What is wrong with my WiFi Modem?

I've been a customer for a little over a month and a half and since I became a customer I've had so many problems with my internet.

The technician that came in and installed it made a fresh new line. I have no splitters going from my wall to my modem. I have the premier speeds (60 down i believe) and I cant even get online to play a single game on Xbox Live without my internet crashing. its been like this for the last 2-3 days. 

Today I had a tech come by and he added something the the cable port on the modem, checked my speeds and noticed i have a different software version on mine then he had ever seen. 

Anyways, here is a video demonstration of what happens. I cant even play a full game of CoD Ghosts without dropping my connection http://youtu.be/s-Fnm5Vk4F0
