download speed is unstable - Time Warner Internet

#1
This question is about "download speed is unstable", with Time Warner Cable internet and apps. It just starts like weeks ago, my download speed is unstable. When i test the speed, I always turn off the wifi and connect to the modern directly. The download speed varys from 0.5Mbps to 70 Mbps. The upload is always stable around 6 Mbps.
