I have 115 down and 12 up.
I just recently moved to a new house and this issue has never occurred at my previous location. I mainly noticed this issue when I decided to download a game from Steam. As the video game was downloading, I noticed it would reach peak speed (around 14mb/s) and then instantly drop to 0 mb/s. Then would would climb back to peak speed and again drop back to 0. Almost like a roller coaster.

Okay! Maybe it's just steam being retarded. Then I noticed that sometimes when I attempted to load a website, the site would load to the page that says something a long the lines "Website could not be accessed due to no connection", but then 2 seconds later the website would reload itself and load properly.
I called the ISP and explained to them the issue. They sent a guy out and told me the signals were perfect and it was probably my computer. Then he left.
What exactly is happening with my internet? Is there any way I can figure this out, or should I keep calling my ISP until I get someone out here that does more than "check the signal"
