Dave cut the cable with Time Warner. He's now using Netflix, but he's suffering from severe a slowdown from 20MB to 0.5 MB down. Leo says that's because everyone in Dave's neighborhood is watching Netflix all at the same time. Leo also thinks that Comcast is slowing down Netflix traffic on purpose. So Time Warner cable may be doing the same thing. Leo also says that it may be Wi-Fi congestion. Try connecting a hardwire and see if the streaming improves. If it doesn't, then it's clear that Dave's internet service is being throttled.
