I had Time Warner Cable installed roughly a month ago, so far the internet service has been pretty good. I live in Austin, TX and I am currently getting about 15Mbps down and under 1Mbps up.
The plan I have says I should get “up to” 15Mbps+ down and 2Mbps up. This is during the highest traffic time (5pm-10pm).
Overall the internet seems fast enough for my needs. I am satisfied.
