A couple of year ago when I first subscribed to Netflix I got excellent streaming. But for about a year now performance is erratic. Sometimes it takes a while for a movie to start, then it occasionally stops to catch up. Netflix says something like "the speed on your end is inconsistent, so it's your problem."

My Comcast speed is pretty consistently 55-56 Mbps. I'm in Houston and I use a server in Dallas for speed testing. I don't know exactly what the correct Netflix server address is but I'll show the results from a couple:







I don't understand much about this area but it looks like these plots indicate problems. Any help will be appreciated.
