Why is Cox Internet Service Continually Intermittent?

The past several days in particular, attempts to watch a simple Netflix movie have been infuriating. The Wii is the only device running on our internet to stream the movies -- which most days stream with no issues. So no, it's not the internet speed - which I have double checked to make sure that I'm getting what I pay for.

That being said, I work from home a lot, and even with my laptop, the service cuts in and out multiple times throughout the day on a regular basis.

I wasn't happy with Cox the last time that I was forced to use its internet service and I am not any happier this time around. I never had any issues like this at my other residence with AT&T U-verse.
