Gigabit Problems

I have been on the gigabit plan for about 2 months now without any issues. For about the last week my speed has dropped to around 180 mbits down. I spoke to 2 degrees and they told me there is nothing they can do. I could pay them $50 to reduce my plan back to the 200/20 which is faster than what I am getting now.

I am using the Fritzbox 7490 and connected over ethernet.
