internet connection is like...

If you have any other device that can stream Netflix, I'd try that to see if you get similar results, too. But if the app is showing a slow connection speed, that sounds like your problem. Unlikely it's a problem in your in-house wiring.

Use the same test program (the speedtest.net one is well-regarded) at different times of the day so you can see what's going on. If that's really the kind of variance you're getting in speeds, there's something not right.

My father in law had similar problems when streaming anything. It turned out to be the modem, if you are renting the modem ask for a new one if other devices can't stream. When I switched from wireless g to n I bought an all in one modem/router and now I run 4 netflix equipped boxes with no problems, in addition to using internet. Three are wireless and the Blu Ray player in my listening room is wired. If your modem is the bottleneck you'll have all kinds of hiccups and buff ........ering

Try speedtest.net at home, and not at work. The problem is home.

Your agreement with Cox says you should get a certain download speed. If you're not getting what you're paying for, call Cox. Let them fix it, on their dime.

After several back and fourths with Comcast, a couple years ago, I ended up buying my own modem. No issues since.

Try the COX speed tests too, login to your account at cox.net and go to the Internet selection next to My Account & Services on the right.

Then under account management go down to internet speed check and run internet speed check

After you are logged into your cox account go here https://myaccount.cox.net/internettools/speedcheck/speedcheck.cox

We usually have problems with our COX internet connection speed during the evening, that is when most people in the nieghborhood are home and using their internet. Unfortunately this is the problem when the severly oversell your area and don't split the node when it's overloaded. COX won't do anything unless a large number of people in the area complain, but most people aren't tech savvy enough to know they are not getting anywhere near the speed they are paying for. We pay for 18Mbps and right now in the evening we are getting 3Mbps, during the day we get our 18Mbps. Even with that 3Mbps speed nextflix works fine on our smarttv, but you can see the quality degrade when the connection slows down even more.
