Upgraded Speed

I upgraded my speed to the 2gb down and 300 up, however in some areas of my account it is not showing the updated speeds as well as when i run a speed test i get less than 1gb down and about 40up. (I understand i wont reach the maximums but I'm not even remotely close)

The devices that I'm using are.

My Modem is: ARRIS - S33v2
My Router is: an ASUS - RT-AC86U
