Connection drop and packet loss issues - Time Warner Internet

This question is about "Connection drop and packet loss issues", with Time Warner Cable internet and apps. I am experiencing disconnections during online gameplay, to include packet loss indicators being reported. Streaming shows also appears to have an issue every so often.

Is this an issue with the lines outside my residence or is it the modem? How would I go about troubleshooting where the problem is to get it fixed?
