I pay for 50down, 5up. I get the speeds most of the time. Not a problem.
However, anytime (100% of the time) if i use any bandwidth (WITH program/download/livestreaming/etc, download or especially upload) my internet connection response time as a whole, go through the roof.
The easiest example of usage would be to just do a normal speed test:
If im in a game the ping would skyrocket (especially during upload test) and experience massive delays,
Pinging google.com -> add an additional few hundred ms while test being downloaded/uploaded
Browsing or loading video (4K video, etc) -> massive slowdown
Or often I would stream to twitch.tv with open broadcaster software. When i was using comcast in another city its natural to stream @ 3500kb/s bitrates. But if i use that setting my connection response times would all shit itself. Have to lower it to 1000-1800kb/s.
Most of my usage i don't even reach half the speeds i pay for, but experience consistent response time hauls.
Talked to TWC tech support supervisors and TWC office tech supervisors, they are all fairly useless. Although can be assured there is no problem with my software or hardware. One of the retarded supervisors at the TWC office kept repeating to me if "your using your speeds of course your internet will slow down!"
TL:DR: Connection speeds look great, but if any decent usage of bandwidth connection response times go through the roof.
Help/suggestions/ideas, thanks
